I have prepared a step file of the drone propeller and with it the boundary condition for air around it,
And uploaded in mesh mix-match and further created another Cartesian co-ordinate for that box,
I had tried to create separate mesh refinement zones for all the objects including the Cartesian box, the problem that is there is when i start to mesh the objects the propeller which was interpreted as solid_0 doesn't get included in the meshed parts.
And so the propeller fluid dynamic simulation cannot be done.
Please require help in this matter
