nested FMU: Access violation #168

I have a model that imports an FMU and want to export it as FMU. The export (with FMIKit2.8 alpha2) works fine, but when I try to simulate the FMU it crashes with an access violation.

Example will be sent by mail.

The problem seems to be that the path for the binary of the nested FMU is still pointing to an absolute path. This error is reported via ssSetErrorStatus() but it's not forwarded to the parent FMU.

As a workaround you can keep the unzip directory of the nested FMU (or create it on the target machine), so the S-function can use the hard-coded path.

Hello, I am facing a similar access violation issue when tried to import and simulate the nested FMU in Simulink. Please find the attachment of my sample trial.
