Failed to export velocity in ensight-gold format
 

I did a simulation and showed the result velocity field, which looked fine. Then I exported the pressure and velocity, and change the ".encas" into ".case" so that it can be shown in Paraview. However, only the pressure can be shown, while the data about velocity, including the contour of velocity-magnitude and vector field of velocity, always lost. How can I fix this?

well I figured out the problem. The mesh I used only have one thin layer in 3D, which leads to no sample point in output file.
