Description
It can be interesting to create objects inside a meshed geometry whose CAO discretization is not available.
In order to do so, we rely on the MMG functionalities described in http://www.mmgtools.org/mmg-remesher-try-mmg/mmg-remesher-tutorials/mmg-remesher-mmg2d/implicit-domain-meshing, which create an interface from the 0-level set of a function.
The corresponding example can be found in the MMG repository in /libexamples/mmg2d/IsosurfDiscretization_lsOnly/main.c.
It is necessary to:
- provide a .mesh file, containing the mesh where the function is defined
- provide a .sol file, containing the function defining the interface
The steps are
- create functions that write the .mesh and .sol files
- create a circle on a square mesh using the function
(x-x0)^2 + (y-y0)^2-R^2 - create the level set associated to a generic body and place it in the meshed geometry (translation, rotation, scaling of the body coordinates & extension of the level set onto the meshed geometry)
- add c++ API
- add python API
- add mesh generation tool
