Sharc’s Extreme Mesher, has just been released with improved meshing algorithms.

Months of work behind the scenes has resulted in new optimisation algorithms for CFD solvers which may have had convergence problems in the past. The enhanced routines are included in the default settings of Harpoon v 2.5 which also includes an option for ‘super converge’ to help with any particularly difficult geometries.

The figures below show the same complex model meshed in v2.4 and v2.5 of Harpoon. Exactly the same settings were used for the meshing and the solver.

The optimisation is not necessary for all solvers or all cases. It is very much case and solver specific. The algorithms have been carefully developed to help solver technologies that struggle with convergence on complex geometry.

Other improvements include:

* Surface recovery

* Matched meshing

* Hole finding/fixing

* Surface cleaning

About Sharc

Founded in 1997, Manchester based Sharc is a developer of pre-processor software for finite element analysis (FEA) and computational fluid dynamics (CFD). Its flagship Harpoon mesher produces high quality body-fitted hex meshes. The automatic generation of hex dominant volume meshes and/or quad dominant surface meshes bypasses the need for time consuming surface mesh generation and grid density specification.
