[deal.II] neumann boundary condition for a vector valued continuous FE equation using matrix free

2021-11-18 Thread Ray Mclaren
Hi, I am solving a vector valued equation (mechanical equilibrium) using dealii's matrix free infrastructure. Although the library has several examples on how to apply neumann BC using matrix free most are either scalar equations and using DG methods. Is there an example of continuous

[deal.II] Multi-physics implementation

2020-09-21 Thread Ray Mclaren
Hi, I have a question regrading multi-physics problem implementation. I am developing a program that will solve the steady-state thermal conduction (laplace) first and then the allen-Cahn equation. both of the problems are solved on the same mesh, however due to the nature of my specific
