MARS - A Software Dedicated to Advanced Concrete Modeling

Tetgen and Triangle are called by MARS to make certain types of finite element meshes. They can be found here: http://mars.es3inc.com/protected/MARS/.

Troubleshooting:
1. Make sure download the correct version for your operating system.
2. Make sure they have the correct file attribute (i.e. executable). Go to the directory where Tetgen/Triangle locates, run

Code: Select all

chmod 755 tetgen

and

Code: Select all

chmod 755 triangle

3. Add them to the PATH environment variable so MARS can find them.
