| Summary | 0003754: Rudundent expression in blockMesh causes performance lost | ||||
| Description | There's redundent expression in "/applications/utilities/mesh/generation/blockMesh/blockMesh.C". It leads a recomputation for blockMesh's cells, which could be avoid. https://github.com/OpenFOAM/OpenFOAM-dev/blob/master/applications/utilities/mesh/generation/blockMesh/blockMesh.C - line276 const List<FixedList<label, 8>> blockCells = b.cells(); - line305 celli += b.cells().size(); The b.cells() in line 305 is same as that in line 276. It can be fixed by the statements below. - line276 const List<FixedList<label, 8>> blockCells = b.cells(); - line305 celli += blockCells.size(); | ||||
| Steps To Reproduce | Just look up the source code, then can easily find out. https://github.com/OpenFOAM/OpenFOAM-dev/blob/master/applications/utilities/mesh/generation/blockMesh/blockMesh.C | ||||
