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. -Ling From: Matthew Knepley <[email protected]> Date: Monday, June 24, 2024 at 6:12 AM To: Zou, Ling <[email protected]> Cc: [email protected] <[email protected]> Subject: Re: [petsc-users] Modelica + PETSc?

(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?
