AddLayers on an Airfoil
2 Attachment(s)
Hi Foamers!
I have a problem in creating the Boundary Layer on an airfoil geometry with SHM. The castellated and snappy phase are ok whereas "addLayers " results in no layer added. Could someone help me? Thanks a lot Roberto I attach the snappyHexMeshDict and the log file for the addLayer phase |
Have you tried this (from your log):

Hi!
thx for your answer. Yes I did it but no layer is added... I also changed the exp ratio to 0.1 to have a greater avg thickness. Roberto |
I would suggest you to stick with the default parameters and then change only one of them at a time. Every time remember to get rid of every file mesh related.
For example, you set Quote:
/------------------------------------------ Layer 3 | c | /------------------------------------------ Layer 2 | b /------------------------------------------ Layer 1 |_a_______________________________ /////////////////////////////////////////// Wall expansionRatio = c/b = b/a The layers should grow in height when moving away from the wall. In your case they are getting smaller. Also Quote:

Do you need snappyHexMesh? If feasible for your airfoil you could use my little airfoil mesher, found here: http://hvirvel.dk/airfoilmesher/

Hi,
i have a question to the airfoil mesher. the linked website to worldofkrauss is not working to see the example dat-file. maybe you can show one? greetings Andy |
Greetings to all!
@Andy: Seems like the server for the worldofkrauss website is having bad luck. You can find some information here: http://www.rcgroups.com/forums/showt...3#post22118311 - it seems it was up again in July, but went down again now in August. Best regards, Bruno |
