Can preCICE be used for volume coupling?

We are actively working on a new linear cell interpolation mapping.

For 2D cases, you will be able to define a triangular mesh and configure preCICE to interpolate inside the cells

For 3D cases, we plan to add support for tetrahedral elements to both the API and the above mapping.

Short update: The linear cell interpolation mapping was released with preCICE version 2.5.0.
