what is

[GeoGroup]

Dear Dr. Anitescu:

What is the difference between example PlateWithHole andPlateWithHole_DEM. Would you please add some illustration for PlateWithHole.py

The files containing _DEM implement the energy minimization method, while the ones without "_DEM" implement the baseline model (PINN). The PlateWithHole examples deal with the Kirsch benchmark problem in linear elasticity, described for example here: https://www.fracturemechanics.org/hole.html
