[petsc-users] Trying to modify petrbf to use custom text file

[Anil .]

Hi,

I have a text file containing N rows.
Each row with x,y,omega values.
I am trying to interpolate this data onto a regular grid using petrbf
But the KSP does not converge and am not able to find the reason.

The code is available with the text files at
https://www.dropbox.com/s/cypuwugbxo07kx0/rbf-interpolation.tar.gz

I am very new to petsc and any direction how o proceed would be helpful.
