Error car invalid argument 1 wrong type not a pair

…По вычисленным углам с помощью фильтра Калмана в Матлабе вычисляю

угловую скорость. Получается неплохо…

Думаю лучше всё-таки использовать те значения, на основе которых получает перемещения fluent.

…Как реализовать неперестраиваемую сетку вокруг контейнера,

если он выбрасывается из носителя…

Там весьма обширные технологические пространства, так что с этим пока проблема не встала в полный рост.

…Встречный поток: его можно создать как обычно путем назначения скорости

на входе и pressure outlet на выходе канала…

А насколько плохо использование outflow? Вопрос для меня отнюдь не праздный.

…Стартовую скорость выбрасываемого контейнера можно задать назначением

таковой на панели Define — Dynamic Mesh — Zones в окнах…

Было дело ставил сразу порядочную скорость. Как итог — происходит удар в первый же момент времени, тут же безумная потеря в скорости. Теперь многострадальное тело приходится сперва нежно разгонять с нуля.

…Хорошо бы такую задачу моделировать в Fluent12.1, в нем

есть кое-что для улучшения стабильности решения…

А что именно?

В довесок привожу то, чем пользуюсь сам (прошу не судить строго — я только учусь))):

#include «udf.h»

#include «stdio.h» /* Стандартный ввод/вывод */

#define Pi 3.14159265359;

FLUENT 6.2 — Using a material properties database generated with a previous version produces the Error: GENERAL-CAR-CDR: invalid argument [1]: improper list

Error: GENERAL-CAR-CDR: invalid argument [1]: improper list
Error Object: «cell_density::libudf»

FLUENT 6.2.16 has new syntax rules due to the addition of a new feature that allows for multiple UDFs (libudf) to be hooked within a case. The case file generated with an earlier FLUENT version will have an additional period (.) that has to be deleted for it to work within FLUENT 6.2. See example below:

density (user-defined . «cell_density::libudf») -incorrect
density (user-defined «cell_density::libudf») -corrected

Use a text editor such as «vi» on UNIX/LINUX or Textpad on Windows to edit the case file.

Error general car cdr invalid argument 1 improper list

I’m currently trying to run a 1mil cell mesh but everytime I load it I get the following error
Setting Post Processing and Surfaces information .
Error: GENERAL-CAR-CDR: invalid argument [1]: improper list
Error Object: #f

I will also get an error stating «material air not available» but this one only appears some times. I have tried re-defining my material from the Fluent database but that doesn’t work.

The above errors are preventing me from using my Parameter Set in workbench which would be very helpful to use as I have a bunch of design points I need to run. I can run my cases by manually clicking Calculate.

If it helps at all this is the error workbench gives me when I try to run a parameter set:
Error Occured during handling message in WorkBench: An error occured in FLUENT when applying cx state information.
The cortex state and surfaces could not be updated

Any help is much appreciated!!

Error: invalid argument [1]: improper list

CFD Online Discussion Forums > Software User Forums > ANSYS > ANSYS Error: invalid argument [1]: improper list

—>

I have a very large mesh (ab. 2.000.000 cells) with k-w, no energy eq. that runs not very stable. However, it runs

But, when I interupt iterating, save the file, take a look at the results and start again, Fluent gives following message:

Error: GENERAL-CAR-CDR: invalid argument [1]: improper list

When I read case and data again, the iteration works fine. until I turn on energy eq. or another turbulence model. Once, i run it laminar, and when i turn on any turb. model, the error message came.

So any help is highly appreciated.

thanks for answer, but it didn’t worked. Could it be because of the error message fluend gives, when it reades the grid:

Warning: Number of nodes read (1057672) does not match number referenced (1056748).

Resetting counter to match the number referenced.

Ther is somewere a volume, that has only one face meshed, and that is not exported — could that be the reason??

I thing the problem is solved, at least it didn’t appear any more.

I don’t know, what is different — i worked on the grid again and made it really good quality mesh (ab 95% of the cells have a skewness below 0.2

I read the mesh again, iterated, saved, turned on energy eq. iterated again and the error appears again

Than I read the file again, iterated untill convergence, turned on energy eq. and continued to iterate was no problem!! Until now, the file runs very fine!

So, what ever the problem of fluent is — it seems to me to be a little random. However, hoping that «&*’?»§$ error will not appear anymore!

I happen to get the same error in fluent when I try to load MHD add-on module after selecting non-premixed combustion.

Can someone point out to why is it happening?

Error: GENERAL CAR CDR — User-Defined-Material-Database

CFD Online Discussion Forums > Software User Forums > ANSYS > ANSYS Error: GENERAL CAR CDR — User-Defined-Material-Database

—>

I would like to create two fabrics using the User Defined Material Database in Fluent.
I am working with Ansys 2020 R1 or R2 (both in use — files do not mix).
For this I used the following procedure:

I created an empty Scheme file and edited it with Fluent.
There I set constant values for the acentric factor and the kiritic point. For cp, density, thermal conductivity and viscosity I want piecwise polynomial (3 rank with 3 coefficients).
I had also tried polyinomial with 7 coefficients.

I get the same error every time:
Error: GENERAL-CAR-CDR: invalid argument [1]: improper list

This error appears every time when starting the calculation and very often already when copying from the User-Defined-Material-Database.

I have also tried the following way.
user defined new material

But for this I copied the materials from the Scheme file. This leads to the fact that the substances appear in the Fluent-Database, but this leads to the same error when I want to copy/create the substances.

Is it possibly due to the piecewise polynomial assignment?
Have I ignored a step or am I forgetting something in the schema file?

Using tmerge First, create multiple mesh files, then combine them into a single mesh file using tmerge before starting the solver. You can also apply rotation, scaling, or translation prior to combining them in tmerge.

1. Run utility tmerge -3d (in a 3D case) or enter utility tmerge -2d (in a 2D case) in the DOS command prompt or Linux/UNIX prompt.
2. When prompted, enter the name of the output file after coupling to the input file name.
3. For each input file, you can specify magnification, translation, or rotation.

If you do not need to use any of those options, combine the inputs with the following TUI: utility tmerge -2d -cl -p my1.msh my2.msh final.msh

I found this page explaining that some of the gimp functions won’t return values consistently, so I implemented a do while loop to make sure the functions are returning pairs before using car. Still, I get the error Error: ( : 1) car: argument 1 must be: pair, but I’m not sure how that’s possible as it should keep running the function until it returns a pair.
