Hi Bruno, Thanks for sharing your experience, I am very much encouraged. I will have a play of systems you recommend, and hopefully in a few weeks time, I would be all set up. Thanks for your time, and my question is fully answered. Martin On Thursday, 22 July 2021 at 8:52:57 pm UTC+10

RE: [deal.II] Matrix Multiplication

Hi Jean-Paul, I revisited the code gallery example “The deal.II Library: The 'Quasi-Static Finite-Strain Compressible Elasticity' code gallery program (dealii.org)”. It seems I just need to modify two functions, i.e., getJc(det_F, b_bar) and get_tau(det_F, b_bar) if I want to implement the St.

Here *n_dofs = 320* and so *system_to_component_index()* does not like to have an argument i>=160 and throws an error. How come n_dofs=320 in this case ? I was expecting 2 interfaces * 2 nodes * 40 components = 160 dofs, unless I am considering all the interfaces of the cell at onces in

Dear Michael, Although this BDB form is, as you say, ubiquitous in the literature, it is a consequence to using global scalar-valued shape functions everywhere as opposed to vector-valued shape functions that we support. So it falls out of the way that the finite element Ansatz is defined for

Hello everyone ! I have (another) a problem in my code. I am trying to mix *step-12* and *step-31* for my project. I want to solve two coupled equations (named *eq1* and *eq2*) that I am solving in parallel just like in *step-31* but for one of them I am using the Discontinuous Galerkin

Hi Martin, Multiple IDEs work very well with Deal.II. As long as your IDE has good CMAKE support, compiling deal.II with it is a joke. Some IDEs which me and my colleagues have found work very well in the present case: - Jetbrains CLION (this one is not free, but for a reason I don't understand
