For a stationary problem, select the Stationary Solver. When solving the time-dependent coefficient form problem
the stationary solver searches for a solution where ∂u/∂t = 0. The
Time-Dependent Solver and the stationary solver handle linear as well as nonlinear problems.
In addition to these fundamental solvers, COMSOL includes additional solvers for special applications such as an Optimization Solver (which requires the Optimization Module), a
Time Discrete Solver, an
AWE Solver, and a
Plug Flow Solver (which requires the Chemical Reaction Engineering Module). Some of these solvers are connected to special functionality in the add-on modules.
