Здравствуйте. уважаемые форумчане
Ставлю расчёт на досчитывание ступени компрессора и столкнулся с такой ошибкой 001100279. Читал на форуме, что она связанна с распараллеливанием. На ПК считаю и ставлю Platform MPI Local Parallel. До ошибки значение КПД резко начинает расти. Ниже прикладываю невязки и мониторинг кпд. Обратил также внимание, что в новом ансисе появилось ещё intel mpi local parallel. В чём разница между Platform MPI Local Parallel и intel mpi local parallel?
Заранее спасибо за ответы

Dear CFX Users! I just started up with CFX a few days ago. So hopefully my problem is easily to be answered. Just after the memory allocation while running the solver manager the following error-message occurs without any further hint: Details of error:- —————- Error detected by routine MAKDAT CDANAM = CZIF CDTYPE = CHAR ISIZE = 20 CRESLT = OLD | ERROR #001100279 has occurred in subroutine ErrAction. | Message: stopped in routine MEMERR Probably someone may help me understanding and solving this error! Thanks a lot in advance! Stephan |

Hi Stephan, Try running the simulation again with more memory. You can do that on the solver manager on the advanced tab, put (say) «1.5x» in the memory allocation factor text box. This will increase memory allocation by 1.5 times. Glenn |

Hi Glenn! Thank you for the quick reply! Unfortunately after the increased memory allocation (I rised the memory allocation factor for the solver to successively the maximum (9x) means 500MB of total memory for all stacks. All other parameters of the solver manager were taken by default) the error message remains the same… Is this error message definitely connected to a wrong memory allocation or may there be any shortcoming within my meshes which could lead to such an error? Best regards Stephan |

Hi Stephan, I think that if you give a brief description of what you are doing and the code you are using then someone, with a similar experience may help you out. I had previously received a message that appeared to be a memory problem when actually it was about the license or vise vasa, as well as poor mesh with high aspect ratio or almost zero volume cell. In principle, these errors should be detected at some earlier stage, but at times this does not happen and i do not know why. anne |

Hi Anne What I am trying to do is to model a onephase mixing vessel with two 4-blade-impellers (Moving-Grid-Problem) I think it may be the impellers mesh that is to be improved. I am going to do this and will let you know if it lead to any success. Best Regards Stephan |

Hi Stephan, Single phase rarely gives memory problems if the mesh is correct. As for memory allocation, I never had to go beyond 1.4x with such type of simulation. You may need to check that number of cell in your domain is what you expected/set. Best of luck. anne |

Hello again! You were totally right. The mesh was the Problem: I have got major problems in creating periodicities (in order to crate periodic interfaces for my vessel/impellers) in my mesh builder (CAD2Mesh). I simplified my Geometry (the Bottom of my Vessel) so that CAD2Mesh could apply periodicities at least for the vessel domain (but still not for my impeller domains). However, with this modification the model runs and converges but the solver still identifies two isolated Volumes. Does anyone know how to modify the mesh structure in order to allow the mesh builder to create rotational periodic (means identical) surfaces? Regards Stephan |

You would have to post the whole output file, or at least enough to put it into context for us to help you. But if you are using a beta feature then there is no guarantee things will work. |

I have the following error I have a mesh of 6 lacs, initially the same error came up when the courant number exceeded 1. After decreasing the time-step-size the simulation ran but the error sprang up once again and I get the following error along with the previous one Stopped in routine FPX: C_FPX_HANDLER I have tried allocating more space but that has failed, Can anyone help. |

When looking at the output file the most important error is the first error. After that all the following errors are linked to the first error. If you fix the first error then all the other errors generally go away as well. So the first error is the one to focus your attention on. So ignore the final error talking about error code 1. The first error is an overflow error which is usually caused by numerical instability. The FAQ I linked to describes this in more detail and what to do about it. |

There is an FAQ on overflow errors: https://www.cfd-online.com/Wiki/Ansy…do_about_it.3F If you get an overflow error in parallel but not in serial that means a partition boundary has lined up with a critical flow feature — that could be a free surface, shock wave or other large gradient area. The simplest fix for this is to use a different partitioning algorithm which moves the partition boundary away from the large gradient area. Change from Metis to recursive bisection or one of the other algorithms.

Всем доброго времени суток!
Прошу помочь мне разобраться в чем, может быть причина следующей ошибки.
Решаю задачу теплообмена твердых тел между собой, включающих замкнутые газовые области прозрачные для излучения. В задаче порядка 18 газовых областей, в которых моделируется теплообмен излучением между стенками. Модель излучения Discret Transfer с опцией Surface to Surface. В двух односвязных областях считается течение газа турбулентным, в остальных ламинарное течение (неподвижные газовые области с инициализацией по 0 компонент скорости и давления). Каждая область с расчетам течения содержится в нескольких доменах, соединенных интерфейсами. Неподвижные газовые области (т.е. ламинарные с нулевой инициализацией ) содержаться каждая в своем домене. Все области имеют интерфейсы с твердыми телами.
Задача решается в Ansys CFX v14.5 с и сползованием бетта опции rad data in par file=t, позволяющей просчитывать и сохранять информацию для траекторий лучей для модели Discret Transfer на этапе создания par файла в par файле. Счет начинается с готовым par файлом (декомпозиция производиться отдельно и до процесса решения).
В процессе решения на 1-ой итерации получаю следующую ошибку после первой газовой области (область с ламинарным воздухом):

На данный момент опытным путем установлено, что:
1) Описание ошибки в мануале отсутствует
2) Поиск по интернету по ключевому слову EXTRACT_REAL_VAR результатов не дает
3) Задача без излучения во всех доменах отлично ситается
4) Если отклчить в обоих подвижных воздухов (турбулентных) расчет излучения, то в задаче просчитывается излучение в большем количестве газовых областей (порядка 10-ти), однако ошибка возникает на 11-той области. При этом при одном и том же количестве партиций (par файл не меняется от запуска к запуску) ошибка возникает в другой по номеру партиции не в 194-ой как в примере (Slave partition : 194), наблюдал ошибку в 190-ой партиции.
5) Было как минимум три запуска в которых эта ошибка возникала после просчета излучения в различном количества газовых областей с излучением (в каждой задаче отключалось излучение в разном количестве доменов).
Заранее благодарен за любые мысли и рекомендации.

