Hi Alessandro, I've used the whitenoise mainly to trigger some tridimensional effects to some 2.5D simulations. The whitenoise is applied in the whole domain, not to a boundary since it's a force function. The parameters indicate the intensity of the whitenoise applied to the domain and the optional parameters, which I just used NSTEPS, is the amount of timestep you will have the whitenoise in your simulation. If you don't specify anything, the whitenoise will be for the whole running time. Hope it helps a bit. Cheers, Filipe On Wed, 10 Mar 2021, 13:10 Alessandro Alberto de Lima, <aalima@usp.br> wrote:

Hi Guys. Can you help me setting up a white noise during a few steps on m simulation? On the section 3.5.5 of the user guide I found this:
<FORCE TYPE="Noise"> <WHITENOISE> [VALUE] <WHITENOISE/> <!-- Optional arguments --> <UPDATEFREQ> [VALUE] <UPDATEFREQ/> <NSTEPS> [VALUE] <NSTEPS/> </FORCE>
What's the meaning of those white noises? I need to specify one for each direction on three dimension problems? I need to assign that noise to a specific boundary region (a wall, for example)?
Thank you. Alessandro _______________________________________________ Nektar-users mailing list Nektar-users@imperial.ac.uk https://mailman.ic.ac.uk/mailman/listinfo/nektar-users
