Hi everybody,

i hope the questions i will post is not already here, but anyhow i did not find anything about it.

I am doing LES simulation at a cylinder flow at Re around 200.

Now i want to calculate the drag coefficient, the normal tool works fine, but i realised that i have to use the lesDragCoefficient and not the normal one.

If i try to compile the source LiftDrag.H it chrashes. The error is shown here later.

The next thing is that sgsModel is not defined at applications.../lifDrag.C, but lesDragCoefficient needs it. Can anybody help me?

Thanks Fabian

Hi, Fabin,

Have you solved your problems about "redifinition"?

Would you mind if you give me any suggestions if you have already solved it?

Thank you.

Bin
