Re: [deal.II] Setting smooth coefficients in space

Dear J-P and Wolfgang, Thank you for your answers! As I see the actual problem is to define a step function for material parameters. In FEM simulations mesh is often aligned to the problem`s inner interfaces (like in a "Better mesh" extension of step-6). Is it possible to define for such a case

BTW, the element in bottom left corner is too triangle for good FEM. To solve this providing an additional element inside the curved boundary looks to be a common approach, you can find more details here http://dealii.org/developer/doxygen/deal.II/step_6.html#Abettermesh среда, 21 сентября 201
