If you have successfully installed IBG, you can try out the examples.
There are different examples, try
make
for the actual list of these examples. Remark that some of them are 3D test examples which will not work in the 2D version, but require the complete 3D version.
Se more information for some of the examples:
All these test examples create a binary in the subdirectory ibg/bin named ibg. They write the resulting grid into the subdirectory ibg/test. The grid is written in a simple Simplex Grid Format.
For the 3D examples, the grid generator creates a 3D grid, but usually only the surface grid will be written out. You can change this easily.
There will be some informational messages on your standard output about the grid generation process.
