I tried to run a compressible calculation on version 7.04 downloaded from the web site installed on a ubuntu WSL2.
I cant upload the mesh, too data. This is the error that I get

Code: Select all

SIGSEGV signal (forbidden memory area access) intercepted!

I overcome the previous errror checking the "hydrostatic equilibrium at wall" box.
But now I got the following error:

Code: Select all

Hello,

Thanks for the feedback on the previous thread.

But please do not hijack an existing thread, at least when it is old. This makes searching through the history more difficult for us, as if we go back a few posts, we will see different explanations.

I made the same remark to another user on this same thread. So if you read this thread, you must have seen it. this remark applies to everyone. So please create a new thread instead.

Also, try to post a longer part of the error message. I do not even know whether you have a SIGSEGV, floating-point exception,
or other type of error, and this information is essential for debugging...

Best regards,

Yvan

[edit : I have split this thread from the previous one]

Thanks.
I'll create a new thread.
