**v2.04.402** SDLV402 - Dynamic substructuring: incompatible mesh and mode
=====================================================================================

**Summary:**

The objective of this test case is to calculate the natural frequencies of two coupled tiles. With this in mind, mesh incompatibility functionalities in dynamic substructuring are tested, as well as coupling by interface mode.

The test case is composed of a :math:`\mathrm{3D}` model, of each of the tiles.
