Unsuccessful Intersection of Interfaces

You will likely get errors if you attempt to solve a simulation with few or no intersections in an interface. Therefore, when setting up simulations with interfaces, you should check the interface intersection as early as possible for problems such as:

Too few or zero intersections in an interface caused by specifying the axis of rotational periodics incorrectly.

A boundary may unexpectedly be left without any faces after the intersection process; therefore check the boundary icons.

The absence of any intersections in an interface usually results from the chosen boundaries not being geometrically adjacent to each other. For details on detecting and solving this, read about examining the intersection report.

In case there might be gaps or holes in the mesh, display the interface boundaries.
