WebThe principle behind blockMesh is to decompose the domain geometry into a set of 1 or more three dimensional, hexahedral blocks. Edges of the blocks can be straight lines, arcs or splines. The mesh is ostensibly specified as a number of cells in each direction of the block, sufficient information for blockMesh to generate the mesh data. WebWhile I am aware of many ways to circumvent this by external means like m4 or sed I'd …

Web9 de set. de 2024 · The Value Proposition of blockMesh. blockMesh, one of the meshing softwares packaged with all modern releases of OpenFOAM 1, falls on the extreme ‘user-control’ end of the aforementioned spectrum, to the point where a user could directly compute the positions of every node in the mesh in advance. WebWhile I am aware of many ways to circumvent this by external means like m4 or sed I'd like to make a point for changing it in a way to allow definitions of simple variables without the use of code compilation. Maybe by adding precompiled versions for simple tasks like multiplication of a veriable with a value or sin/cos operations. Tags: blockMesh
