[deal.II] Re: weak form for advection-diffusion equation

Thanks for the response! I've read some articles that the governing equation (advection + diffusion) is unstable when it has large Peclet number. (Even though it has diffusion term.) What I am concerning is that it is how to imply SUPG stabilization method in deal.ii., because my future

@Timo: Thanks for the confimation and feedback. I needed to do some adjustments to candi to get parmetis to run, but a combination of https://github.com/dealii/candi/pull/33 and https://github.com/dealii/candi/pull/32 should now be able to automatically install deal.II on most Cray machines.

Hello, I am using xubuntu 16.04 as a newbie and trying to install deal.ii. At the stage of building the error shown as below emerged unfortunately. I tried the same way with a different release (i.e. deal.ii-8.5.0) and faced with the similar problem again. I checked another replies to fix it,

Re: [deal.II] Compute jacobian at point (no quadrature point)

Felix, also, if the point you want is not a quadrature point, you can exploit the following trick: Point my_point_in_reference_cell; std::vector quad(1, my_point_in_reference_cell); and then you can initialize an FEValues fev(fe, quad, update_inverse_jacobians); This will give you
