(Journal: Archive of Mechanical Engineering, ISSN 0004-0738, e-ISSN 2300-1895, Polish Academy of Sciences, Committee on Machine Building)

The cycloidal gearbox model was described in the article:
"MULTIBODY DYNAMICS MODEL OF THE CYCLOIDAL GEARBOX, IMPLEMENTED IN FORTRAN 
FOR ANALYSIS OF THE DYNAMIC PARAMETERS INFLUENCED BY THE 
BACKLASH AS A DESIGN TOLERANCE"
Authors: Roman Król, Kazimierz Król
Journal: Acta Mechanica et automatica, ISSN 1898-4088

The purpose of the given software for the cycloidal gearbox analysis
is the presentation of results in the scientific article.

The Author does not give any warranty for the software.

Usage of the results visualization software:

1) Compile the analysis software using compile.bat under Windows operating system.

For compilation, the GNU Fortran compiler gfortran.exe is required.

2) Run cnmain.exe with analysis length 0.6 and the step size 1e-5

3) Place myforcesresults.txt and myresults.txt in the same folder with VisualizationApp.exe

4) Edit the MATRIX_SIZE.txt, it should contain the number of the rows in the myresults.txt file

5) Run the VisualizationApp.exe, the glew32.dll should be in the same folder.
