dear user,

if we use symmetry BC, should we have to double the forces to obtain the total force on the body.

Yes, in Fluent you have to double the force to obtain the total force when using a symmetry condition. The other option is that if you look at the force coefficients instead, use half of the reference area and that will give you a force coefficient for the entire model.

Just a side note, this topic has been discussed several times before on the forum. This is the same for many other topics. For a quick answer to your questions, search the forum and archives first. If you can't find what you're looking for, then post your problem.

Hope this helps, and goodluck, Jason
