 April 18, 2005, 10:22 creating mesh using Gambit #1 Rucy Hong Guest   Posts: n/a Dear all, Could you tell me how to define different blocks using Gabmit? While using Gambit, we can create different 3D objects. If we combine those objects together, we can not name those original objects as fluid1, fluid2 or solid? One solution might be: to create 3D objects and generate meshes for those objects, and combine them together using TGrid? Is there any better solution? Thank you very much in advance. Rucy

If instead of uniting the volumes, you connect the faces where the two volumes touch, then they remain as separate volumes (and they share the face you connected so that the mesh is continuous through the domain) and you can define them as different continuums where you define the rest of your boundary conditions in Gambit. Hope this helps, and goodluck, Jason

I'm modeling a drop of liquid that undergoes mass diffusion while situated within a large volume of (a different) liquid. At first the surrounding volume of liquid is stationary (or 1e-10 velocity), but then later it will flow in the x-direction as the drop of liquid maintains its original position. Will Jason's suggestion of keeping separate volumes with faces connected work for my scenario? I originally made the drop a wall, but I don't think that allows diffusion into the surrounding continuum. Also had difficulty defining the interior of the drop as "internal, fluid" since the face of the drop was already associated (subtracted from) the surrounding volume...
