| Summary | 0004216: Wrong edgeGrading when using BSpline | ||||
| Description | I am trying to use the BSpline edge to create a block around an aerofoil. My test case is presented in the attached file. I am using as well an edgeGrading so each edge can have its own grading. When I run blockMesh, the cell distribution is wrong. I can observe, from the aerofoil towards the outer circle, an increasing ratio until a certain point, where the growing is stopped and it restarts again. I attach as well two images to illustrate my situation. The gradings to take care are: - grading_Y_le_extra - grading_Y_le_intra - grading_Y_te_extra - grading_Y_te_intra | ||||
| Steps To Reproduce | Unzip the test case Run blockMesh Visualize in paraFoam | ||||
| Additional Information | - Even with a grading of 1 this error persists. - I found the problem in both spline and BSpline methods. - I have no problems with the grading if both vertices are connected through a line. | ||||

The problem I have found is that, for this configuration, the "segment" variable was increased and the control points were different. |

This is a known issue and has been bugging me for a long while. It occurred to me today that an algorithm I came up with a while ago for distributing values evenly across distributions and in patchCutLayerAverage could also be used to correctly distribute the points along a spline. I tried it and it works. So, fixed here: https://github.com/OpenFOAM/OpenFOAM-dev/commit/bedceca2104284ce1e92ba427ec2dc144bab1d5d |
