However I am in need of practical experience of yours regarding this problem type.<br /> <br /> many thanks Thu, 11 Mar 2010 17:10:35 +0000 3704.1268327435.9718 http://www.comsol.co.in/community/forums/general/thread/3704/#p9647 Hi,<br /> <br /> I have a cylinder in the flow using ALE method, coupled with mass transfer. It is very slow and usually I have a higher than inlet concentration in the flow domain, probably due to not enough mesh. I want to use a stabilization technique, but my concern is the moving boundaries. The artificial diffusion should not alter the flux into the cylinder boundary.<br /> <br /> Any recommendation?<br /> <br /> Many thanks in advance<br /> Wed, 10 Mar 2010 14:30:40 +0000 3704.1268231440.9647
