Research on Data Structure and API of All-hexahedral FEM

Based on the characters of all hexahedral finite element meshes, the primary requirements for their data structure are put forward. The whole logical relationships and references of mesh entities are analyzed in details so that their clear charts are formed. A consistent application programming interface in the form of DLL is provided using C++ language, so multi programmer can utilize the mesh database. The example verifies that the algorithm with the above mentioned data structure and API gets twice the result with half the effort.
