[petsc-users] PETSc DAE solver

[Jin, Shuangshuang]

Shri, thank you! That's very helpful information. I'm going to obtain the development version of PETSc now.

Thanks,
Shuangshuang

Jin,
   If you are working on integrating power grid DAE equations  then you should use petsc-dev instead as we've added an example for it. petsc-dev/src/ts/examples/tutorials/power_grid/stabiltiy_9bus/ex9bus.c. There are other examples in the power_grid directory.

Hi, I'm trying to use PETSc to solve a set of first-order differential and algebraic equations such as:
x' =  f(x,y)
0 = g(x,y)

The resources I can find online so far are

 1.  PETSc Manual: Chapter 6 TS: Scalable ODE and DAE Solvers
 2.  petsc-3.3-p6/src/ts/examples/tutorials
which still seems  vague to me at this moment.

Can anyone tell me if there's any more specific references I can refer to as a starting point to tackle this problem?

Thanks,
Shuangshuang
