Hello every one,

I have a problem who works with Edge03d . but when I change it to Edge13d it gives me an execution error :  
Erreur Mumps mpi: number -13  
Fatal Erreur MUMPS\_mpi Factorize  
current line = 496 mpirank 0 / 1  
Exec error : MUMPS\_mpi Factorize  
– number :0  
ORAS :  
\*\* Instance Error 1 in ZMUMPS\_F77

Do you know what is the problem?  
Thanks.

the error -13 is:  
–13 Problem of workspace allocation of size INFO(2) during the factorization or solve steps. The size that the package tried to allocate with a Fortran ALLOCATE statement is available in INFO(2). If INFO(2) is negative, then the size that the package requested is obtained by multiplying the absolute value of INFO(2) by 1 million. In general, the unit for INFO(2) is the number of scalar entries of the type of the input matrix (real, complex, single or double precision).

Thanks for your reply,

do you think I have to simplify my mesh structure to solve this issue or there is another solution?  
I tried to calculate magnetic field with edge23d or edge13d for a simple mesh and it was ok, however when I solve a more complex mesh with edge 13d or edge 23d I get this “Mumps mpi: number -13” error.  
it works correctly for edge03d.

Regards.
