Hello,
For a transient problem, [A]{x}t={b}t ,the RHS {b}t is time-varying and depends on the previous {b}t-dt, but [A] is constant. So during a complete analysis, we need to do factorization only once, and use this factorization to solve successive RHS.
In this situation, multi-rhs is not suitable, and I tried to call the complete Pardiso (phase=11, 22, 33 and not execute phase=-1) at the 1st time step, then only executed phase=33 at later time steps. This way did not work however.
Do you have any suggestion?
I know there is a similar question, but the answers below don't seem to work either.
