Hello,
I’m using a Face Cubic Centered (FCC) distribution point instead of the usual Cubic distribution. But, when I plot an isosurface (Contour), it doesn’t look good.
At first, for each (i,j,k) I’m using the following expressions for generating the mesh points:
x1 = i; y1 = j; z1 = k
x2 = i+0.5; y2 = j+0.5; z2 = k
x3 = i; y3 = j+0.5; z3 = k+0.5
x4 = i+0.5; y4 = j; z4 = k+0.5
So I have four points for each (i,j,k).
Secondly, I generated the vtk file using ni the number of cells associated to the index i and the same for nj and nk (with a STRUCTURED_GRID):
…
DATASET STRUCTURED_GRID
DIMENSIONS ni,nj,nk
POINTS 4*(ni)*(nj)*(nk) float
…
The distribution point looks well when I use the paraview. However, as I mentioned before the isosurface doesn’t look good. I have been read about it and I found that is related with the number of cells (ni*nj*nk), isn’t it?
Finally, I also tried to associate one (i,j,k) for each point in order to increase the number of cells. The contour looks better with this, but it doesn’t work at all.
So, do you know if there is some way to generate the vtk file? Do I need to use an UNSTRUCTURED_GRID?
Many thanks,
