method of manufactured solutions for unsteady problem
Hi all,
Is anyone familiar with the method of manufactured solutions? I using the method to evaluate my unsteady code. I needed to know if the code needs to be run for a long time.

Not sure I'm getting your question. You chose a time-dependent function as a source, plug in it, evaluate the L2 norms at some time and then do the grid refinement...

mail me your email, I will send you a paper and a note about how to do that in 3D. I recently was testing starccm against it. So have that paper i used.

or just google "sandia labs report manufactured solution", they have done some extensive testing with this method. You will find it done regularly in journal papers about new discretization methods, and it is pretty easy to do.
no witchcraft! :)
Good luck!
