EMI_CB_CheckStepAcceptance (EMI Function)

Owning Class: Callbacks

Requires: Control Design and Simulation Module

Prototype

void EMI_CB_CheckStepAcceptance(emiRef model);

Description

Checks whether the current step is acceptable for the simulation. If a step is considered unacceptable, you can use the EMI_CanRejectStep function to determine whether the ordinary differential equation (ODE) solver can reject the current time step. A variable step-size ODE solver can reject a time step if the current step size is greater than the minimum step size. Fixed step-size ODE solvers cannot reject time steps. If you cannot reject the current time step or if you use a fixed step-size ODE solver, you can use the EMI_RequestCallbackToResetStates function to reset states when a step is unacceptable.
