This is a procedure we use to set the initial conditions in Lethe when the
initial condition is a complex function (for instance a Taylor-Green vortex).

Thanks Wolfgang and Praveen for providing suggestions. I have tried to
debugging this code for a while. I have attached this simple code on this

are using only C0
elements for the velocity.
If you are averaging the computed vorticity or obtaining vorticity by an L2
projection, then they would be continuous. Maybe your other codes are doing
something like this ?
