This package contains CalculiX 2.22 binaries for ccx and cgx and the
cad converters for windows originally written by Pascal Mossier
and tetgen and glut. 
The source codes are included in http://www.dhondt.de/ccx_2.22.src.tar.bz2
The source codes are included in http://www.dhondt.de/cgx_2.22.all.tar.bz2
and http://www.dhondt.de/cgxCadTools.tar.bz2
 
They may be used as they are but they are also well suited to replace the 
now outdated binaries in the "bConverged CalculiX for Windows" suite.
(REMARK about the manuals: The user may use the ones from the
CalculiX web side. Be aware that you may re-define the browser and locations
using the .cgx file to make them accessible from cgx via the help menu. Please
consult the cgx manual on how to do that (see Customization).) 

The binaries were provided by:
rafal.brzegowy@yahoo.com
Many thanks!

For stand alone use:

Place the binaries together with the dll's in a location were the system will
find them (the location has to be in the search path).

For use with the "bConverged CalculiX for Windows" suite:

1)
Rename cgx.exe of bconverged in
C:\Program Files (x86)\bConverged\CalculiX\cgx\cgx.exe
to cgx_bconverged.exe
Move the desired cgx_xx.exe to that location and rename it to cgx.exe

2)
Place there also the glut64.dll

3)
For ccx_dynamic.exe you need to install the library mkl_rt.2.dll which is not
included in this package

The optional user specific ".cgx" configuration file is expected in the
personal home directory. This directory will be listed in the terminal after
start-up. It is determined by combining the environment variables "HOMEDRIVE"
and "HOMEPATH".

3)
Rename ccx.exe of bconverged in
C:\Program Files (x86)\bConverged\CalculiX\ccx\ccx.exe
to ccx_bconverged.exe
Move the desired ccx_xx.exe to that location and rename it to ccx.exe

Remarks concerning ccx from Rafal Brzegowy:

ccx_dynamic.exe = spooles (static), pastix (static), pardiso (dynamic),
                  requires one API MKL library
ccx_static.exe = spooles (static), pastix (static)

Switch pardiso link from dynamic to "Single Dynamic Library", description:

Base description (http://portal.nacad.ufrj.br/online/intel/mkl/common/mkl_userguide/GUID-7091CAB6-0506-443A-ABA0-CCE2245A1A1C.htm):
You can simplify your link line through the use of the Intel MKL Single Dynamic
Library (SDL).
To use SDL, place libmkl_rt.so on your link line. For example:
icс application.c -lmkl_rt
SDL enables you to select the interface and threading library for Intel MKL at
run time. By default, linking with SDL provides:
Intel LP64 interface on systems based on the Intel® 64 architectureIntel
interface on systems based on the IA-32 architectureIntel threading

Best regards Rafal


Remarks concerning cgxCadTools:

The cgx distribution includes a step file which can be used to check the
installation.
It is included in
<your install path>/CalculiX/cgx_2.22/examples/cad/halter.stp

To invoke the converter:
Since OPEN CASCADE needs libstdc++-6.dll (64bit) it is necessary to install
mingw:
https://sourceforge.net/projects/mingw-w64/
Then you need to install the OPEN CASCADE Technology 7.4.0 libraries, either
from:
https://www.opencascade.com/content/latest-release
Or you search the internet for "Download Open CASCADE Technology 7.4.0".
Or Install opencascade package: $ pacman -S mingw-w64-x86_64-opencascade

Then you start the converter:
cad2fbd <your install path>/CalculiX/cgx_2.19/examples/cad/halter.stp
writes: result.fbd

The model can be meshed with the following commands (ignore the errors!):
cgx -a result.fbd
mesh all
# optionally use 'qmsh' to modify the surface mesh (see the manual) then
mesh all tet
plot e all

Some additional remarks from Rafal Brzegowy concerning the compilation of the
cgxCadTools:

1. Add to mingw(msys) prebuild package:
   $ pacman -S mingw-w64-x86_64-opencascade
If you want build in Windows, you need to do:
1. Instal msys2/mingw
2. Instal base packages: $ pacman -S mingw-w64-x86_64-toolchain
3. Install opencascade package: $ pacman -S mingw-w64-x86_64-opencascade
4. Copy my makefile in to the correct src folder, like:
   Makefile_cad2fbd to cgxCadTools/CadReader/src
5. Make: make -f Makefile_cad2fbd, make -f Makefile_fbd2cad
