wigley hull tutorial-no snapped faces
2 Attachment(s)
:) Hi to everybody,
i'm a rookie with openfoam at very first attempt... i've some problem with snappy mesher: i've followed this tutorial:http://www.hydroniumion.de/general/s...mesh-tutorial/ andi've reached after various loop of debugging the latter steps... the only problem is that snappyhexmesh doesn't snap the face on the grid... so there's few difference between mesh at time 1 and mesh and time 2. i've attached a screenshot to clarify the problem.. i've turned off all of meshQualityControls Any idea? Thanks |
Hi Allessandro
hard to tell as the link that you posted doesn't seem to work and i couldn't find the corresponding thread in the forum. As for your SHMDict: that looks good and should actually work. But here's a guess: In you SHMDict you put Code:
maxGlobalCells 2000000; Have a close look at the output of snappyHexMesh whether or not it tells you that the "overall cell limit ist reached" Otherwise attach the output of snappyHexMesh so we can have a look You can do that by redirecting the output with ">" to a file, e.g. Code:
snappyHexMesh > snappy.log Code:
snappyHexMesh | tee snappy.log |

Hi Allessandro,
i tried your SHMDict with the wigley-hull-tutorial and it works just fine. I even changed blockMesh to only half the domain as shown in your screenshot. As the mesh is little too large i had to change the following line to keep the cells under 2Mio. I left everything else unchanged. Code:
refinementRegions { hull { mode distance; levels ((0.1 3) (0.4 2) (1 1)); } } The only difference I found is the version: You are using OpenFOAM 2.0.1 ... where I'm using 2.1.0 ... So if you can try to change to OpenFoam 2.1.0. Hope it's that simple! |
