Mixture A+B and C+D

January 19, 2007, 01:37

I have two parallel adjacent channels. Mixture A+B flows in the upper channel and mixture C+D flows in the lower one. But I can't postulate these matetial in the program. I can't set-up the mixture both A+B and C+D, only one mixture appears in the boundary conditions pannel when setting the medium fluid.

How can it be possible?

Do you have created two Fluid domain in the mesh.( check if two fluids are there in the boundary conditions)

Do you have created two Fluid domain in the mesh. -->Yes. I do it in the specify contimuum types section.

check if two fluids are there in the boundary conditions -->Yes. Two fluids exist and I can determine each material for singel component in material name column. But if I choose species transport option to "ON", the material name colum disappears.
