Applying Model/Trim Command to a Simulink Model with Bus Objects at Inports/Outports

Hello,

I have a simple Simulink Model called "mdl_w_bus_obj.slx" containing an inport, an Integrator, and an outport. Inport and outport are defined via bus objects.

If I want to trim this model I got the error:

Error using trim_trim_alg (line 162) Model 'mdl_w_bus_obj' contains non-double or complex signals. Cannot set non-double or complex external inputs. Use Data Type Conversions

Obviously, I got the same error if I use the model command:

y = mdl_w_bus_obj(t0, x0, u0, 'outputs')

Without the bus definitions at inport and outport the trim routine works fine.

Is there a Workaround? Actually, I dont want to modify the model. Hopefully, attaching the model to this post works.

All the best and thanks for any answer,

Florian