The ANSYS CFX solver exited with return code 1
Добрый день!
для улучшения сетки, я разбила имеющуюся геометри на два тела с помощью операции
после немного подправила условия граничные, поехало граничное условие in
при запуске решатель вылетает, не дойдя до первой итерации
выдает ошибку
«The ANSYS CFX solver exited with return code 1.»
Подскажите, что нужно исправить, что бы все корректно считалось
Причин может быть много. Выкладывайте свой проект.
подскажите, как выложить проект? через фалообменник? или на сайте как-то можно. в личном меню есть кнопочка файл, но там ограничение 200 Мб стоит
а вы не знаете есть ли подобный пример в тьюториале, мне помнится, что там должно быть что-то такое, но я никак не могу найти
Все ) разобралась и прикрепила )
А что это Вы вообще пытаетесь смоделировать, если не секрет?
Сама физика процесса меня не очень волнует
я считала эту задачу, когда не разделяла на части, и все решалось хорошо. Потом решила разделить на два тела, для удобства создания сетки (в одном объем боди сайз с один значением, в другом теле с другим значением). но видимо я что-то неправильно делаю. первый раз работаю с двумя отдельными объектами в одном проекте
Хочется понять сам принцип работы с операцией slice
может есть какой-то пример в тьюториалах, который поможет мне в этом разобраться
Есть в Help некоторая информация относительно операции Slice, DesignModeler User’s Guide > 3D Modeling > Advanced Features and Tools > Slice
Если Вы применяете операцию Slice, то не забывайте объединять получившиеся тела в Part (В DM выделяете тела в дереве построения, потом нажимаете ПКМ и выбираете Form New Part). Это делается для того, чтобы сетка в месте контакта двух тел совпадала по узлам. Если сетка совпадает по узлам, то необходимость создания интерфейса отпадает.
Ошибка возникала из-за того, что Вы некорректно задали граничные условия.
Немного исправил сетку и подкорректировал ГУ, так что ошибка больше не появляется.

Спасибо большое за помощь.
я вам очень благодарна 🙂

Когда запускаю расчет задачи первый раз то все работает нормально.
Но когда продолжаю расчет или когда данные предыдущего расчета переношу в новый то часто встречаю эту ошибку. В результате пропадают результаты расчета. Т.е. их можно посмотреть в построцессоре но нельзя ни продолжить расчет.
А очень обидно когда пол дня считаешь, а результатов можно сказать нет, т.к. расчет не досчитан. А останавливать расчет приходиться, чтобы сменить схему дискретизации с Upwind на High Rezolution (чтоб сначала лучше сходилось, а потом точнее результат был).
Я еще на всякий случай во время расчета делал бекап с заданным интервалом (30 мин.). К сожалению бекап чудесным образом не сохранил ничего (зачем он тогда нужен?).
И еще вопрос: что нужно делать, чтоб не потерять данные и можно было потом продолжить расчет в таких случаях. Может еще как то надо сохранять данные?
Может самому файл в ручную сохранять?
И жаль что нельзя менять схему дискретизации пока идет расчет.
Результаты расчета при этом спокойно открываютсяв Post-Pro (Rezults).
Тогда по какой причине не продолжается расчет?
Вот отчет из терминала:
Единственное, что нашел в интернете по этому поводу:

Can you just simply copy and paste the text in here?
Besides that .zip file does not work anyway.
Also what simulations are you doing exactly? You’re not exactly spoon feeding us the information we need for us to help you!
ok here we go, in the structural part, earthquake acceleration is given to the columns bottom; in cfx part, we have a two phase (air and water) domain to show the depth of water the column is in, and of course it is coupled to the structural, below is the full out file:

If you’re getting one of the following errors while performing a FSI ( Fluid structure interaction ) simulation using ansys
Fluent coupling error :
+====================================================================+
| System Coupling Exception |
+====================================================================+
| Origin : Transient Structural (Solution) |
| Error Code : 2 |
| Error Description : |
| One or more elements have become highly distorted. Excessive |
| distortion of elements is usually a symptom indicating the need |
| for corrective action elsewhere. Try ramping the load up |
| instead of step applying the load (KBC,1). |
+====================================================================+
CFX coupling error :
+———————————————————————+
| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| CFX encountered the error: Read. Fatal error occurred when reque- |
| sting Total Mesh Displacement for FSI. |
| |
| |
| |
| |
+———————————————————————+
This may occur if your solid is largely deforming at the very first step under your fluid pressure.
Remember that fluent has an operation pressure, cfx has a reference pressure too. All pressures you define are relative to this reference pressure. So it may cause a pressure increase in your model and cause a huge displacement resulting the above error.
Another reason might be if you’re defining velocity inlet in wrong pressure. For example consider a pipe with X axis. Now if you wrongly define the velocity inlet toward Y or Z instead of X axis, the reduction in velocity at wall locations will cause a high pressure increase and same story.
