Unable to specify force on the linear torque map powertrain system

Vedant Nande_22140

I am creating a model of a two wheeler with a hub motor on the rear wheel. I wanted to include a simple powertrain system so I imported the linear torque map powertrain from the two wheeler model in the assembly wizard. I have not made any changes except add a force at the rear wheel center, on the wheel body.

I have specified the following expression under the Tz rotational properties of the force: `{sv_torque_output.VARVAL}`, the torque_output is a solver variable prespecified in the imported system.

I am running a straight line acceleration event with transient analysis with Motionsolve, with the Altair driver added.
I am getting the following error:

Can someone please help me solve this problem?
I have checked my model and there is nothing with the ID of 31800100, if that helps.

Hello Vedant

Did you create the entire model using the Assembly wizard or did you just imported a system from the wizard library into your self created model ?

Is it possible to share the model that you have ?

Can you please try using Propulsion Torque once?

Hi praful,

I can share the model with you if you can share your email ID.

I have created the front and rear suspension system by myself from scratch. I have only imported the linear torque map powertrain by using this:

I have exported the linear torque map powertrain from the wizard library.

P.S: I narrowed down to the error in the model being in the powertrain system as the solver runs the npost shaker event without any errors.

How I do define this solver variable? Which expression do I use?
