Hello, Foamers!
I have a problem about the function "project" in blockMeshDict file. This blockMeshDict file is in a case about NACA0012(you can find it easily). The code is Code:
project ($aerofoil.xLower -0.1 $domain.zMin) (cylinder) // 0 (0.3 -0.1 -2) project ($aerofoil.xLead -0.1 $aerofoil.zLead) (aerofoil) // 4 (0 -0.1 0) project ($aerofoil.xTrail -0.1 $aerofoil.zTrail) (aerofoil)// 5 (1 -0.1 0) Is the function 'project' a mapping? What the relationship between the points "($aerofoil.xLower -0.1 $domain.zMin)" and cylinder(cylinder is a geometry)? How does the 'project' function work? I welcome any answer, and I believe the more discussed the question, the clearer it becomes. |

Hi,
I think "project" is projecting or mapping the vertex onto the surface indicated (cylinder or aerofoil), which has been loaded before. It should be referring to the source file you can find in the following link: https://www.openfoam.com/documentati...8H_source.html Other useful files are located in: FOAM_SRC/mesh/blockMesh Regards, Lorenzo |
