Reply To: Taylor Green Vortex Velocity Initialization
Dear liu,
thank you for your post.
The best example to start would be examples/turbulence/tgv3d/.
I suggest to change the 3D functors to 2D, and remove all the lines you do not require.
The intialization should also be simplified, such that only defineU and defineRho is left.
The velocity field for u_0 is constructed as functor and then passed to defineU.
The pressure for p_0 (given for example in the book of Krüger et al. (2017)) is constructed as a functor, then transformed to density and passed to defineRho.
