"Volume" Fill Mode Not Working for Horinzontal Tank (Cyliner with hemispherical ends) in DesignSPHysics

[rohith0698]

I'm trying to partially fill a horizontal tank in FreeCAD using DesignSPHysics. I tried the fillbox feature to partially fill the tank, but no fluid particles are generated in the case export—only boundaries appear. The expected result is a half-filled tank, but the fluid count is zero or extremely low (e.g., 9 particles).

Any chance you can zip up the file and attach it to the ticket ?

Hi Luzpaz,

Thank you for your response. I successfully filled the rectangular tank using the fillbox feature. However, I would like to monitor pressure at specific locations and perform cross-sections of the geometry. It would be great if you could assist me with this.

@rohith0698 please ask on the DualPHysics forum.

Okay. Thanks!

hey @rohith0698 how did you solve the problem. could you upload your file as i am trying to create a si,ilar model with a rotating motor inside a half filled water but somehow the fillbox does not work at all.

You can find documentation in the DualSPHysics package.

• examples/main/13_Pump: An example using a fillbox to partially fill a pump with water

Hey @Asdfg12345-tech, I have attached the case data file for your reference. FYI, I used FreeCAD to perform the fill box operation.

  Hello, I have a problem now, that is, at the beginning of the simulation, the water level was 700mm, but with the passage of time, the water level increased to 750mm, and then decreased to 650mm. What is the reason for this? The water density I set is calculated based on the water column height, which is 2 options. No water leakage, [etc.]

Hi,
Thanks for the reply. I wanted to ask how do i make the rotor inside move, what should be the parameters and consztants set of values cuy the gencase generates only 1125 particles with inter particle distance 0.01m and while trying to run the case, it alwayxs states an error occcured and to check if material parameters exist and peoperly defined

Also the fillbox still generates particles outside the box. What could be possibly wrong
