[Gmsh] sweeping through a mode shape view

[jean pierre aubry]

hello

when i do a modal analysis in Code_Aster, with, let's say, 20 modes
saved in a med file 
in Gmsh for every single calculated mode i can only
see the maximum deformed shape for each mode 
is it possible to show on the screen an animation for each mode (with a
sin function maybe) 
i admit it is mostly useful to show to the customer, but!

the sweep button at the bottom of the screen will sweep thru the 20
calculated mode max values which is meaningless

is that possible ?
