WebLarge Eddy Simulation (LES) Large Eddy Simulation ( LES) is one of the most promising methods for computing industry-relevant turbulent flows. It is used to predict unsteady flow behaviors with lower computational cost as compared to Direct Numerical Simulation (DNS). The essential idea of LES dates back to Joseph Smagorinsky (1963) in ... WebReconstruction of cells information when given mesh in polyMesh format [duplicate] The polyMesh format used in OpenFOAM is an intelligent format for which 'cells' file, i.e. the file giving list of nodes that make a cell, is not needed. The way to reconstruct geometry data such as ... fluid-dynamics. finite-volume.
