Default Unsteady,viscous,incompressible methods

Is there anyone who has experience with solving unsteady, incompressible, viscous flow using their own code? I have written my own codes for steady flows, but have never done a time-dependent model and would like someone to confer with.

Hi there,

I am working with compressible, viscous, rotating, non-steady, two-dimensional flows; and I am writting all my codes. So I have some experience with time-dependent models, explicit and implicit with different restrictions on the time steps.

Do not hesitate to post here your questions and/or concerns and I'll do my best to help.

I did codes for unsteady viscous electrohydrodynamical flows in electrohydrodynamical pumps (by way, announcement of St-Peterburg, Russia EHD-6 conference you can find on www.univer.osmk/~rtf/POL.htm )

Also I did codes for unsteady transonic flows in cascades of turbomachines but for nonviscous and only for 2-D flows.

Hi Keith I use the SIPMLE algorithm for solving unsteady, incompressible, viscous flow (I study the oscillatory solutions in the problem of nature convection of cold water in a square cavity).

We have MANY YEARS of relevant experience! It is well-summarized in our new book, "INCOMPRESSIBLE FLOW AND THE FINITE ELEMENT METHOD", John Wiley & Sons, 1999(for the current hardcopy version); 2000(for the soon-to-be-released 2-part paperback version). One of our SPECIALTIES is just what you need: How to EFFICIENTLY march the eqns forward in time....AND, the methods that we describe are NOT limited to the finite element method....they apply to ALL numerical methods...
