To calculate the scalar value of the normal velocity on the plane: * Create a new variable (type scalar), e.g. VelNormPlane1 = ( Velocity u * Normal X + Velocity v * Normal Y + Velocity w * Normal Z) * (-1) * Use this new variable for export or display. To calculate the vector of the normal vector on this plane: * Create a new variable (type vector), e.g. VecNormPlane1 * Define its components to: X Component = VelNormPlane1 * Normal X * (-1) Y Component = VelNormPlane1 * Normal Y * (-1) Z Component = VelNormPlane1 * Normal Z * (-1)
