[petsc-users] Modelica + PETSc?

[Zou, Ling]

This is the website I normally refer to
https://urldefense.us/v3/__https://openmodelica.org/doc/OpenModelicaUsersGuide/latest/solving.html__;!!G_uCfscf7eWS!ZZZIEo4PTP8K3Wn8r3Qk0Zy1YJWCVZtiUVvdSq4KnaeMp3VLcrJ3eQOZocmlvn8MCCGcUyzd0niXGJqTtg4$ 

Looks like DASSL is the default solver.
PS: I was playing with Modelica with some toy problem I have, which solves fine but could not hold on with the steady-state solution for some reason. Maybe I did it wrong, or maybe I am not familiar with the solver. That was the reason of the Modelica+PETSc question since I am quite familiar with PETSc. Also, the combination seems to be a powerful pair.

(Modelica forum or email list seem to be quite dead so asking here.)

I had not heard of it before. I looked at the 3.6 specification, but it did not sy how the generated DAE were solved, or
how to interface packages. Do they have documentation on that?

  Thanks,

    Matt
