Big values in ADRSolver (UnsteadyAdvection) with imported advection field
Hi,
I am having some problems with the ADRSolver (UnsteadyAdvection). I have an advection field obtained from simulating N-S equations around a bluff body until the steady-state is reached (Re=1). This advection field is provided to the ADRsolver in a .fld file.
The initial condition is provided in a .pts file and looks something like this:
After some time steps the solution field looks something like this:
As you can see big negative values are created close to the leading edge of the body.
I have tryed with different meshes, time-step size and number of shape function. I am glad to receive any advice. You can find the files needed in: https://imperialcollegelondon.box.com/s/24hgld3m7s76bxsh4ejrvqpfn7x0ypya
