Hi,
When compiling a big model within OpenModelica, I obtained the error message
below :
" Error: Model is structurally singular, error found sorting equations
............"
The error message listed also a number of equations and their related
variables. The model is not singular since it runs correctly under Dymola.
Did this mean that the omc (DAELow module precisely) can't perform BLT sorting
or index reduction for this model due to its complexity?
As indication, the model have 1200 variables, 385 Unknowns and 53 continuous
time states. The same model runs correctly on Dymola and it contains 3
numerical Jacobians.
Thank you in advance.
Regards,
Hassen
