Hi, Ryan You can specify the size of the images by assigning the render view properties: view size. - renderView1 = GetActiveViewOrCreate('RenderView') renderView1.ViewSize = [600, 557] renderView1.ResetCamera() - Thanks, Yoshimi 2016-09-27 23:10 GMT+09:00 Jamison,

As far as VTK/ParaView are concerned, lines and triangles are just different types of cells. The filters treat each cell uniformly. That is, the gradient filter is treating triangles and lines the same and mixing the results together in the same way as if the data contained triangles and

Hi, everyone, I am new to this list. I like to ask few questions about how to setup a 3D system. Please give me some suggestions if you have experiences. My goal is to let people able to watch the VTK files through Paraview with a 3D glasses on the monitor or TV. So here are the questions:

Hi Ken, thank you for pointing this out! I was not aware that boundary lines are also inifinitely flat cells. This seems true for all boundaries, also the internal boundaries between the two faces. The question for me is now: Is this normal, or does that mean that the whole FEM simulation is

Matthias, If values are being pulled from 7900 units down to 5300 units, there must be some neighbor with lower values. Why that is happening for you I cannot say without looking at your data. Perhaps on the boundary there are some malformed or 2D cells with invalid gradients. -Ken From:

Hi Armin, thank you - thats what i searched for ... Stefan Hi Stefan, IIRC there is a .vtu file containing polyhderal cells in the VTK DATA repository. Otherwise, I attached a .xmf and a .vtu file containing each containing identical data, i.e. 2 hexahedral and 2 polyhderal cell.

Hi Ken, what I don’t understand is that the cell gradients are correct, but their average at the border is not. (Example: All cell gradients adjacent to one node at the border have approx. 7900 units in y direction, the node has approx. 5300) So it seems I cannot determine the gradient in the

You could run the results through the point to cell filter, but that would give you the same answer as the gradient of unstructured dataset filter with the faster approximation option on. -Ken From: "Zenker, Dr. Matthias" Date: Tuesday, September 27, 2016 at 8:28

Hi Kenneth, thank you for the quick answer! So it seems not that trivial to calculate an electrical field between a rod and a plane given the potential… The compute derivatives filter does not give me the problem at the boundary indeed. Instead it gives a value per cell, not per node, which

Matthias, The gradient is estimated with finite differences. Thus, it is not wholly unexpected that there could be differences at the boundaries. However, the algorithm does not assume zero for adjacent cells at the boundaries. The way the unstructured gradient filter works is that it computes

Hi, when I use the gradient filter (unstructured dataset), I observe edge effects which are IMO unphysical. For the nodes on the outer boundary of my domain, the gradient magnitude is smaller than I would expect. The behavior is like the filter tries to use the adjacent nodes to calculate the
