I'm trying to simulate the effects of cable sizing on a diesel generator output but I get the following error (note solve is ode23t):
An error occurred during simulation and the simulation was stopped
Caused by:
['DieselGenerator/Solver Configuration']: Initial conditions solve failed to converge.
Nonlinear solver: Linear Algebra error. Failed to solve using iteration matrix.
Problems possible for transient initialization, as well as stepsize control for transient solve, due to equations of one or more components:
