MULTISCALE MODELS IN ACTION
Geometrical multiscale models have been subject of investigation by MOX researcher since many years.
Today, the focus is on multiscale problems characterized by the strong interaction between a tubular geometry and the surrounding bulk. This type of interaction characterize problems in various field ranging from the blood perfusion of biological tissues (left image) and the heat exchange in a nuclear assembly (right image).
The general idea is to model the narrow geometries as monodimensional inclusions in a three dimensional domain. The particular coupling operator we use does not require the conformity between the mono end the three dimensional meshes resulting in a general low computational cost of the associated problems.
