The Honeycomb (TWC) app generates a three-way catalyst monolith with hexagonal combs.

Clicking Edit opens the Honeycomb (TWC) Parameters dialog.

Define the following parameters:

• Result File Name,
• the Voxel Length,
• the Filter Length in Z-direction without inflow and outflow region,
• the Number of Unit Cells in X- and Y-direction,
• the Wall Thickness,
• the Inflow Length, defining an inflow region,
• the Outflow Length, defining the outflow region,
• the Channel Side Length, for the hexahedron sides,
• and the Unit Cell X Offset defining the cell positions in X-direction.

Clicking Run creates the honeycomb.
