attach detach in parallel
Hi Foamers,
who of you has successfully applied attach/detach topo changes in parallel? How to decompose the grid. I ve been told that the faces have to be treated on one processor and shouldn t be distributed on several processors. Thanks in advance! Cheers Peter |

Hi Foamers,
who of you has successfully applied attach/detach topo changes in parallel? How to decompose the grid. I ve been told that the faces have to be treated on one processor and shouldn t be distributed on several processors. Here, a small description of my problem. I am using OF-1.6-ext for in-cylinder aerodynamic problems. For the valve and piston motion I am using the accordionEngineMesh class. It uses the FEM automesh motion solver for the valve and piston motion and for valve opening and closure the attach/detach boundaries. And here the problem pops up. Everything works fine in serial but in parallel it doesn t. The problem comes from the attach/detach faces. When I decompose my case on 2 processors and I try to run it following error message appear. Quote:

Did you made any progress on the topic that you have described here? I would like to simulate real engines in OF, so this topic is essential for me. It will be so great if would you mind if you share your insight to the problem ;) |
Hi, Peter,
I'm recently working on a project and I have troubles on setting up the dynamic mesh feature. I've looked up for information but haven't figured it out. It seems that your problem has a similar feature with mine. Could you share me your simulation setup as a tutorial? Thank you. Joe |
