Hi,

I am trying to simulate a fluid with a source and hence the divergence of the flow field is non-zero? However, whatever little experience I have had with comsol, it seems there is no way to introduce a source term in the equations. The divergence of velocity is always zero. Could you suggest how to incorporate non-zero divergence condition in the flow modules. Thanks.
