We present a mathematical model for the charging simulation of pancake solenoids and propose its fully discrete backward-Euler scheme. The parallel implementation of the scheme is done in Petra-M. The scalability analysis is performed with the iterative and direct solvers for both single turn single pancake and twenty turns double pancakes solenoids. We observe the iterative solver together with the appropriate preconditioner outperforms over the direct solver in both cases.
