Good morning,

I am reading the golden rules of the Calculix model, and would like to know in which point of the input file I have to include this commnad:

In which point of my .inp file do I include it?

Thank you very much!

In the `*NODE FILE` keyword (the one used to write displacements and other nodal outputs to .frd file with results) within the `*STEP` definition (usually almost right before `*END STEP` since output requests are typically the last part of a step definition).

However I cannot see the 3D version, that is why I asked, because I think I am doing something wrong

You have to add it to the keyword, not data line:

```auto
*NODE FILE, OUTPUT=3D
RF, U

```

Oh okay! I didn’t know the difference between keyword and data line!  
Thank you very much @Calc_em
