Hello, I used pygccx library that generates INP file from .geo inpu and .stp model files. When importing INP in prepomax v2.2.0, I have two issues: - the ‘Load\_surf’ surface is not correctly read. - when editing a concentrated load force, it says that one component at least must not be equal to zero, but it’s the case here (see image). ![image](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/9/968759d6f4a45051aa728b15548bc453c9b81365.png) INP file extracts : … \*CLOAD 141981,1,3.0616170e-14 141981,2,5.0000000e+02 … \*SURFACE,NAME=LOAD\_SURF,TYPE=ELEMENT 76045,S1 44530,S1 59809,S1 65714,S1 84939,S1 … ---

The .inp file importer is quite outdated compared to the exporter and mostly supports files generated in PrePoMax’s way. Especially surfaces are causing issues when importing: [Import issues with \*SURFACE - #2 by FEAnalyst](https://prepomax.discourse.group/t/import-issues-with-surface/82/2) ---

I had this before with Aba decks, simply retype the F1 load value, and mag gets recalculated, and not zero. ---

I have fixed this behaviour. The fix will be released in the next version. ---

Does it work now as expected? ---
