This is a GUI version of Im2mesh (https://www.mathworks.com/matlabcentral/fileexchange/71772-im2mesh-2d-image-to-finite-element-mesh).
A detailed tutorial is available in the zip file.
News
  • Version 2.20 supports Gmsh.
  • Version 2.16 updates the DOI. Im2mesh is now citable!
  • Version 2.10 supports quadratic elements.
Features
  • Exactly preserve the contact detail between different phases.
  • Incorporates polyline smoothing and simplification
  • Able to avoid sharp corners when simplifying polyline.
  • Support phase selection before meshing.
  • 3 mesh generators are available for selection: MESH2D, generateMesh, and Gmsh.
  • Generated mesh can be exported as mat file (MATLAB), xls file (Excel), inp file (Abaqus), and bdf file (Nastran bulk data, compatible with COMSOL). The mesh can also export as other fomat files via Gmsh, such as STL.
Installation
  • Im2mesh_GUI can be installed in two ways: MATLAB app or standalone desktop application.
  • For using as MATLAB app, you need to install MATLAB software, Image Processing Toolbox, and Mapping Toolbox. When MATLAB software is opened, you can install Im2mesh_GUI by running "Im2mesh_GUI.mlappinstall" in the zip file.
  • For standalone desktop application, you don’t need to install MATLAB software or any MATLAB toolbox. Please send me an brief email to get the Installer - "Installer_Im2mesh_GUI.exe".
