Being able to switch to Kelvins would be nice. It was requested in the past: [Unit Systems: (m, kg, s, K) and/or (mm, kg, s, K)](https://prepomax.discourse.group/t/unit-systems-m-kg-s-k-and-or-mm-kg-s-k/1032)

You can use 1D (e.g. beam) elements in CalculiX for heat transfer but they are expanded to solids anyway and not supported in PrePoMax for now.
