Check how we do it in the trubChannel example (see set_obj). Stefan On May 3, 2010, at 10:08 AM, [email protected] wrote:

Dear Neks,

for my case 'periodic channel flow around a sphere' I wanted to calculate the forces acting on the sphere. I've seen that there exists a 'drag_calc' subroutine in navier5.f. But as I understood I have to define my sphere as an object, that this works. Is this right?? Because until now the surface of the sphere is defined as 'wall'.

And if I have to define it as an object, I wanted to ask if there is an easy and fast doing this? Is there maybe a way doing this similar to defining the boundary conditions with 'set entire level', or do I have to add all the faces of the sphere by hand in prenek??

Thanks a lot for you time.
