IIRC it's solving nondimensionalized Navier-Stokes equations, but with that caveat you're correct. > I ask this because I plan on adapting this example to solve > for velocities and temperature whereas the pressure difference > arises from a change in the temperature. Again any help is > appreciated. The pressure for incompressible Navier-Stokes is always going to be determined by (in conjunction with) the velocity. If you're doing temperature-driven nearly-incompressible flow, look up the Boussinesq approximation for how temperature affects buoyancy. --- Roy ------------------------------------------------------------------------------ _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
