Hello!

I want to modify the reaction rate near the walls of a cylinder (2d problem). In order to do this, Ihave to "mark" the cells near the wall in order to alternate the reaction rate there. Can anybody tell me how the address these cells within an UDF because no sample is given in the manual.

Thanks in advance!

Peter
