I have created a box of air surronding the cylinder- do I have to keep the cylinder in the model- or the air volume will be sufficent. the cylinder is a moving object - I do not know how to set up the geomety - shall I have a solid for the cylinder and the fuild for the air and define interface between them please help thanks agian for all of your helps
