Symmetry and boundary conditions
Hi,
I have values for mass flow rate for flow in a pipe, from which I calculate the inlet velocity. I'm using symmetry, to reduce computation time, therefore i have half the domain of the pipe. My question is - do I apply the full, calculated, inlet velocity as the boundary condition or do I halve the inlet velocity, because of the half pipe, and then double the values of the results? Thanks in advance, Eric. |
Re: Symmetry and boundary conditions
Hi,
no reason to half the inlet velocity, as you are using a symmetry and indicated it in your BCs. cheers David |
Re: Symmetry and boundary conditions
I agree with David.
You have to specify the real velocity inlet. |
boundary condition (symmetry vs periodic doubt)
Dear friends,
i am doing 3D wing analysis, i have doubt on boundary conditions in fluent ie both symmetry and periodic, anybody have the answer please let me know briefly,for what kind of purpose to use symmetry & periodic boundary conditions, please tell any example with problem. |
