The contact angle on the nozzle walls is 70 degrees, and on the substrate is 20 degrees. I coarsened the mesh away from the substrate as I was getting the floating point error, and I mostly need resolution to solve for the wet film boundary and profile. What I have not tried yet (I am still running another iteration of the model) is make the mesh finer just below the nozzle exit, between the lips and the subsrate. Would you suggest I follow this avenue, and if it does not work, what would be the next steps?
Thank you for your time, Rob.
