[petsc-users] Meaning of Caught signal number 15 Terminate: Some process (or the batch system) has told this process to end

Hi,

are you running the code on a cluster? If so, you need to submit your 
jobs through the batch system, as larger jobs get killed by the batch 
system.

Best regards,
Karli
