Introduction to hAMSter

Open simulation dialog    Here you can choose the model to be simulated Choose ‚TR‘ for transient analysis You should choose ‚Euler‘ as Integrator for better performance  You can choose one of three methods for solving nonlinear equation systems    Choose simulation period of 5 ms The ‚Min Stepsize‘ should be shorter than fastest signal changes Make Max Stepsize‘ shorter for accurate results and longer to improve performance Left Click to continue 3
