Question on Geometric Multigrid (GMG) automatic hierarchy generation

Please login with a confirmed email address before reporting spam

Dear all,

Would anybody happen to know whether i can generate more than 1 good multigrid levels automatically by picking lower element order first in the hierarchy generation option in the GMG node provided i used a quadratic element order for my original mesh. My calculation seemed to be a lot slower if i choose to have more than 1 multigrid level.

Best regards,


Aimi
