i need a step by step guide on building a model that used variable step solver. I have erros like ode45 not found using rtw. Thanks

None of the ode solvers are supported by RTW. You would need to create your own solver, which is difficult to get right and is unlikely to operate in "real time".

As stated on this page:
If you plan to generate code from your model and run the code on a real-time computer system, choose a fixed-step solver to simulate the model because you cannot map the variable-step size to the real-time clock.
