Improve boundary conformity - Githubissues

CHLNDDEV / OceanMesh2D

A two-dimensional triangular mesh generator with pre- and post-processing utilities written in pure MATLAB (no toolboxes required) designed specifically to build models that solve shallow-water equations or wave equations in a coastal environment (ADCIRC, FVCOM, WaveWatch3, SWAN, SCHISM, Telemac, etc.).

Improve boundary conformity #120

Open krober10nd opened 3 years ago

krober10nd commented 3 years ago

On termination, it's possible to repeatedly project only the boundary vertices back onto the 0-level set for better boundary conformity.
See here what I did in Python.

It removes some of the "dents" that happen when meshing with an implicit domain.

Here's the function call: https://github.com/krober10nd/SeismicMesh/blob/fa4cbc97a987d3468e6362fce6c76efe05f47bdf/SeismicMesh/generation/mesh_generator.py#L629

This is superseded by #264 which solves a 1D mesh generation problem prior to 2D meshing to gather pfix and egfix that conform in spacing with the mesh sizing function.
