I am getting an error when iam trying to run a simulation. It had run till some iterations.
I have attached a screen shot. please let me know what is the issue.
Thanks & Regards

Normally this could happen if there is some mismatch between the physics being solved and the Boundary Conditions - and/or lack of enough mesh. The solution appears to be diverging for some reason. Could be flow is approaching sonic/supersonic conditions, and indicated physics doesn't support it. Could also be a mis-match in the dimensions/size. Maybe the geometry values/sizes represent mm, but the material properties are in MKS (meter based), which can cause other issues.
hi, I am doing a external aerodynamic solution wind tunnel on 2 wheeler.
I debugged it, in that I have found that I am giving wind velocity and moving ground wall velocity in same direction.
should I give moving ground wall in opposite?
please let me know

If you're trying to approximate sitting on the 2 wheeler and having air blow at you and the ground moving past you, as in a wind tunnel with a moving belt, the inlet velocity and the wall/ground velocity should both be in the same direction.
Hi, I am getting some wrong results so, currently I am considering only inlet air flow.
If you have any tutorial on this simulation which includes the moving ground wall, kindly send me a link.
Also, I am facing some issues with setup. I tried to setup the model in old hyperworks classic.
I am getting some symmetry warnings.
I dont know old version properly.
I have attached an image. kindly let me know what to do?

Can you attach the .inp and .Log files? Can you also post an image with description of the model - the BCs called out, etc?
