Stephen, By averaging, are you trying to compute the lift/drag forces? If so, do the following:
1) Generate Surface Normals (requires vtkPolyData as input, so you may have to use Extract Surface first) 2) Multiply it by your pressure variable using the Calculator. 3) You can then integrate up using Integrate Variables to get the pressure force in the x, y, and z directions (this includes the face area). If you are doing this for a 2D line, make sure to do items 1) and 2) first before taking your slice and applying 3).

Can this be done in ParaView 3.8.0? Hope my question is clear, Stephen p.s. Presently I do a slice in the z-direction followed by a "plot over sorted lines" to get the surface pressure coefficient. -- [email protected] 2004 route des lucioles - BP93 Sophia Antipolis 06902 CEDEX Tel: 04 92 38 50 54 Fax: 04 97 15 53 51 ********************************************************************** This email contains information that is private and confidential and is intended only for the addressee.
