hello

can you be more precise ? do you have a code to share ?

You can connect all input variables with the input block including model variables. After that, you can connect the Simulink inputs to the workspace using Data Import/Export screen in the configuration parameters. You can create an input vector with respect to time and Simulink updates the input vector using the time variable.

You can use the set_param function to change the value of each block during the simulation. However, it is really hard to make changes with respect to time. You need to add some extra logic, and Matlab functions in your Simulink file.
