Hello,
When I used svFSI to do a simple cylindrical model simulation, I input a steady flow (in mm/s) into the inlet (Area = 12.49mm^2), as shown below. But the flux in the result file
B_NS_Velocity_flux is about 7.75. I am not sure what is the unit of flow here.
Code: Select all
Add BC: inlet {
Type: Dir
Time dependence: Steady
Value: 1.249689
Profile: Parabolic
}

Any help will be appreciated.

Hi Lina,
The svFSI solver has no implicit units although some default values (e.g. density) use CGS. You just need to make sure that your mesh units are consistent with your parameter units. Note that you can scale your mesh to match your parameter units using the Mesh scale factor parameter.
Cheers,
Dave
