Witryna13 gru 2024 · I have looked at the FEniCS tutorials and documentation but I cannot find any mention to the possibility of implementing an immersed boundary method (IBM) for fluid dynamics. In particular, I want to develop a solver for the incompressible Navier-Stokes equations of internal flows with elastic walls. WitrynaImmersed boundary methods were first introduced by Peskin (1972) to simulate cardiac mechanics and associated blood flow. One distinguishing feature of this …
Witryna13 lut 2024 · The flow solver utilizes a sharp interface immersed boundary method, and in the present work, we extend it to account for the thermal buoyancy using Boussinesq approximation and couple it with a spring-mass system of the VIV. The one-way coupling utilizes an explicit time integration scheme and is computationally efficient. Witryna25 sty 2024 · The immersed boundary (IB) method is an alternative technique for handling complex and moving boundaries in mesh-based methods. It utilizes non-boundary-conforming meshes in numerical discretization, and the no-slip condition on the surface of the immersed object is enforced by adding a volume force to the …

The pressure and the boundary force are treated as Lagrange multipliers to enforce the incompressibility and no-slip wall constraints.
Witryna22 kwi 2024 · State: This is just a collection of pre-allocated arrays to store the vorticity, streamfunction, velocity flux, and body forces (including lift and drag). It also has storage for the "memory" of the multi-step scheme for the nonlinear terms. Once a Problem and State are defined, the basic time-stepping is to just call advance! (state, prob, t).
