Motion Module

With CFdesign and the Motion Module engineers are able to visualize the interaction between flow and moving parts in your CAD models.

The CFdesign Motion Module allows you to simulate the interaction between flow and moving parts in your CAD models.

Several mechanical engineering applications require understanding the behavior of liquid and gas flows as they interact with solid objects. The CFdesign Motion Module allows you create a virtual prototyping environment by simulating the way components of pumps, fans, blowers, compressors, valves, and pistons interact and respond to prescribed flows. All the physical effects of the motion as well as the time-history are output for data review and to create animations for visual studies.

The combination of CFdesign and the Motion Module allows engineers to:

Understand the flow and temperature behavior of the flow as one or more objects move through a prescribed path at a certain rate.
Determine how much flow is required to set an object in motion, or bring it to a stop. Understand the path of the object, and even simulate it bouncing off of other objects.
View side-by-side design comparisons to determine appropriate spring sizes needed to prevent movement below a threshold flow.
Run scenarios to compute the bearing forces due to Orbital (whirling) motion due to shaft imbalance in pumps.
Evaluate the performance of turbomachinery devices such as pumps, turbines, blowers, and even multi-component devices such as automotive torque converters.
