Hello,
I want to plot a linear interpolated data grid to a file
I used "set pm3d interpolate 2,2" to double the points in the mesh interpolating its values.
I want the nodal values of this finer grid in a file
I have a file with the solution of a problem in a 8x8 mesh, for example. I calculate an approximation in a 4x4 mesh. My objective is to calculate and plot the error.
If I could interpolate the 4x4 data in a 8x8 mesh, I could take the difference and plot it as the erro.
Someone can help?
