Hi,I think I did found an inconsistency in the component order in the compute derivative filter.
The web page http://www.vtk.org/doc/release/4.0/html/classvtkHexahedron.html#a16 said
Compute derivatives given cell...On the other hand, if computing derivatives of velocity (vx,vy,vz) dim=3, 24 values are supplied ((vx,vy,vz)1, (vx,vy,vz)2, ....()8), and 9 deriv values are returned*((d(vx)/dx),(d(vx)/dy),(d(vx)/dz), (d(vy)/dx),(d(vy)/dy), (d(vy)/dz), (d(vz)/dx),(d(vz)/dy),(d(vz)/dz)).*
I created a simple test to verified the order (file attached), with 9 vectorial fields that after the Compute Derivative will generate a tensor full of zeros but with one component equal to one.
for exampleIf we follow the documentation the field dxdy must generate a tensor with the terms
0 1 0 0 0 0 0 0 0 but paraview gives 0 0 0 1 0 0 0 0 0 can any one confirm this??? working with paraview 3.14.1 64bit Linux Thanks -- Felipe Bordeu Weldt Ingénieur de Recherche ------------------------------------- Tél. : 33 (0)2 40 37 16 57 Fax. : 33 (0)2 40 74 74 06 [email protected] Institut GeM - UMR CNRS 6183 École Centrale Nantes 1 Rue de La Noë, 44321 Nantes, FRANCE -------------------------------------
