[Paraview] PV 3.10.1 integration over a surface
How does one compute the integral of P Normal ds ? where Normal is the surface normal vector click on integrate variables computes the integral of P ds I would like Fx = integral of P nx ds where nx ds is the surface area normal to the x-direction. Hope my question is clear. Stephen p.s.

Re: [Paraview] PV 3.10.1 integration over a surface
One way is to use the calculator filter to multiply the pressure by the normal to get force per unit area on the cylinder. Then you can use the integrate variables filter to get the total force on it. If you don't have normals on your cylinder, you can use the generate surface normals filter but that only works for polydata. The extract surface should get you from any other data set to the polydata you want.

[Paraview] FW: Coloured isosurfaces when running MPI
Dear forum, I am using Paraview to visualise a large dataset coming from a direct simulation of turbulence (size of the original data of order 10-100GB). Naturally, I am running in parallel on a cluster (using the mesa), which also works very well. However, there is one issue: I want to visualise isosurfaces of a quantity, and colour them using another scalar quantity. When running serial, everything is fine. When using multiple processors with MPI leading to the data being distributed, the rendering of the isosurfaces is still ok. However, the colouring seems to be based on the scalar field of the first data segment (i.e. the first processor) only. This then leads to very visible boundaries between the processors as the colours are clearly not correct (see example on http://www.mech.kth.se/~pschlatt/files/resampled.jpg). Again, running on a single processor everything is correct, and running on different numbers of processors will shift the edges. This issue could be confirmed in all version up to 3.10. Due to this, I am required to run in serial, which is very painful both due to memory requirements and very long rendering times (up to 15 minutes for a single frame). Thus, if there would be a simple fix, I'd be very interested. Thanks a lot in advance for any hint.

Re: [Paraview] PV 3.10.1 integration over a surface
I think the cell normals that you have are generated for visualization and not really part of your data set that's directly outputted from your filter. So when you do cell data to point data you still don't have the normals in there. Did you try using the extract surface and generate surface normals filters?

Re: [Paraview] PV 3.10.1 integration over a surface
Hi, my understanding is that when you used CellDataToPointData filter, the cell data are removed and thus they don't appear in the Calculator. The CellDataToPointData filter has a Pass Cell Data option that will keep the original data in the pipeline. However, I didn't understand from where you got your normals: are they generated from Generate Surface Normals filter or outside ParaView? When you load your data, do you see the CellData array in the information tab of your data? Best regards, Jerome 2011/6/19 Andy Bauer andy.ba...@kitware.com I think the cell normals that you have are generated for visualization and not really part of your data set that's directly outputted from your filter.
