Simulink Design Verifier and Solver Configuration not compatible

I want to apply the Design Verifier to my PV system, but the verifier fails during the compatibility check with the following error:

"Translation failed: ['PVSystem_Model_FF/solvConfig']: Reference to non-existent field 'RelativeBuildDir'."

The block "solvConfig" is the Solver Configuration block which is required to be connected to the physical system.

Would welcome any help, thank you in advance!

Hello Philipp,

Please let me know following details.

1. Which version of MATLAB are you using.
2. If you comment out the "Solver Configuration" block & associated downstream constructs, is the issue still reproducible?
3. Is there any parameter named "RelativeBuildDir" used in this block/model anywhere

Best Regards,

Shishir.

Hi,

I have a similar kind of problem.

I am trying to use design verifier to detect design errors in my model with the following outcome:

Building model representation failed: ['Compressor01/Solver Configuration']: Unrecognized field name "RelativeBuildDir".

Solver Configuration is Simulink block that is connected to my gas network. I have not named any field as "RelativeBuildDir" and can not find any field with the name.

1. I am using version 10.3 (R2021a)
2. After solver configuration there is only Reservoir (G)
3. Can not find any parameter named "RelativeBuildDir" but apparently there must be a field with that name.

Hope to hear an answer to this problem!

Hi Saara,

Thank you for your question. We are looking into this, and one of my colleagues will get back to you.

Thanks.

Hello Saara,

Thank you providing the details, this is bug in the SLDV compatability analysis. We have informed our Developers about the same and this would be fixed in the upcoming MATLAB releases. That said, the solver 'Solver Configuration' and 'Reservoir' blocks belong to 'Simscape' library and SLDV does not support blocks from this library. Please find details of supported blocks at this link. Hope this helps.

Best Regards,

Shishir.

Hi,

Thanks a lot for your answer.

That explains the error.
