Problem with initial conditions failed to converge

I'm entirely new to simscape and I am trying to model a simple fan setup. I want to simulate the pressure drop over a pipeline but keep getting this error and don't know what I'm doing wrong:

An error occurred while running the simulation and the simulation was terminated

Caused by:

• ['ventilator/Solver Configuration']: Initial conditions solve failed to converge.
• The model may not give enough information to make it possible to solve for values of some of its variables. Specific advice is given below. all components and nodal across variables involvedCannot solve for one or more variables: 'Fan_G.R.w' (Rotational velocity) 'Ideal_Torque_Source.R.w' (Rotational velocity) 'Ideal_Torque_Source.w' (Angular velocity)

This is the model I have currently built:

I attatched the simulink file.

Dear community, I found the answer myself! I shoul've used an ideal angular velocity source instead of using an ideal torque source.

Kind regards
