The Interface Analyzer package is a MATLAB-based tool designed to analyze and visualize 3D interfaces from rgrid data of Polymer Self-Consistent Field Theory (PSCF). This package provides functions to process the data, generate isosurfaces, and save the results for further analysis or visualization.

Use the analyzeInterface function to process rgrid data in example:
[meanCurvature, stdCurvature, interfaceArea] = analyzeInterface('SG.rgrid', 'imds_face', 'imds_coord', 'imds_curv', 'imds_gauss')
SG.rgrid: A field representing monomer density across a regular grid, calculated using Polymer Self-Consistent Field (PSCF) theory.
imds_face: Connectivity data for a triangulated mesh, showing how vertices are grouped to form triangles.
imds_coord: The coordinates of the vertices in the triangulated mesh.
imds_curv: Mean curvature values calculated at each vertex of the mesh.
imds_gauss: Gaussian curvature values calculated at each vertex of the mesh.
The development of the Interface Analyzer package was guided by valuable insights and methodologies derived from various works:
