Problem with sliding mesh
I'm trying to simulate a wind turbine with the "Sliding Mesh" method. I have divided the fluid in three zones: front, central (which rotates and where the blade is located) and rear. I also set two interfaces between the different zones and the periodicity conditions on both sides in order to simulate only one blade and not the whole propeller.
I attached some photos to show you the problem I have. It can be seen that it works perfectly from the first step until the step 47. At step 48, and I don't know why, the central zone changes the rotating axis (the initial one is the X axis), and it crashes with the rear zone. Something similar occurs at step 82: it changes the rotating axis to a different one at step 83.
żAny idea about why this problem appears or how to solve it?
Thanks in advance!
I have removed and done again the mesh, set Fluent conditions and launched the preview of the mesh motion, and the problem doesn't change :confused:
What can I do?
trackindg water surface in wave tank
what s the meaning of selecting sum in "define surface monitor" for "Phrases" , "volume fraction" . I have a 2 phase domain, primary phase is air and secondary phase is water. I am going to track surface changes for water, in internet i read that I have to select sum when i intoduce monitors/surface/surface monitors/define surface monitor.
my case is a Neumerical Wave Tank.
please help me.
