Error allocating real buffer for matrix distribution
« on: October 14, 2020, 08:20:47 AM »
Hello,

Has anyone received the following error messages from FEAP?

 ** Error allocating real buffer for matrix distribution
 ** Error allocating int buffer for matrix distribution
 ** Error allocating IW4 for matrix distribution

I am solving a transient problem employing mumps solver, and got this error after successful calculations of about a thousand time-steps. It causes an unexpected termination of the simulation. Does anyone have a clue of this error?

Thank you.

Prof. S. Govindjee

These are MUMPS error messages.  For example, the IW4 message comes from subroutine ZMUMPS_REDISTRIBUTION.   You will need to add some additional error diagnostics to the MUMPS routines to figure out why this is occurring.  However, I would recommend first checking the validity of the parameters that you are passing to MUMPS first, before trying to debug MUMPS.
