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.
