Dear friends, I am trying to run Rayleigh Benard Convection (RBC) in Nektar++. I am facing problem in applying the buoyancy force (Ra*Pr*T). Is it possible to simulate RBC using Nekar++? I have attached my XML file. It would be great if someone would give comment on this issue.

Hi, Not sure if this is currently possible. One of the developers might confirm that? Regarding your configuration file, You need to have the Forcing tag outside the Conditions tag, see attachment. Also the BodyForce requires values for c1 and u. Finally I needed to remove c1 from the expression, for v - since it seems, that currently, you can not refer to a variable.

Dear Stanislaw, Thanks for your reply. As I can't use c1 to force the velocity field, that means, I can't do RBC. With regards Abhishek On Fri, Jan 19, 2018 at 12:07 PM, Stanisław Gepner <sgepner@meil.pw.edu.pl> wrote:
