[Nektar-users] Bug in LDG

Dear all, Whenever I use 2 or more equations with different types of boundary conditions for diffusion, convection-diffusion with LDG I obtain something weird. For example, a solution obtained using the attached file is just random noise. However, when I run problems separately or use implicit diffusion advancement (discontinuous and continuous), there are no issues. What is the reason for such behavior? Is there a way to fix this? Thank you, Aidyn
