Dear delii members
While modifying the material model in the step-44.cc, implementation of the
function *get_Jc_vol(). *I found the implementation in the code is
different than the formula provided. The worse part is that the solution
stops converging after correcting the implementation. I will be

Dear Deal.II community,
I have been using deal.ii for more than a year. I am solving the
reaction-diffusion problem, I am getting a bizarre runtime error in the
parallel solver. I am using PETSc CG solver. The error appeared after
parallelization. After 3-4 days of debugging, I found the error ap
Hi Shahab,
Please look at the following piece of code, it might be useful to you.
unsigned int n_face_q_points = face_quadrature_formula.size();

Dear dealii members,
While running step-44, 2d simulations I stumbled upon the mismatch in the
vertices of the quadrilaterals in the deformed mesh(please find the
attached image), I am curious if it's an artifact in visualization? How to
overcome this problem?
Thank you
Regards,
Navneet

Dear deal.ii community,
I am solving cardiac tissue problem, i.e. a time-dependent
electro-mechanical problem. In this problem electrical potential generated
from the pacemaker is taken care by a reaction-diffusion equation, the
mechanical response is an elastic contraction. A picture is attache
