Re: [Getfem-users] Export velocity gradient .vtk

[Michel Fournié]

Hello,

The gradient of 2D velocity field can’t be represented under vtk (it is not an export problem).

Generally from it you can compute the vorticity than can be plot.

Hi to everyone!

I computed a 2D velocity field U based on P2 elements. I computed its gradient with the function:

getfem::compute_gradient(mf1, mf2, U, V),

where mf1 is P2 element, mf2 is P1 element, U is the velocity vector and V is the vector containing the gradient which dimensions are 2*mf2.nb_dof() as prescribed by the userguide.

It seems to work.

Now, I would export the gradient field in .vtk. How can I do?

Thank you,

Nora
