The version on the web is precompiled with petsc. <br>
<a class="moz-txt-link-freetext" href="http://geuz.org/getdp/">http://geuz.org/getdp/</a><br>
<br>
You can use that one directly.<br>
The file solver.par is then not needed.<br>
You can indicate your solver options in the command line, e.g.:<br>
Iterative solver<br>
getdp kkkk.pro -sol -ksp_type gmres -ksp_rtol 1e-6 -ksp_gmres_restart
200<br>
Direct solver:<br>
getdp kkkk.pro -sol xxxxxx -ksp_type preonly -pc_type lu -mat_type
umfpack<br>
<br>
<br>
You could also use a file '.petscrc' for indicating your options. This
file is searched in your working directory or home directory.<br>
By default, getdp uses a krylov iterative solver (gmres).<br>
<br>
Hope that helps,<br>

Can you send me more info (or executable) about this? I think I will need solution to get results faster (calculation time), because I think of doing non-linear material after this works. I suppose the compilation time will increase a lot agian...

<pre wrap="">hi all,
I have a working description of a magnetostatic 3D problem with B-conforming formulation and around 100.000 tetrahedra in the mesh. My goal is to put 3 systems next to each other to see the neighour influence from one to another electromagnet. This blows the mesh to > 200.000 tetrahedra, and convergence is missing when solving.
I changed the Nb_Fill value in the solver.par file to 80, but still no luck. What is the maximum that can be used for this parameter?
Are there other parameters that influence the convergence?
Is a h-phi formulation better to reach convergence?
