[petsc-users] Error configuring PETSc with SUNDIALS (to solve stiff PDE)

[namu patel]

Hello All,

I was trying to configure PETSc with SUNDIALS so that I may use PVODE to
solve a stiff hyperbolic PDE of the form

A(x) u_tt = K [B(x) u_x - F(x, u, u_x, t)]_x ,  t > 0,  0 < x < L ,
u_x(0, t) = u_x(L, t) = 0 ,
u(x, 0) = u_t(x, 0) = 0 ,

where K >> 1. I was reading around to see what may be a good numerical
implementation for such a problem and it can be tricky here because the
stiffness is both in the linear part and the nonlinear forcing term.

I want to try PVODE availble in the SUNDIALS package. When I try to
configure PETSc with SUNDIALS, I get the message:

Downloaded sundials could not be used. Please check install in
/Users/namupatel/Softwares/PETSc/3.6.2/linux-dbg

Two questions:

1. How can I resolve the above error?

2. Are there any recommendations to solving the stiff PDE stated above so
that I can experiment to see what may be an efficient implementation?

Thank you,

Namu
