Some tips on how to make upgrading Mecway / CCX / Gmsh and other things a bit easier.
These notes are well suited for someone administering to a group of users, but also useful for individuals.


1.  Get latest CCX from dhondt.de site, from a hyperlink simply called "files"

    It will look something like this:  http://www.dhondt.de/calculix_2.20.1_4win.zip 

    Have a bat file to update related softwares. Copy to Public directory, IT/Windows Security won't complain.
    The example below copies CCX, Gmsh into Public directory from a network drive.
     
rem ***** BEGIN sample_update_software.bat 
  
@echo off

 
@echo *****   Updating Calculix Solver                                                          
@echo *****   PASTIX is Default, switch using Library  CCX_custom_commands  PARDISO SOLVER      
c:
cd c:\Users\Public
echo The current directory is %CD% 

mkdir calculix_2.20_4win
cd    calculix_2.20_4win
 
xcopy /E /Y Z:\SOFTWARE\SOFTWARE\calculix_2.20_4win  .
cd ..

@echo *****   Update Gmsh Solver     *****
 
mkdir gmsh-4.10.5-Windows64
cd    gmsh-4.10.5-Windows64
 
xcopy /E /Y Z:\SOFTWARE\SOFTWARE\gmsh-4.10.5-Windows64  .
cd ..
 
pause

rem ***** END sample_update_software.bat 




2. Install latest Mecway, do a "Launch Mecway" and quit

3. Have a bat file to modify the user.config file
   This file is located under the AppData directories, find it with this path: 

   cd C:\Users\%username%\AppData\Local\Mecway_Limited\mec*\20.*  
   
   Make a master.top file from the latest user.config, keeping all lines up the the last </setting> command
   Make a master.bot file of that has the last few lines, it will look like this:
   
          </Mecway.My.MySettings>
        </userSettings>
    </configuration>
   
   
   Make a "user.config sandwich" from the new user.config, with your updates and the user key in the middle:
   
   type master_user_config.top  your_user_config_updates.mid  master_user_config.bot > user.config
   
   Replace the user.config in the same location C:\Users\%username%\AppData\Local\Mecway_Limited\mec*\20.*   
   
    
   Below is an example of customized user.config inputs
   They point to a Mecway_Library, the GMsh and CCX software, a Python Script library, and some DefaultMeshingParameters.
   These will overwrite existing settings above in the master_user_config.top, but everything else will stay the same.

4.  User the Mecway_Library to easily switch solvers (see fig)
