Use the right-hand side of the dialog to define material ID and constituent material for each of the STL meshes, the pore space, and the overlap.

Number of Meshes

The number of meshes present in the selected files is automatically entered. Typically, the number of meshes corresponds to the number of chosen files, but OBJ files might contain multiple meshes.

Table of Meshes and Materials

The table is automatically filled when Suggest inputs the parameters into the dialog. The first column contains the name of the mesh file. It may include the name of the mesh plus a number if a file contains several meshes.

A material can be assigned to the listed mesh by clicking its button in the second column.

For example, the material of the Casing can be set to Aluminum, and the material of the Pleat to a porous material filled with air.

Pore Material

Below the table, set the background material. The background material always has the ID 00.

Define Default Overlap

Meshes might overlap if several files for meshes are imported, so that some voxels possibly belong to several materials.

Use this option to assign a specific material to overlap regions. If no default overlap is defined by the user, the material ID of the overlapping regions is automatically computed through a binary addition of the IDs of the overlapping materials.
