Hi Foamers,
I have a question about symmetry in OF. Let's imagine a case with two identical air jets blowing along one axis and in opposite direction. ---> <--- There is a symmetry plane on this little drawing. Can I only mesh the left half of it and use an empty BC for the symmetry plane? Or maybe if I do so the simulation won't suceed? My geometry is more complex and I'd like to simplify it but I have air jets blowing in every directions... Thanks for helping. |

Ok thanks!
If I have this drawing (with --> being an air jet) <-- --> <-- --> <-- --> <-- --> <-- --> Let's say I only represent: <-- --> with two symmetry planes, one on each side. Should I have two groups : leftSide and rightSide, each group with the BC "symmetryPlane" or can I have only one group with the two sides in it and one BC? Thanks!
