Hello everyone, I've been trying to set up a geometric multigrid preconditioner (following step 16) for an HDG Poisson solver. I was able to set up all the MGLevelObjects but the MGTransferPrebuilt class isn't able to generate the prolongation matrices.
Has anyone been successful in implementing a geometric multigrid preconditioner for an HDG solver? How would one go about building the transfer operations for the HDG finite element space? Some relevant papers: 1. Cockburn 2013 - https://doi.org/10.1093/imanum/drt024 2.
