For example, after a cube is divided into a three-dimensional mesh (in fact, one-dimensional and two-dimensional meshing will be called first), the one-dimensional line element will be stored in the object of the edge where the element is located, and the two-dimensional element will be stored in the area object where the element is located. Gmsh is built around four modules: geometry, mesh, solver and post-processing. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities.

If the subsequent operations involve the grid data structure, you need to understand that the Gmsh grid is stored in the corresponding entities. Gmsh is an open source 3D finite element mesh generator with a built-in CAD engine and post-processor. Generally directly under the first-level namespace, functions related to geometry are often in modelUnder the namespace, functions related to meshing are usually in meshUnder the namespace. Global functions, such as open、merge、writeEtc. You can basically understand the commonly used functions by viewing the official sample files. The way to use Gmsh API is relatively simple. # include # include int main ( int argc, char * *argv ) to sum up External solvers can be interfaced with Gmsh through Unix or TCP/IP sockets, which permits to launch external computations and to collect and process the results directly from within Gmsh’s post-processing module. In this first extended tutorial, we start by using the API to access basic // geometrical and mesh data. These // additional features are introduced gradually in the extended tutorials, // starting with `x1.cpp'. - // // Gmsh C++ extended tutorial 1 // // Geometry and mesh data // // - // The C++ API allows to do much more than what can be done in. Need to add -lgmsh option when compiling to include dynamic link library.

The code is slightly modified on the basis of x1.cpp of the official tutorial, and Chinese comments are added to some parts that require attention. The following takes the C++ version as an example. When using the Gmsh API, you only need to import the corresponding library.

Add cmake -DENABLE_BUILD_DYNAMIC=1… option when compiling.

Download the SDK from the official website.Mesh -> Define -> Size Fields -> New -> Boundary Layer (with the GUI). Now, I want ton add some prisms layers at walls to take into account the boundary layer. The binary lives inside gmsh-4.5.6-Linu圆4-sdk/bin. The SDK has C++, Python, C and Julia bindings and also the standalone Gmsh binary. I have no problems to generate 3D meshes which are well exported to OpenFoam. The quickest way to get Gmsh is using the SDK. The grid generator and solver are connected to form an overall framework. STP file and I tried to use the GUI to generate meshes. Today, I will introduce the third way to use Gmsh: use Gmsh API to integrate it into other software. In the first two articles 1、 2We introduced the graphical interface and the use of the built-in parser geo script respectively.
