Hi,<br>
<br>
usually I'm using MUMPS by puting '-pc_factor_mat_solver_package mumps' into the .petscrc.<br>
Now I want to change in runtime between MUMPS and non-MUMPS so I tried to turn it on with<br>
PCFactorSetMatSolverPackage( pre, MAT_SOLVER_MUMPS);<br>
but I doesn't have any effect.<br></blockquote><div><br></div><div>This is complicated because you have to set this at the right time during the solver setup process.</div><div>Command line arguments are much easier. However, you should call this after the preconditioner</div>
<div>type is set, but before it is setup.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
I also have a problem with PCFactorGetMatSolverPackage(). How can I get back an output as described in the documentation that has the type 'const'?<br></blockquote><div><br></div><div>What is the problem? I do not understand?</div>
