testing models in HyperStudy fails - error: copy of model rescource failed and solver input file doesn't exist
I have been following the internal example of the Flux environment unter the example tree: co-simulation: multidisciplinary design optimization for electric motors. I have been following the steps of case 2, in which all HyperStudy connectors of each model (FluxMotor, Flux, etc.) are already made and just ready to use.
I made the connection to all inputs and outputs and linked all the connectors. After this I wanted to test the model by clicking on "run definition". I immediately got many different errors messages. What seemed interesting to me was that HyperStudy tries to open files and each time the slash is either a forward or backward slash. As far as I know in python scripts a folder is divided by backward slashes. Could this be the reason why it is not running?
All the files that I have used are attached to this post as a zip. The error log from the console is attached as well.
