Selecting single result node for local results

Post by Aleks »

I want to read the results of individual nodes. How can I do that?

I use this method:
1. File "Export", export FEM result as vtk-file
2. open Paraview, load vtk
3. Activate "Hover points on"
4. Move cursor over body, stop, result window opens (do not click, simply move the cursor)

Thank you. I will use it like this then.

It would be useful if one could directly select nodes in FreeCAD. Do you know if anyone is working on that feature specifically?

In CalculiX you can add the following line to write history output for a given element/node set to .dat file:

- elemental variables:

*EL PRINT, ELSET=...
variable_index

- nodal variables:

*NODE PRINT, NSET=...
variable_index

This option (along with set creation) is not yet supported so you would have to export the input file from FreeCAD, modify it and run the analysis with ccx solver using the command line.
