i want to simulate Turbine using dynamic mesh and 6DOF in FLUENT. but when i started my simulation, always getting this error "6DOF object must have positive mass" and i am unable to further process my simulation.
kindly guide me how to remove this error?.so that i move further to simulate this problem.
Looking forward for your reply..

Since you don't mention a specific code, it's impossible to know what your specific problem could be. But as a shot in the dark, Newton's equations of motion don't really like negative masses. Try setting the mass to a positive value.

6dof, dynamic mesh, moment of inertia, turbines
