Does ParaView support .facet files? There appears to be one in VTK, some documentation suggests it should be there (http://www.vtk.org/Wiki/ParaView:FAQ), but ParaView does not seem to load them. -Ken From: Micah North micah.no...@matrixresearch.commailto:micah.no...@matrixresearch.com Date:

None of those. The cell data to point data filter just finds all cells neighboring each point and averages the cell values of those neighbors. -Ken On 10/18/11 8:26 AM, Stephen Wornom stephen.wor...@inria.fr wrote: How does PV go from cell data to point data? Linear interpolation? or

and the best solution depends on your data semantics and problem domain. Although simple averaging is not always ideal, it is fast and can be used as a low order approximation as well as anything else. -Ken On 10/18/11 8:45 AM, Stephen Wornom stephen.wor...@inria.fr wrote: Moreland, Kenneth wrote

I should probably let someone who knows the implementation better answer this, but I'm going to go ahead and take a crack at it anyway. The reason why it works for the writer but not the animation is because they are grabbing the values from different places. The writer (I think) implements

You can use the has mode shape function to write multiple mode shapes to the same exodus file. You could identify the frequency using the time. It's a logical use for it, but ParaView won't do anything with that other than print it in a label. The automatic mode shape animation supported by

Short answer, no. If your surface is convex, you could threshold the surface elements you need by first running the extract surface filter, then generating cell normals, then using the calculator to extract the x component of the cell normals, then thresholding all cells with the x component of

Try applying the Generate Ids filter and then color the result by the Ids cell field (not the point field). The colors won't exactly be arbitrary, but if you switch to the rainbow color map you'll get something fairly close. -Ken On 1/5/12 8:43 AM, Rafa x rromero3...@gmail.com wrote: Dear

Re: [Paraview] [EXTERNAL] PV 3.12.0 Is it possible to extract a contour?

2012-01-09 Thread Moreland, Kenneth
I don't really understand the question (or rather, what you are trying to achieve with extract surface, connectivity, threshold, and contour), but the most common reason for the contour filter being unavailable is that you do not have any point data. The contour filter does not work on cell data.

I believe this change is intentional. When you run the clip filter, it turns the data set into an unstructured grid. The unstructured version of contour always computes scalars, so that checkbox has no effect. To demonstrate that the checkbox has no effect, it is now grayed out. -Ken On

Do you mean color a surface by a scalar field? (The example you give does not have contours as far as I can see.) If so, simply select the field in the color by combo box (second toolbar, leftmost combo box). More details are given in the ParaView tutorial

This all depends on the structure of your netCDF file. NetCDF is a general format that stores some set of named multidimensional arrays with attributes. Generally when you write a netCDF file you need to follow some convention that provides semantic meaning to these arrays. Given no other
