Hello ,i have an issue when it comes to my simulink model.I've made a tranmission model using simscape and simulink blocks.The error is a linear algebra error and also displays an errors to solving an iteration matrix.Any thoughts?

Okay, so the model is a transmission model using simscape and simulink blocks.It includes the engine,Drivetrain and the vehicle body blocks.The error message is as follows"Steady state solve failed to converge.

Nonlinear solver: Linear Algebra error. Failed to solve using iteration matrix."

I've tried changing the initial conditions for the clutch.I've tried changing the solvers and i've also checked my connections.Any suggestions?

If you could upload the model to this question, we could provide a more specific answer. In the screenshots you provided, I do not see any inertia blocks. The most common problem that causes that error to be thrown are nodes with no inertia associated with them.

In Transmission_model/Transmission Subsystem/Clutches and gears, try adding inertias to the lines connected to each Connection port. That maybe enough, or will at least allow the diagnostic to be more specific.
