Hi Guido, Sorry if my message wasn't clear - I am using projection. However I am using quadratic elements, and I think that some inbuilt interpolation in this function is producing the funny values. I hope that makes sense? I can send a picture if it makes it clearer?
Thanks, Katie ________________________________________ From: Guido Kanschat [[email protected]] Sent: 17 August 2011 11:54 To: Katie Leonard Cc: [email protected] Subject: Re: [deal.II] Projecting Initial Values without interpolation Katie, you might want to do projection instead of interpolation. The results might look even funnier, but they should be more accurate.

Currently the Vectortools::project function (as used to set initial values in steps-21, 23, 31) produces some funny values as the point of the step function, and I think this must be to do with interpolation. I'm using continuous Galerkin methods. Any help/ideas would be very gratefully received!
