All, I have two code baseline one uses a standard 7 point STAR stencil the other a 13 point Star stencil.
The first baseline works the second comes back with errors MatSetValuesStencil Argument out of range In the second baseline I have a fourth order 13 point stencil which spans +- 2 in all direction from each 3D point of my data set. stw = 2 I set the width in DMDACreate3d( ....dof,stw, 0, 0, 0, &da) Does a larger stencil need to be quantified or declare in another location?
