Hi,

I am facing problems with simulating the subject example. In OMEdit, the instantiation and compilation go successfully, however, at the simulation output I receive the following errors.
__
Failed to solve linear system of equations (no. 6971) at time 577.447282, system is singular for U[3, 3].
The default linear solver fails, the fallback solver with total pivoting is started at time 577.447282. That might raise performance issues, for more information use -lv LOG_LS.
Matrix singular!
under-determined linear system not solvable!
While solving non-linear system an assertion failed at time 577.447.

Also, when I edit any parameter, I get compilation errors and the simulation doesn't proceed.

Could you please tell me about the effects of those errors at the simulation output and why I am unable to edit any of the parameters??


Please note: I have made a duplicate model of the subject model with a different name and I am using OpenModelica1.13.264bit.

Thanking you.
