Micro Abstract:
In the presented work the Deforming Spatial Domain/Stabilized Space-Time method extended with NEFEM is coupled with a semi-discrete IGA solver. IGA exploits the geometric properties of NURBS for numerical analysis. However, parametrizing the 3D-domains typically needed for fluid dynamics is still challenging. Instead, NEFEM suggests the use of standard finite elements in the interior domain and special elements along the boundaries. A simplified data transfer and an error reduction is achieved.
