StatAcceleration
Handle stationary acceleration for nonlinear problems with time-periodic stationary solution.
Syntax
model.sol(sname).feature(solv).create(fname,"StatAcceleration")
Description
This feature can added as a subfeature to the Time-Dependent Solver and the Time Discrete Solver. Instead of time marching the problem from start to finish, the Stationary Acceleration node solves for a number of periods and then extrapolates the solution forward in time based on the average solution and the average time derivative. This solution process is repeated until the average time derivative has reached steady state.
