Hi, boys and girls,

With VOF method, A UDS was adopted to simulate the distribution of a material under water and air twophases flow.

The concentration of the material in A area will vary with time.The concentration of the material in B area will not vary and be a constant. And the interface between A area and B area will vary, but can be traced by air or water volume ratio.

my question is how to write the code to set the concentration of the material in B area as the constant at every timestep.Please see the attachment.

Thanks a lot!
