Depth varying in 2DH
I don't know how to implement in the pil file the varying depth in the 2 DH of an pen channel flow

Re: Depth varying in 2DH
As a suggustion, can you not make a fat channel and block out the parts you dont want?
|
Re: Depth varying in 2DH
not i can't make a block, it is a variation like a stairs generate a variation of the depth tahnks
|
Re: Depth varying in 2DH
You could use lots of blocks to make stairs

Re: Depth varying in 2DH
if it is a varying topography, is it fan the adequate command and how to use this?

Re: Depth varying in 2DH
Perhaps I misunderstand you?
1/ You can make a solid volume STL file and import this onto a cartesian grid using the PARSOL cut-cell method to cut this object shape from the background grid. or 2/ Use a Body fitted grid or 3/ Represent the depth varying through blocking out a cartesian domain with object shapes from the library of such objects, wedges, rectangles, arcs, whatever. |
Re: Depth varying in 2DH
If you are using the hydraulic analogy, you can use porosity fields, with a porosity field, you can simulate flows with different depths, at least it worked for me.
With porosity fields ive simulated bumps or obstacles for inducing an hydraulic jump. |
Re: Depth varying in 2DH
Please, if you have any document about analogy, can you please pass it or explain me thanks
