[Getdp] getdp Digest, Vol 91, Issue 4

[Zacharie De Grève]

Hello Ruth,

It works now, with the two solutions you proposed (umfpack and mumps). Thanks 
for your help.

I have tried it on a much bigger mesh (more or less 40000 dofs), with the 
command 'getdp <pro-file> -msh <msh-file>' etc. But umfpack still performs 
better than mumps (approximately 20% faster). 

Maybe it is due to a wrong step/missing option during the compilations of 
Petsc and GetDP ? I employed the following commands on a Kubuntu 10.04 
distribution:

* Petsc :
1. ./config/configure.py --with-debugging=0 --with-clanguage=cxx --with-shared=0 
--with-x=0 --download-mumps=ifneeded --download-parmetis=ifneeded --download-
scalapack=ifneeded --download-blacs=ifneeded --with-scalar-type=complex --
download-openmpi=ifneeded
2. make PETSC_DIR=..._ARCH=linux-gnu-cxx-opt all test

* GetDP 
./configure --with-petsc-prefix=... --with-petsc-arch=...
make 

Thank you again.

Zacharie
