Bob’s Research Corner: Grid Deformation – Part I

Welcome to Bob’s Research Corner!  In the past, we did not have a convenient way to provide research news to you – unless you considered spamming your email occasionally a good way :).  When I redesigned the website, I made it very easy to post quick news updates.  You can thank Bill for the idea (or maybe blame him — your choice!)  I plan to provide updates on my research once or twice a quarter.  It’s up to you if you want to read my ramblings…..

With the release of v7.0, I’ve been able to shift my focus from Overset to a new project.  I had several ideas/interests and decided to look into Grid Deformation.  Cobalt has been able to calculate solutions on deforming grids since the release of v6.0 (February 2013).  Our plan was always to interface with a 3rd party grid deformer.  Unfortunately, that has not happened yet.  So I decided it was time to see if I could develop our own grid deformation tool…

I’ve spent the last month looking at grid deformation methods, writing little research codes to test out ideas, etc.  I’m finally ready to provide a little preview.  It’s only 2-D with rigid boundaries — but the interior of the grid must deform. Every step has a valid Cobalt grid…I’m ok with +/-90 degree rotation! If you have any questions, leave a comment or send me an email. Check back in a few weeks when I hope to have more to show you.
