@SaverioIV but how does it conform. are the cells always squares of increasingly small size to approximate the form or are special non square cells used on the boundary?

I am wondering, how do you implement the geometry in the matrix model of the fluid? chopped cells? or is it either or, always complete cells

@DanFrederiksen The Navier-Stokes equations are solved (with a bug in this example!) on a time-dependent, body conforming grid. You can take a look at my website if you want and download the shape-changing paper on the research page. Best, S.

@DanFrederiksen The fluid is discretized on a time-dependent grid which maps conformally along with the changing elliptic shape. See: maeresearch.ucsd.edu/spagnolie/SpagnolieShelleyPoF09.pdf , which is one of a few products of this code *after* the bugs were worked out...!

Which way was the flow direction intended to be?

This is a "simulation" :) of a shape-changing body in an initially quiescent flow. The red and blue are supposed to be the fluid vorticity, which should have stayed close to the body, and should have been left-right symmetric. This result *wasn't even close* to correct when I ran this buggy code. But it made for a good laugh.
