How to give boundary condition for rotating frame
 

Hi,

Heartly welcome to all fluent users.

i am facing a problem in giving Boundary Condition.

please help me to solve this.

problem is i am having a blade in a cylinder.

i want to simulate the condition while blade rotates.

how to carry out this problem.

thanks san

in bondarie condition

1- SEY FLUIDE 2-OPEN motion typ choose ( moving reference frame) 3-put your valu in rotational velocity (speed)

do u mean that, do u want rotation of solid blade inside the cylinder in steady state?

if it is like that, in bc panel, for the solid u select moving reference frame - give rotational velocity and direction, for the walls around that blade, select moving walls and give the same values for rotation.

i think this will work, check it.
