Hi Umut - Do you mean that you cannot select an appropriate value? (By
sliding the mouse? You can just type in numbers manually...)

To apply the same options to many views at once, select the appropriate
"link" in Tools->Options->Post-pro.

Attached is a script that gives nice results on your dataset:

gmsh fus.opt fuselageRst.msh

Using demo/anim.script with these options creates the following movie:

This is because you have line elements in your mesh, so Gmsh also
displays the solution on these. Applying a "normal raise" on lines is a
bit special, since the normal is not uniquely defined for lines.

Two solutions: 1) apply the raise in a specific direction, or 2) just
don't draw the lines ("View.DrawLines = 0;" in the attached script).
