Hi everyone,
I'm a new starter of this software and puzzled by the way of writing the governing equation (in CFD) in PDE form. The information provided in the mannul seems not to be suifficient enough. Is there any recommendation of reading material regarding of this problem?
Thanks a lot!!

Also not sure how to transform the Navier-Stokes equations into the PDE general form as used in the example of the back step flow.
Anyone can help?

Hi

for the reading check

www.comsol.com/academic/books/

I recommend this one to start with, specially for PDE basic approach, even if it is not relly fluidics first up

www.comsol.com/academic/books/mmwfem/

There are a couple of other titles on fluidics but I do not know them

Have fun Comsoling

Hi Chang

Here it is what you need:
www.comsol.dk/community/forums/general/thread/1874/

By the way what is your final goal in developing PDEs for NS?Are you going to extend it to include other physics as well?

Regards
Naveed

Thanks, Naveed.

Currently i'm trying to use the PDE general form to solve the 2-D cylinder flow with confined walls and will extend it to 3-D once the first part done.
