hi dear foamers
i want to simulate compartment fire caused by a fuel source which is at some height from the compartment floor. my main challenge is in generating mesh via blockMesh for this problem. by "cell correspondence" approach toward this case, if i assume the fuel source, a patch that fuel flows through it, what kind of patch should i use for the top face of the block located below the fuel source patch??

i repeatedly face the warning/Error that tells there are for example 9 undefined faces which the software categorize them as default faces of type empty
thanks in advance
