[Paraview] Help: Calculating Vorticity in paraview

[David E DeMarle]

And although there is no button for it, the standard calulcator will
evaluate cross products if you type the expression in manually.

The full list of expressions the calculator knows about are (from
vtkFunctionParser.cxx)
static char funcNames[NUMBFUNCS][10] = {
   "abs(",  "exp(",   "ceil(", "floor(",
   "ln(",   "log10(", "log(",  "sqrt(",
   "sin(",  "sinh(",  "cos(",  "cosh(",
   "tan(",  "tanh(",  "asin(", "acos(",
   "atan(", "min(",   "max(",  "cross(",
   "sign(", "mag(",   "norm(", "if("
};

>> In the calculator, you can see all the components of the vectors (in the

>> Then you should be able to calculate "manually" the cross product.
