I'm implementing staggered grid in a PETSc-canonical way, trying to build a custom DM object, attach it to SNES, that should later transfered it further to KSP and PC.<br>
<br>
Yet, the Galerking coarsening for staggered grid is non-symmetric. The question is how possible is it that DMShellSetCreateRestriction can be implemented and included in 3.7 release?<br></blockquote><div><br></div></span><div>It's a little more work than just adding a new method within the DM and a new APIs for DMCreateRestriction() and DMShellSetCreateRestriction().<br></div><div>PCMG needs to be modified to call DMCreateRestriction(). <br></div></div></div></div></blockquote><div><br></div><div>Dave is correct. Currently, PCMG only calls DMCreateInterpolation().
