Dear All, I recently updated deal ii, but I am unable to run the programs. The main problem appears as a set of warnings when starting to "make": ld: warning: directory not found for option

Yes I can confirm, I am using QProjector with a dummy face Quadrature right now it works as intended. Doug -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you

I just want to clarify that Dougs suggestion also works, if we use the QProjector class to lift the points on the face from R^(dim-1) to R^dim before we transform them: // Create a dummy quadrature from support points on face. const Quadrature dummy_face_quadrature(

Agreed. Sorry for the confusion. Looked back at my code and it's probably the most straightforward way. For some other unrelated reason I didn't want to use FEValues and directly deal with the Mapping class. Doug On Monday, June 22, 2020 at 5:05:57 PM UTC-4, Simon Sticko wrote: > > Hi, > >

Hi, Lex, given your previous question: https://groups.google.com/forum/#!topic/dealii/xghVE7Km78o If you are already using an FEFaceValues object with a dummy-quadrature (created from FiniteElement::get_unit_face_support_points()) then you can use one of the following functions on FEFaceValues

Hello Doug, Thanks for your help. However, I need to say, I just had done exactly what you described before I posted this question. "FiniteElement::get_unit_face_support_points()” returns Points; “transform_unit_to_real_cell()” requires Point as input. The dimensions of points in cells is

Dear Martin, Thank you very much! I have been working on making the test case not depend on our in house flowsolver's functions. I think that implementing Eq. 36 the "conservative curl" form would be sufficient. Yes this procedure sounds perfect to me, and I agree with the dimension of the
