[deal.II] Calculation of local flux matrix in DG: looping over a cell's faces

Hello all, I want to calculate local flux matrix of a cell (in 2D). The algorithm I thought of is the following: [image: CodeCogsEqn.png] Within loop over cells: start loop over faces: re-initialize fe_face_values for current face calculate the 1D mass matrix add

Re: [deal.II] How to get the coordinates of dof with FE_Raviart_Thomas?

Dear Prof. Wolfgang Bangerth, The function fe.has_support_points() returns false. This means that the FE_Raviart_Thomas does not have support points. I think generalized_support_points are used for this type of finite element. For FE_RaviartThomas

[deal.II] How to get the coordinates of dof with FE_Raviart_Thomas?

Hi colleagues, With FE_Raviart_Thomas in 3D, the dofs are defined normal to the faces of each cell. For example, if we use FE_RaviartThomas (0), then in a cell we have 6 dofs defined o

Re: [deal.II] Create a LinearAlgebra::distributed::Vector from a LinearAlgebra::distributed::Vector

Dear Maxi, Did you try to call 'operator=' in the same line as you declare the variable? In that case, you still go through the (missing) constructor. It should work if you first declare the float vector in one statement and then assign in the next. We have this function: https://dealii.org/

Re: [deal.II] Create a LinearAlgebra::distributed::Vector from a LinearAlgebra::distributed::Vector

When doing that in my code, I get the error error: conversion from ‘Vector’ to non-scalar type ‘Vector< float,[...]>’ requested thus I assume I have to implement it myself... Am Freitag, 13. September 2019 17:53:37 UTC+2 schrieb Wolfgang Bangerth: > > On 9/13/19 8:39 AM, 'Maxi Miller' via deal.II
