All,
I have a general question about a structured non-uniform grid. I have set the coordinates X,Y,Z in my code by first calling setUniformGrid and then by setting the coordinates. I have printed out the coordinates and those are as expected. I an non-uniform grid the code will need a specific delta_x delta_y and delta_z since they will differ through out the grid. Does PETSc take a derivative of the coordinates (by default) to get the list of delta’s or do I need to do something specific ? Many Thanks in Advance John
