Supports units (Imperial, SI) and customizable default material. Makes possible to calculate structure in 10 clicks (static, buckling, modal) and prepare the FEA model with groups for other types of calculation.

Don’t use elements with linear approximation! In most cases it can give visually correct but really wrong results (due to very slow convergence)!
Use S6 for shells and C3D10 for bodies! In this case there is no any difference with known commercial programs.
The programs like CalculiX have free system of units. It works like in formulas. For example the displacement of beam is
You can use any units you want, but it should be compatible. For example if you will take “q” in “lb/ft” , you have to take “E” in “lb/ft^2″ , “L” in “ft”, and “J” in “ft^4″.
The result will be in “ft” in this case.
Basically no problem if you will use only SI system – it is most native system for any calculation tasks.
There is very important note about using GMSH and NETGEN with STEP geometry. STEP files have unit features and the opencascade kernel (which used in current builds of GMSH and NETGEN) scale it to meters or millimeters (it is true for current versions). For example you have the detail L=5 inches and you will obtain final mesh with nodal coordinates changed to “127″ or “0.127″ respectively.
Check it every time carefully (“qdis” card ) and scale it if needed, to make your units compatible.
Here is comes… New updated version of lisa-fet ( http://lisa-fet.com/ ) now available for downloading.
Lisa is not open-source software but it has very liberal license (1300nodes for free and $80CAD is not money for this program). It supports open source meshers like GMSH and NETGEN (msh and vol files with groups). This is a good addition to the CalculiX for cross-checking of results (to avoid occasional mistakes and sins). One program is good but two much better (since not too much free and well working solutions for Windows platform at all. Note that most of native linux programs like Elmer, Salome, and even CalculiX, don’t support all functions and features, or have unstable builds for windows. ).
P.S. Some mistakes were found in old bConverged.com version CalculiX_2_5_win_004
see here and here
While installation choose win32 option for calculix 2.5v004 (see here)
New version 2.5 win 005 HERE
Here it cooooomes!
