Description

<p>In this paper, we describe a practical fluid volume-mesh generation techniques for the Isogeometric Analysis (IGA). The space–time slip-interface (ST-SI) method can be applicable NURBS descritization in space and time, however a good mesh generation for fluid is not trivial. In this paper we use the existing techniques for mutli-block structured mesh technique and projection techniques to generate fluid volume mesh. The ST-SI method allows having C−1 descritization without loosing accuracy. This diminisies the knot restriction between NURBS patches. The paper includes examples and how to control the mesh resolution and qualities, and test computations with the ST method.</p>
