Error while running motionview exported model in Adams

Description: [Porting Motionsolve subroutines to Adams]

Product/Topic Name : Motionview

Hi, 

I have a vehicle model built in motionview that I would like to solve with Adams solver. I had exported out the acf, adm files and was able to submit the job to adams. 

However, there are some outputs which require subroutines which are specific for Motionsolve. I get the following error
"Encountered error "The user library "msautoutils" could not be located"

I copied the msautoutils.dll to the same directory as the simulation input files after which this error disappeared. But i got a new error
"ERROR: Unable to establish AccessFunction connection, please set NUSOL_DLL_DIR" 

I added a new environment variable named NUSOL_DLL_DIR along with the equivalent path

After this the simulation starts but exits without any further message. 

Also, in the adm file, i see that msautoutils subroutine is being called instead of equivalent relevant adams subroutine. I would like to understand why motionsolve subroutine is being called while exporting the model to Adams.

I would like to know how to port the Altair subroutines to Adams correctly. Could you guide me with the process? 

Regards

Karthikeyan

    Hi @Karthikeyan,

    As stated earlier, the issue may lie with the fact that you are trying to use the ADAMS solver for MotionSolve only entities, like the tires and driver model. As a test, I would suggest that you create a simple model that does not use the msautoutils subroutine, such as a spring-mass-damper model, and try your MotionView-ADAMS coupled simulation to see if it completes. Assuming it does, you will possibly not be able to couple this type of analysis with these automotive entities.

    Thanks,
