DOC/DPF Geometry
 
Hello! :)
I'm so glad to participate with you, and exchange information!
well! I've a problem with ICEM to draw the geometry of DOC/DPF or one at the least! the cellules and their materials (washcoat) are my big problem to draw!! I have all the parameters to draw the geometry! I made an example with one cellule but I didn't add many parametres because I don't know how to declare it! like the materials and the exhaust gaz! (sometimes CFX-pre don't run and notice me error generally)
so please would you help me to realise this geometry and its mesh with ideas or even some tutorials which can help me!! (I took a look about the tutorials in the help)!
thank you before! and accept my regards all!

N.B: DOC = Diesel Oxidation Catalyst
DPF = Diesel Particulate Filters
they use them in the control of emissions in the diesel engine (exaust systems)
