Well, I was just thinking about the various places we use the inverse map... If they are affine the newton iteration would be fast, but setting up the map would be be (some unquantified amount) more expensive than in the lagrange case.
Not to mention how much memory we'd be wasting to hold the higher-order (0 valued) coefficients for the affine elements in the volume. -Ben ----- Original Message ----- From: Roy Stogner <[EMAIL PROTECTED]> To: Kirk, Benjamin (JSC-EG) Cc: [email protected] <[email protected]> Sent: Tue Nov 11 09:09:05 2008 Subject: Re: [Libmesh-users] Subdivision surface based FEM On Tue, 11 Nov 2008, Benjamin Kirk wrote: > To keep the code anything resembling efficient, we'd need to make sure > multiple mapping types are supported at the same time...

I think as long as the majority of our elements are interior with affine maps we're fine. --- Roy ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
