|Subject:||[ESPResSo-users] WG: poiseuille flow with linear part at first and last grid|
|Date:||Wed, 20 May 2015 12:00:15 +0000|
I have run the script poiseuille.tcl from the espresso samples. The result is a flow which looks like a poiseuille flow, but with a linear part in the first and last grid along the x, y and z axis.
I have put an picture in the appendix, which shows the poiseuille flow with different conditions than in the script poiseuille.tcl. There are agrid and tau 1 and delta_x=0,25 and delta_t=0,05. Is there any way to get a full parabolic poiseuille flow without the linear parts?
Kind regards and thanks for help,
