Forces/Moment in CFX-Solver
Hi all,
I have a quick and easy question that i guess i want to confirm. In cfx-solver, under 'monitor->forces->normal x-direction', does this represent the resultant drag force on the body? Also what is the unit of that force? Same question applies to moment. What unit does CFX-solver uses for Moments, because the y-axis just show them as 'variables', with no units shown. Also, under the 'monitor' option in cfx-solver, there are two kinds of forces. One is 'Normal' and another one is 'Tangential', does anyone knows the difference? I know the meaning of the word but what does it physical means when it is refered to the forces? Thanks in advance, Maga |
Re: Forces/Moment in CFX-Solver
Hi if you want to monitor forces and moments on your body I suggest you to create a monitor in cfx pre using functions "force" and "torque". The first give you the force that fluid does on the surface long a specified direction. The second give you the moment long a specified direction. Be careful if you want the moment in y direction you have to type "torque_y()@Surface" where Surface is the area on which you want calculate the moment.
I don't know if monitors about Normal and Tangential Force and Moments give you the value you are looking for! Regards |
Hi Both,
Normal forces about X is regarded as the axial forces and that i am sure, but what i dont know is normal forces about Y and Z and also tangential forces about X, Y and Z, if you guys know anything more pls let me know as i am interested in getting radial and tangential forces but i am confused.
