I'm doing a case where i have a wall being heated and i need to make a flux between that wall and a air(which surround the wall).Please help me

You are not giving enough information for anybody to answer your question. What solver are you using? Maybe include an image. Give a bit more detail about your model setup and you will get answers. I've seen heatflux setup in the T file under the 0 directory for buoyantBoussinesqSimpleFoam (http://www.cfd-online.com/Forums/ope...mperature.html).

Dear Grimoli


1- dont post similar question several places in OpenFOAM, instead of be much more patient to get answer

2- you can read this post to find how to ask a question

3- between two regions there are special BC's which for example assure energy balance

4- why dont you add fixedGradient to your solidWall? (sorry i could not see your picture , the given site is filter where i am , so i can not help any more )
