We simulate the turbulent flow around a cylinder at Reynolds number = 3900 using the VMS-LES formulation. The channel domain is discretized using linear hexahedral finite elements, and the cylinder is represented by immersed surface. The no-slip condition is weakly imposed on the non-conforming boundary via the VMIB (Variational Multiscale Immersed Boundary) method. The Dirichlet boundary condition is accurately imposed even when the computational grid is not aligned with the object boundary.
