Witryna19 lip 2024 · 2 Immersed isogeometric analysis. With the aim of introducing immersed methods, the used notation, and the main ideas behind this work, let us first introduce a classical Poisson’s problem as our driving example. Even if the problem is presented in a 3D context, the same ideas are directly applicable to 2D problems.

WitrynaIsogeometric analysis employs complex NURBS geometry (the basis of most CAD packages) in the FEA application directly. This allows models to be designed, tested and adjusted in one go, using a common data set. [1] The pioneers of this technique are Tom Hughesand his group at The University of Texas at Austin. Witryna19 lip 2024 · A Skeleton-stabilized ImmersoGeometric Analysis technique is proposed for incompressible viscous flow problems with moderate Reynolds number. The proposed formulation fits within the framework of...
