Hyperstudy

I started with the hyperstudy example provided among the 2D examples. However, when I try to run the definition, I consistently receive an error. The test is unable to write, execute, or extract, and I'm unsure why.

below is the nature of the error message i am getting:

755 Error : Failed to copy model resource ( C:/Users/gordon_asante1/hyperstudy/MDO_EMOTOR_STUDY/MDO_EMOTOR_Case2/HyperStudy/1_FluxMotor/Connector_FM_Hst/Connector_FM_Hst ) to ( C:/Users/gordon_asante1/hyperstudy/MDO_EMOTOR_STUDY/MDO_EMOTOR_Case2/HyperStudy/approaches/setup_1-def/run__00001/m_1/Connector_FM_Hst ) with error ( The system cannot find the path specified

749 Error : Failed evaluating expression ( r_8 ) with error ( Failed evaluating ( Base speed::Control angle (deg) ( r_8 ) ) ) in ( CTRL_ANGLE ( var_23 ) ).

Thank you in advance for your support!

Hi @Acheamp,

It looks like you may be encountering two separate errors: a file path that is too long and an invalid expression.

I would suggest you move the Study temporarily to a higher location, like your desktop, and trying the definition again to test to see if the 755 Error code disappears.

I would also review the expression you are attempting to use for the response r_8 and check for any errors to clear the 749 Error.

Hope this helps!

Hi Adam,
Thank you so much for your response. I have taken all the recommended steps.
After relocating the study to a shorter path, everything appears to be working so far. However, after changing the simulation file location, the simulation has been running for quite a long time.
In fact, the first attempt ran for over 7 hours before I ended it manually. I am now trying again with just one job to see how it goes, but I was wondering: is it normal for it to take this long?

find below feedback from currunt definition run:
