WebThis book offers a concise and gentle introduction to finite element programming in Python based on the popular FEniCS software library. Using a series of examples, including the Poisson equation, the equations of linear elasticity, the incompressible Navier–Stokes equations, and systems of nonlinear advection–diffusion–reaction equations, it guides … WebMy second doubt is related to the association of fem-fenics functions with function handles. I tried to go through the code base in order to understand what to do, but I cannot quite get it. I expect that the function class should inherit from octave_function, but it is not enough, because if I type "handle = @function" Octave complains about ...
