Hello,

Very boring question, but tearing my hair out over it.

How to I get axial force values out of beams and trusses? I need to post-process the figures, so need them in the .dat from \*Node Print. Section forces seems to be nearly there, but I can’t work out how to get them out of the .frd file.

Thanks

With `*NODE PRINT`, you can get the applied and reaction forces from nodes. You can also use:

```auto
*EL FILE, SECTION FORCES, OUTPUT=2D
S, NOE

```

Or try `*SECTION PRINT`, but it needs a surface and this can be tricky for 1D elements:
