I have a horizontal piece of equipment that has three supports (not equally spaced), an inlet & outlet connection, and two segments of different OD dimensions. We are planning to not anchor this so the connected pipe will be moving it around. The weight of the equipment and the center of gravity is shown on one drawing. I can make a general model of the equipment - can I use the center of gravity to place the weight and how would I do that?

Hi Smith

If there is no anchor support in the equipment we can avoid anchor or virtual anchor from Caesar model.
Since your present equipment is non symmetric I suggest to model both the way & compare the result.
1) Model equipment & support with zero rigid body & put total weight at centre of gravity with 1 mm weight rigid body.
2) Model two portion with specified pipe diameter & thickness & check Caesar output ( how much equipment weight it shows). Check out result.

Even if equipment support is only resting type, I would prefer to model equipment with rest + guide to get more rigidity in the equipment of the Caesar model. Definitely equipment will not provide similar kind of flexibility as pipe gives.
