Compute Three-Phase Contact Line
To describe the interface between different materials, the length the of three-phase contact line at which three different materials meet can provide helpful information. To compute a three-phase contact line, at least 3 meshes need to be loaded. For the above brick example, we can choose the three meshes and start the computation.

The length of the contact line and the number of edges is given.

The data can be validated easily for this small structure, which has a width of 20 voxels and a voxel length of 1µm.

The surface mesh is shown below. As it is shown in the result viewer, we can count 21 edges, where the first and last edges of the observed contact line are half as long as the other 19 edges.
