Hi! I have a quick question about KSP solvers. I will use the KSP solver to solve a time varying problem. My question is: do I need to call the following functions once in initialization, or do I need to call them in the time loop (solving equations in each time step)?
The functions I am not sure about include: KSPSetOperators KSPGetPC PCSetType KSPSetType KSPSetFromOptions Many thanks! _________________________________________________________________ ????????????360??????? http://club.msn.cn/ -------------- next part -------------- An HTML attachment was scrubbed...
