Seeder Mesh Generator
The goal of Seeder is simple: create an octree mesh out of a given geometry. Typically the given geometry is given in the form of STL-files. As simple as this goal is the basic idea for the construction of this mesh. The user has to define at least the basic mesh information to generate the most simplest mesh, fully periodic cube without any geometries. Basic mesh information are bounding cube, minlevel and folder. Bounding cube is the root node of the octree, defining the complete universe, from which all element are derived by recursive bisection, global minlevel is the minimum refinement in the fluid domain and folder is the location to dump the mesh output in treelm format.
The user can also define a set of geometries, that should describe certain aspects in the mesh. Most importantly the boundaries of the computational domain. Those have to consist of some supported geometric primitives, right now the following primitives are available:
Additionally some combining objects like Planes and STL-files can be used. They are automatically translated to these primitives.
Transformations like translation, scaling, reflection and rotation can be applied to all geometric primitives.
Finally, those geometric definitions, have to be given one of the attributes. Attributes are defined by their kind:
a level, that describes the minimal refinement level by which the object should be resolved and some kind specific further values, like a label for the boundary conditions.
For further details see the FORD generated documentation.
