Hi everyone,

Is there a setup which can output displacement boundary and then override the previous displacement boundary file at every time step in Calculix? Please check my file here [GitHub - NUGUY2022/output\_override](https://github.com/NUGUY2022/output_override.git)  
I have a boundary.inp file which give the displacement boundary. I want to output displacement and override displacement data in this file at every time step. Is it possible?
