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

Hello Adam,
I am using motionview 2024.1 and i have switched the solvermode to adams. I have also connected the adams solver to motionview. So i am trying to run the adams simulation from inside motionview directly. The model was created in Motionview using the default library entities.
I had made update to the preferences_mbd.mvw and the pc_run_adams.bat files and am able to submit job to adam solver directly from inside MV
Altair EmployeeHi @Karthikeyan,
Excellent! I'm glad you were able to reach a resolution for your issue.
Thanks,

Sorry, may be my response was unclear. I only tried to clarify to your earlier query about the MV version and how i had setup the adams to MV connection. The issues that i listed were observed with Motionview 2024.1 and with Adams was linked to MV
Can you suggest what more needs to be done?
Hello Adam, my issue is not resolved. May be you might have misunderstood my response. Can you suggest a solution for the issues that i face?
Altair EmployeeHi @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,

Okay, thanks Adam

Hi @Karthikeyan,
Are you trying to use the Adams solver option within an older version of MotionView (below) or are you exporting the model and trying to run it within an Adams/View session?
The msautoutils, or MotionSolve Automotive Utilities subroutine, will be used for entities like tires and the driver model. If you are trying to use this model within Adams/View, then you will likely need to replace those entities with Adams-specific automotive entities, or just simply solve the model using MotionSolve.
Hope this helps!
