<div style="line-height:1.7;color:#000000;font-size:14px;font-family:arial"><DIV>Hello,</DIV>
<DIV> I want to use the multigrid as a preconditioner. The introduction about it in the manual is little.</DIV>
<DIV>So are there some typical examples or details about multigrid? Is it used just like other preconditioners</DIV>
<DIV>like jacobi, sor, which can be simply used in the cammand line options?</DIV>
<DIV> Thanks.</DIV>
