Re: [Question #681146]: GS did not converge in 20k iterations


Question #681146 on Yade changed:

    Status: Open => Needs information

Robert Caulk requested more information:
Please copy and paste your CMAKE output here please, it seems you
compiled without LINSOLV, which means you probably did not install the
necessary LINSOLV dependencies (libmetis, libcholmod, libsuitesparse

useSolver=3 and use solver 4 both use the same direct method (cholesky)
within CHOLMOD. The difference is that useSolver=3 uses the eigen
interface to the suitesparse library while useSolver 4 uses suitesparse
directly. useSolver=4 seems to work with multithreaded CPU so it should
be faster.
