[petsc-users] TSSolve problems

[Li, Xinya]

Dear Sir,

I am using the ts solver to solve a set of ODE and DAE. The Jacobian matrix is a 1152 *1152 sparse complex matrix.
Each TSStep in TSSolve is taking nearly 1 second. Thus, I need  to improve the speed of TSSolve.
Which parts should be taking into account to accelerate TSSolve?
Thank you very much.
Regards
