hello guys, I am new to CFD community and I would need your experience for something (maybe) too trivial, but because of my level please forgive me.
I have a mesh file, whom I am trying to import into OpenFOAM 1.6 I followed (maybe not 100% sure) http://openfoamwiki.net/index.php/Fluent3DMeshToFoam in order to have the respective mesh file. Now I would like to set some boundary conditions and run the icoFOAM solver. I know that I can do it by hand, but I am wondering whether there is any "easier" way to set it without editing files since it is extremely error-prone. [I am thinking like Fluent-way, create mesh, set boundary, run simulation. it is the same here. right? - or what else would I need in order to have a parallel simulation starting from the previous mesh file] Thanx all in advance T3rmy |

If you want, you can write a script in whatever language you prefer (bash, m4, ...) to generate your blockMeshDict, and your initial conditions files once for all, if you plan to do a parametric study or a grid refinement study. How to run cases in parallel is explained in the damBreak tutorial in the user's guide. Best, Alberto

I have been experimenting with another 3rd party program called "Engrid". This will import an ascii "*.msh" file, and allow the user to pick the boundary conditions and then directly write to the OpenFOAM file structure.

Yes. I agree. I like having a deeper understanding of how the code is processed and what is actually occurring.

I would like to thank sincerely all of you for your answers. The main reason that I would like to have this kind of software is to compare the "handwritting" with the "derived" version and check if I had done everything correctly. Of course I agree up to the point that editing gives insight and knowledge but at the starting point, where I am, personally I believe is the best way out.
Once again thanx all and waiting more proposals (if any) T3rmy |
