Nowaday many scientific libraries, applications are available on the internet. Especially application-level softwares are prepared by many organization, usually academic organization. There are OpenFOAM, MEEP, Elmer, FreeFEM and so on. Gmsh/GetDP is the one of the softwares.
Gmsh/GetDP is a Finite Element Method packages. Gmsh generates a mesh for FEM and prepare the GUI for the system. GetDP is a FEM engine to solve many partial differential equation sets. This is very powerful software but there are not many information on the software in Japanese. So we decided to prepare some lines to show how to use these softwares on this Three Wells' site.
