splitting boundary patch into several patches
Hi everybody,
is there a posibility after running snappyhexmesh etc. a boundary patch in for example 6 pieces along one direction? the problem is the following: i splitted a blade in 6 different stl files. the geometry is allways the same but at the region where 2 parts are connected the layer mesh looks very bad. so i want to mesh it as a single patch and splitt it afterwarts into several patches. so that i can extract forces along the blade. is there a possibility? best wishes Andy |
nobody an idea?

Have you seen the new feature in version 2.2 that allows you to do approximately what you want, i.e. write forces in "bins" along a specific direction?
See the release notes: http://www.openfoam.org/version2.2.0...processing.php |

i have to work with OpenFOAM 1.6 extend. Do you know if i can calculate the Forces after finisching the computation? |
In the case of using 1.6-ext I have no ideas (other than splitting the boundary patch as you suggested). Sorry.
(Perhaps you can take this piece of code back into 1.6-ext? I guess this part is pretty similar). |
Hi AW!
Since you have those individual STL's, you could use them to create a faceSet( use topoSet). This faceSet can then be used to create patches using createPatch and you could call your force functions to calculate on these patches. This might work. Cheers! Akshay |
Or...
You could use 'sample' utility. This works on STLs. But i doubt if the extend version has the 'SampledtriSurfaceMesh' type. But I believe you could setup the 2.1 'sample' code in your environment. Cheers Akshay |
