…ification The mesh is named StaticMesh* because it does not change when being used. 1. The code was copied from SOLVCON (https://github.com/solvcon/solvcon). 2. Add basic shape tests for the mesh object. 3. Add CellType but it is not used nor tested at all.
Add mesh.hpp to house code of unstructured mesh
… object This is the first step: Create a simple test function for the object creation.
Note that the cell type ID is augmented by 1 (the valid type ID started from 0 in SOLVCON, but now it starts from 1 in modmesh). Use of 1-based index leaves 0 to be the invalid sentinel for the type ID in modmesh. Use the trivial triangle unit tests for build_faces_from_cells().
Ref issue #34.
Ref issue #35.
Also include porting count_ghost() and fill_ghost(). Ref issue #36. Copy code from SOLVCON: https://github.com/solvcon/solvcon/blob/8dd74fa848b8d14d7796138ce199d0ae2e70235f/libmarch/include/march/mesh/UnstructuredBlock/class.hpp#L312.
Add code to build the data for 2D unstructured mesh object
Use std::algorithm to count maximal number of faces for interior data.
* Add SimpleArray::vptr() API to return the pointer to an element. * Change the use of some local pointers with SimpleArray API.
Remove use of pointers to shorten the code.
Add helper class detail::FaceBuilder to house the face building code. The helper functions include: * populate() * make_ndfcs() * make_dedupmap() * remap_face()
I wrongly coded it to be swap(SimpleArray && other). Change it to swap(SimpleArray & other). Also use noexcept for C++17.
…ension by reconstruction
Make the function a little bit flatter.
Ubuntu g++ 10 detected these missing includes.
Make inclusion more complete
