i have a very large mesh with lots of Delauney criterion violations and editing them manually is an highly time-consuming task. So, I would like to know if there is a way to automatically correct Delauney violations and if so, how it is done.

And after the Delauney violation corrections, how to automatically perform the equilateralization of the triangles?

There is an automatic mesh smoothing option in FEFLOW that may help to lower the number of Delauney criterion violations. When generating the mesh, Triangle has an option to produce Delauney-complient mehes. However, triangles violating the criterion may point towards a non-ideal mesh geometry, but they will not inhibit FEFLOW from running well. So I would typically not do a manual correction.
