killed "snappyHexMesh"
 

hi all

I'v run the snappyHexMesh and got the problem, Killed..

Anyone can help me, please ?

thanks//

Probably you have "ulimit" set to a smaller value for the process memory than what snappyHexMesh would want to use for your case. If that happens, the system will kill the snappyHexMesh process.

thank you for your reply.
