error in electric vehicle simulation in Simulink

Minimum step size (2.0) is larger than discrete sampling period (0.5)

Component:Simulink | Category:Model error

I tried running a model in simulink and this is what it keeps showing. Are there any suggestions on how i can increasing the discrete sampling period.

Press Ctrl+E to bring up the configuration parameters, Solver, set the Minimum step size from 2.0 to at least 0.5, or better at 0.1.

but thats the issue if the minimum step size is .1 the simulations runs really slow

First you need to set the model correctly and run simulation. Then you can talk about fast or slow simulation speed.

If there is no other constraint, you could change the discrete sample time from 0.5 to something larger, for example 2.0. Then you could make the mininum step size to be the same as that discrete sample time. It will run and it probably will be faster.

You need to find the blocks that determines the 0.5 discrete sample time to change it.
