Hi,
I am doing CFD and at each time step, I need to interpolate values at different points. I'm doing bi-quadratic interpolation and hence to get each interpolated value, I need to solve a 9x9 matrices. There's about 100+ pts and hence 100+ 9x9 matrices to solve per time step.
I'm wondering if it is worthwhile to use PETSc to solve them or am I better off using those direct guassian elimination solvers?
Thanks
