2017-05-17 Thread Ashkan Dorostkar
Dear all, I want to solve a system of equation for elasticity and I have an extra term in the my equations which is of the form -grad(b.u) here "b" is a vector of size DIM and "u" is the displacements with DIM components. I am a bit lost on how to express this with fe_values. Any help is

Hi all, I tried to compile my application with the new dealii 8.5.0 but it fails. In my program I user distributed triangulation and I get the error error: no matching function for call to ‘dealii::parallel::distributed::Triangulation<2>::Triangulation(ompi_communicator_t*&,

[deal.II] Spherical geometry surface integral issue

2016-11-22 Thread Ashkan Dorostkar
Hi all, I wrote a program where I use a HyperShell. Next, I produce the right-hand side of my system by computing a surface integral. In this Integral, I integrate a constant function times a basis function. One expects the resulting vector to be constant but I get different values in it. I
