ParFEAP and user element with element equations

[wklausler]

Hello FEAP community,

I have a user element with element equations that works as expected in serial FEAP. However, when I run a simulation in parFEAP with the element, the simulation crashes from PETSc's side, with the error message starting with

[0 ]PETSC ERROR: Argument out of range
[0 ]PETSC ERROR: New nonzero at (682,580) caused a malloc
Use MatSetOption(A, MAT_NEW_NONZERO_ALLOCATION_ERR, PETSC_FALSE) to turn off this check
[0 ]PETSC ERROR: WARNING! There are option(s) set that were not used! Could be the program crashed before they were used or a spelling mistake, etc!
[0 ]PETSC ERROR: Option left: name:-ksp_type value: minres
[0 ]PETSC ERROR: See https://petsc.org/release/faq/ for trouble shooting.
[0 ]PETSC ERROR: Petsc Release Version 3.18.3, unknown

This message suggests a problem in defining the structure of the system matrix. Is there any consideration I have to make in my user element when using element equations for use in parFEAP?

Thanks and best regards,

This is a point on my to-do list.  Right now element equations will not work with parFEAP.

Okay, thanks for the information
