Hi there, I am using linux version of paraview to read .vtk data files. (Anyone knows if I can attach documents in this mail list?) I have two questions:
1) Volume calculation: I found that the "integrate variables" over a sphere clip never gives the correct volume. For example, I tried to use a very simple geometry and a very fine mesh (a 200x200x200 micron cube with 2 micron cube elements), and use paraview to generate a sphere clip that has radius of 50 micron in the center of that cube, then I apply the "integrate variables" filter to the clip and show the "Cell Data", it gives a volume of 4.78818e-13 instead of 5.236e-13, which is 4/3*pi*r^3. The discrepancy is so large that it just cannot be due to the coarseness of the mesh. Different mesh and different size of clips gives different discrepancies, and I cannot find any obvious relationship between the paraview-calculated volume and the real volume. 2) X-Y plot: how can I do a xyplot of a scalar along a curved line? For example, if I have the pressure field data from a flow-around-a-cylinder case, I want to plot the pressure along the surface of the cylinder as a function of angle or arc length. 3) tensor calculation: I have the pressure field and velocity field calculated from a CFD tool (Transat in my case), how do I calculate stress tensors at each point from P V field in paraview? I am new to paraview and this mail list, please let me know if I asked any inappropriate questions. Thanks in advance for your kind help.
