<p class="MsoNormal"><span style="font-size:11.0pt">GAMG needs the kernel of the operator to build the coarsening spaces. In elasticity, these are the translation and the rotations. If I were to solve the Stokes problem using the Schur complement approach and
I wanted to use GAMG for the Laplacian of the velocity block, should I pass the kernel as well? Is this kernel made of translation and rotation (of the velocity)? I haven’t found anything like this in the literature, hence my question.<o:p></o:p></span></p>
