@KarlWernersson Thanks for the report. It seems to be running without a crash in our FMU Import and fmusim. I wonder if this is related to directional derivatives. Are you using the directional derivatives that this FMU provides in your import? Does this crash still occur if you don't? Also, does the FMI 2 version of this FMU also result in a crash? Thanks in advance for any additional info.

Hi, I checked again and i had turned on analytical Jacobian for the model translation so directionalDerivative was called, when i turned this of the simulation went well and I didn't have any crash. I tried with FMI 2 and I didn't get any crash with or without directional derivatives.

@KarlWernersson Hi Karl, could you please try the updated FMU CT3_dirderiv.fmu to see if it resolves the issue?
