Using an existing executable only makes sense if that was compiled with the compiler option `-DCALCULIX_EXTERNAL_BEHAVIOURS_SUPPORT` (see [this thread](https://calculix.discourse.group/t/implementing-umat-using-shared-library/2441/5) on a similar recent discussion). Otherwise it won’t work. The mentioned thread further recommends to include the additional compiler option `-DCALCULIX_EXTERNAL_BEHAVIOUR_DEBUG` to better understand what is going on.
