Paravis Plot over line with Shells (Coque 3D)

Hey

i already ask in the german section of the caelinux forum and in the code aster forum.
i hope someone here has a solution for my problem.

i have a problem with my postprocessing (paravis in salome). i have to compare different models (Solids and Shells).
i used Plot over line to get the displacement on a path over the complete model (bending line) and on the same path the stresses (VMIS).
with the Solid model it's working fine but for the shell there is a colormap contour plot but no data in the plot over line.

the shell is Coque 3D with tria 7 elements.

is there any solution for my problem?

thanks in advance
