Title: Error just after the start
Post by: Inaoton on June 9, 2017, 08:30

Sir
           I got an error message in the log file saying
 ** Back Engine Exception : PETSc error 55 of type 0 in PetscMallocAlign:46: Memory requested 116330528
** Location of Exception : initialize.cpp:34
         Could you please give me suggestions how to rectify it?

Looks like you are running out of memory. Have you tried to get an estimate of how much is needed? I think the unit is bytes, so the error message indicates that you need at least 116 Gb.
