OrthoMesh

OrthoMesh is an application for creating meshes for a range of structured orthogonal CFD codes, including FLACS, AutoReaGas, Fire Dynamics Simulator (FDS) and OrthoFlo. The tool accepts a reference geometry from GeomAuditry and exports it for use with the CFD code of choice.

Primary geometry

When exporting for use with a structured orthogonal code, the primary geometry is orthogonalised and aligned with the CFD mesh, according to the CfdMeshSpacing parameter specified by the user.

Secondary geometry

When exporting to FLACS and AutoReaGas, the orthogonal secondary geometry is exported directly as it is stored within the congestion database, and nonorthogonal geometry is discretised according to the CfdMeshSpacing parameter specified by the user.
