Extracting results along line or surface

[Ehsan]

Hello,

I solved a problem by deal ii in 2D and 3D and calculated displacements and stressed.
I use VisIt to visualize the displacement and stress outputs in the hole domain.

Now I have problem extracting data, and I would appreciate it if someone helps me.
In a 2D/3D problem, I want to extract and plot results (e.g. displacements or stresses) along a Line/Surface (straight or curved).

It is not important for me, how to do it, using deal ii or VisIt . I mean if extracting these data using VisIt features need less effort it is also ok for me.

Thanks.
Ehsan

Hi Ehsan,

I don't use Visit, but Paraview has the functionality to plot a solution over a curve. Have you looked at the Visit tutorials for information as to how you might to this in Visit? Looking at this one, I think that the feature that you are be looking for might be called Lineout.
