Dynamic Mesh
 

Hi
I want do modeling that the body move at one direction by layering method from dynamic mesh in FLUENT 6.3. I use the same UDF that be in User's Guide of fluent. There is one problem during simulation of this case, that the behind cells of body do not split correctly and those stretched, while the cells in front of body, colapse correctly. Despite i change the split and colapse coefficients, do not vary in solution. I will thankful everyone that help me for this problem.
Regardly

try to put spring factor to 0.0.

I use the Layering method in Dynamic Mesh with structural mesh.
Are you tell that i select spring method plus layering method?

Time plot in fluent
 

Dear friends

I m working with fluent 6.3 ,I modelled a wave tank in fluent and I want to get time plot about the history of wave elevation at a specified point for example x=7.5,y=0.5 (in fluent I accentuate this matter again) in a wave tank with these dimensions: L=15m, H=0.8m for a detemined time domain which is smaller than wave tank modeling time domain.

if any friend know, plz guide me and give me the tips and tricks about it.



With kind regards.

it worked?

tracking water elevation in NWT
 

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.
