How to Extract and Plot Elastic Strain Data Along a Specified Path？

[kight55]

I would like to extract the elastic strain data along a specific path (x=0.5,y=0.5) and plot the distribution of elastic strain along the path (as shown in Figure b). Is there an appropriate method to extract the elastic strain values along the path?

There is no direct way (in Neper or FEPX) at the moment.

However, with Neper, you can do it by creating a position file with the position of points along the line segment, loading that position file in -M and extracting the element to which each point belongs:

neper -M myfile.tess -loadmesh myfile.msh -loadpoint mypositionfile.txt -statpoint elt

To work on a deformed mesh, you can use -transform "node(<file_name>)".

Then, from the point positions and the elemental values (of the elastic strain), you can easily generate the profile.

Thank you very much, the answer is very helpful!
