Thanks for this modification. Is the trunk r9666 already available somewhere?

Hello,
is it possible to get infromation of the current time step being calculated during the simulation? Or estimate of the simulation time?
It would be very helpful, but I haven't found that functionality so far.
Thanks,
pekka
Hello all,
I have faced a problem with the model Gears. Simulation crashes with an error message:
Simulation execution failed for model: Gears
Assertion failed: current_state.real_buffer_ptr + n < NR_REAL_ELEMENTS, file memory_pool.c, line 101
Can someone give me help with this problem? Is there something missing in the model?
I am working with:
OMEdit - OpenModelica Connection Editor Version: 1.7.0, revision 8711.
Thanks,
pekka
