[FAQ]

When trying to create a new tri mesh on a surface, reusing parts of an existing quad mesh, we might experience some difficulties getting a smooth size transition between the 2 zones. The usual methodology for enforcing a proper size transition is to remesh the “tri” zone with a “meshed” size function using an appropriate growth rate (e.g: 1.2, which is the default value), based on the adjacent zone The tricky part is that, in this case, the adjacent part contains quads, and therefore cannot be used as a reference zone for the size function. In order to work around this, take the feature edge surrounding the “quad” zone as the remeshing reference for the size function. This will lead to the desired smoothness in the mesh transition (see attached pictures for example)
