 April 5, 2014, 16:25 how to implement these equations #1 New Member   Join Date: Mar 2014 Posts: 21 Rep Power: 4 Hi everybody I want to solve 2below equations that some how coupled to each other Do you have any idea how can I solve this problem without using "blockCoupledScalarTransport" dT/dt + d/dx(Uk) = 0 dk/dt + d/dx(UT) = 0 I want to use vectors or tensors, I was thinking to define a vector a(T ,k) and a'(k ,-T) and then solve da/dt + da'/dx = 0 do you know how can I implement this in openfoam? Thanks in advance, Sina
