Plot interface (alpha_water=0.5) vs time in ParaFoam
 

Hi Foamers,

I would be grateful if someone can help me with plotting alpha.water value 0.5 over time, so far I only know how to view this for one time step through using the following steps on paraview:

1) make counter at alpha.water=0.5
2) then use filter pointdatatocelldata
3) then plot over line

and this shows the alpha vs height however i would like to see height for 0.5 alpha for all time steps in one graph.

The help will be extremely appreciated, i have attached a photo to help visualize the issue


Kind Regards

Rimsha

Hi

I don't know if the graph including 3 axis, coordX, height and time, can be described in paraview.
But it must be possible to output csv files including coordX and height at each time.
I think you can draw the 3d graph by matlab or matlab clones, octave or scilab.
Csv files can be easily imported by matlab clones.

Hi

I created a python script that output water height as csv file.
I attached test case too.
Please execute following after ./Allrun
It will out put waterHeight.csv with some png files.
createGraph.sce is scilab script. You can make graph of waterHeight.csv with it.
Just try it.

interface height along a slant wall
 

Hello Kenyoh,
Thanks for sharing your test file.
I am doing capillary dominated flow in a V-shaped container where I need to obtain the contact line motion.
I was curious if if it is possible to obtain interface height along the slant wall using your files.
Thank you!
