FEM

  • FreeCAD generates a input file in Abacus format starts CalculiX (better CCX = CalculiX CrunchiX = The solver of Calculix)
  • FreeCAD reads the results
  • On Linux Processhandling of CCX is missing therefore CCX has to be started manually


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


NSET and CLOAD
  • node set FemConstraintForce which includes a list of nodes
*NSET,NSET=FemConstraintForce

  • First line:
    • *CLOAD
    • Enter any needed parameters and their value.
  • Following line:
    • Node number or node set label.
    • Degree of freedom.
    • Magnitude of the load
*CLOAD
FemConstraintForce,1,0.0
FemConstraintForce,2,0.0

  • Test
    • Line 1042- Line 998 + 1 = 45 nodes * 3333.3333333333335 N = 150000 N
