My FSI simulation (pipe-flow)

vitorspadeto · September 24, 2014, 18:24

This is my simulation using FSI. See the files in this link to download it:
http://www.filedropper.com/pipe

I used the solver inside EXTEND-BAZAAR (foam-extend) to FSI simulation. See the directory:

I used this case (3Dtube) to create my simulation. But the result was not as expected.

The deformation of the tube (due to the pressure of the pulsatile flow) should be higher. The deformation of the tube was approximately 0.01cm as should be of the order of 1cm. One could look at the files and try to find where is the error?

*I consider the fluid with viscosity of 0.0035Pa.s divided by 1050kg/m³ (density of the flow) = 0.0000033333333 m²/seconds

there in the archive( http://www.filedropper.com/pipe ) a pdf document that explains the conditions and parameters that I wanted to use in my simulation. you must read it initially. Unfortunately the compressed file you download need to change, "solid" link in the fluid/constant directory and "fluid" link in the solid/constant directory must be recreated because they became a folder in the process of .zip compression...

sorry for posting in this area, but I believe that in other areas of the forum no one will know answer....
