FEM

  • FreeCAD erstellt eine Eingabedatei im Abacusdateiformat und startet CalculiX (oder besser CCX = CalculiX CrunchiX = Der solver von Calculix)
  • Unter Linux fehlt das Prozesshandling und deshalb muss CCX manuell gestartet werden.


Windows
  • Installed vConverged Calculix Pachage which includes CCX (Solver), CGX (graphical Pre- and Postprocessor) SciTE (Editor with Syntaxhighlighting and Integration for making an analysis or start CGX)
  • Includes WindowsHelpFile of the official Manual --> C:\Program Files (x86)\bConverged\common\help\bConverged.chm
  • SciTE --> load the *.inp file --> Tools --> Solve
  • Compare the results with FreeCAD (compare the textfiles) --> Yeah they are nearly identical !!!
  • Path in Windows is shown in FreeCAD --> C:\Users\bhb\AppData\Local\Temp\FreeCAD_Doc_SOMEREALLYWILDNUMBER\FemAnl_c6c0
