Simulation Error


#1

Hi,

I am currently working on a CFD project with the CAD of a vehicle that includes external and internal flows.
I had previously run 2 simulations and they both worked. I have uploaded 3 new CAD´s with geometry changes, the meshes were created accordingly, but when I want to run the simulation with the same parameters, none of the 3 meshes run. I have tried re-modifying and re-uploading the CAD but the same problem is obtained.
The project link is: https: //www.simscale.com/projects/cmartiso/uni_-_rp/
Could someone please help me out?

Thank you!
Carla

Hi @cmartiso,

currently running a simulation and getting back to you as soon as the run has finished.

Hi @jousefm

That´s great! Thank you :slight_smile:

Hey @cmartiso!

You should have an email - shared two finished runs with you.

P.S.: Make sure that the turb. kinetic energy and the dissipation rate are calculated properly. For more information, please have a look at: Defining Turbulent Boundary Conditions

Best,

Hi @jousefm!

Thank you for your help! I have read your turbulent constants, and with the equations and some wind tunnel data I have obtained different constants, will try them out!

Thank you very much! :slight_smile:
