Immersed Boundary Method: problems with .stl file

Dear all,
I am working on my master thesis project but it's been a few days that I am frighteningly stuck on a dead point. So I am asking here for help. I am trying to set up my own Immersed Boundary Method (IBM) problem starting from the tutorials that are present in the foam-extend4.1. In particular, I am referring to the movingCylinderInChannelIco one. Using the test case, everything works properly but the problems start when I replace the already prepared .stl file with one that I have generated myself, even though it is a very dumb one: a parallelepiped divided in only 12 triangles. Being more precise, the error that I receive, while executing the potentialFoam command, is the following: Quote:
In fact the tutorial gives few lines, in the directory "save/boundary", that need to be copy-pasted in order to include the .stl file into the previously generated blockMesh. I think that, building my own .stl file, I should modify the following lines but I am not able to figure how to do it. Quote:
For the sake of completeness, I remark the fact that I am working with the foam extend, therefore I cannot use the topoSet command. Is there anyone that know how to do it properly? Or how to get rid of this problem? I am available for further clarifications. Many thanks in advance. Enrin |

Hello YatengQ,
Yes, I solved it after a few tries. It turned out that you have to change the "startFace" parameter, according to your case. Hope it helps! |
