What should I do to impose a heat flux on a heat transfer case on OpenFoam??
Should I put it on the wall ''changeDictionaryDict" configurations??I tried to search it on OpenFoam tutorial but I had no sucess at all.Can someone help me please??

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 :D, the given site is filter where i am ;), so i can not help any more )
