I had looked at DirichletBoundary class in the examples, but I had not realized that it works for all interpolation basis. What you describe is very impressive, and I will certaintly look deeper into the class. Thanks! Manav On Thu, Feb 21, 2013 at 4:17 PM, Roy Stogner wrote: > > On Thu, 21 F

Thanks, Roy. I have a preference for Lagrange interpolation for the structural (and some thermal) applications that I am working on, primarily due to easy application of Dirichlet boundary conditions. Perhaps hierarchic polynomials would also offer a similar feature (please correct if I am wron

Thanks David, this is helpful. I have a related question: L2_LAGRANGE provides the *discontinuous* interpolation using Lagrange polynomials, so I could use a quad4 and have as high as third order (currently, and I will be glad to contribute more). However, is there a way to achieve the same order

Hi, I am curious if the library allows for use of Lagrange elements in C0 discontinuous interpolation. Also, is it allowed to have an Lagrange interpolation of an order that is higher than the geometry order? For example, can I use a 4th order Lagrange interpolation on a quad4? This perhaps ma
