By that you mean drag and lift? I only have that in the monitors option, I don't have spin vector, drag is in x=1 and lift is y=1

In the boundary condition panel you can set something like spin vector or spin axis orientation? If for example cd is in x-direction and spin axis is in y-direction (which you should check) then cl should be in z-direction.

I put an image of the orientation of the mesh attached

In the boundary condition for the ball:
I have motion rotational and then a rotation-axis origin which I defined 0 for x,y,z
and I have rotation-axis direction in which I have 0 for x,y and 1 for z.

In the monitors I only have active the residuals, drag and lift. In the drag I have Force vector x=1 and in the lift I have force vector y=1,

I think it's ok...

Yes that should be ok.

Hmmm ... this is strange ...

Could you perhaps upload your case somewhere, such that I can have a look at it?

I have a question regarding the Magnus (or lift force) it's about the expression that is used to calculate the Magnus force, I've found 2 of them and don't know which is the right one
is it:

Fl=1/2*cl**A*v^2

or

Fl=1/2*cl**A*r**v

I'd really appreciate the help

They are both correct.

However the upper definition is more conventional. This will give the correct force if you use the cl from FLUENT.

Take care that A is the projected area of the sphere. ( \pi r^2 )

hello
I have another question, If you see the image I posted, it is a normal football where I did the analysis, I wanted to see more the edges and pattern, like this second image I found on the net
can anyone help?
best regards
