Hey!

Due to my project I need to do a simulation with Fluent. Everything went well until I started the simulation. After some time there was an error and Fluent simply closed. Since then Fluent fails to start when I want to open the project. I can still open the model in DesignModeler or for meshing. I red in other discussions that this might be because of meshing or geometry things. So I surpressed all bodies except a single cylinder. But there was still the same error:

A few seconds before Fluent crashes there is the following status in the console in Fluent:

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

Error: Object: ()

 

I also checked up if it is a problem with the RAM but there is still enough capacity when Fluent crashes.

 

Thank you for your help!

Can you try reading the case in Fluent but outside of the Workbench?

Hi Amine,

thanks for your help.

In the project folders I am not able to find a Fluent-Case-file. I compared this to an other project. Is it true that the .gz-file should be in the folder "dp0 --> FFF --> Fluent"? In this folder there is only a "FFF.set"-file. I didn't delete anything.

Thanks und best regards!

Can you export the mesh and then in Standalone try setting the case from scratch?

Hey Amine,

thanks for your help. When I export the mesh and then diretly import it to Fluent it works!

Best regards!
