What cause "segmentation violation"
 

I run a case and it looks converge from residual curve. All residual goes to decrease. However, it shows error "segmentation violation" and stops running every time when the iteration number is 249. I really don't know where this error comes from. What situation could cause this error and How many propability could cause that error? Is it the bug in FLUENT? Thanks.

Re: What cause "segmentation violation"
 

Hi

There could be several reasons for segmentation violation. The primary one is: 'illegal acesss to Fluent's memory' by your case. At somewhere in your calculations, you are trying to access a location, where you are not supposed to. or If you are using UDMIs, not declaring the memories, leads to this type of error.

Hope this helps,

I have run into this problem too. How can we solve that? It's also said " EOF on stderr" . I have no idea what it means. Please help me out. Regards
