I want to set my models simulation stop time from an m file, but I'm a little confused about how to go about it. When I'd get the data for blocks I'd use get_param, but I want to get the parameters of the model. Would I go about it the same way? Thanks.

You can set_param for the model also:
set_param('modelname', 'StopTime', '3000')

If you are using the sim function to run your model, you can set the stop time as follows,
sim('model_name', 'StopTime', '40');

Thank you but how to set this dynamically from a parameter instead of a constant value?

You can also do it by passing it as an argument when you run the simulation from the m file:
sim_out = sim(sim_model, t_stop)

Hmm. Not sure. Are you converting t_stop to a string? This is the exact statement I am using right now with MATLAB v2021b. Maybe you need to include the option char array like this:
sim_out = sim(sim_model, 'StartTime', '0', 'StopTime', string(t(end)));

Actually, the original code I posted above where t_stop is a number does also work in 2021b. Maybe this behaviour has been removed in recent versions. Nevertheless, maybe it's best to always include 'StopTime' and use string(t_stop).
