Flex wizard helps the user to design the valve system with nodal flexible bodies.
•Flex wizard supports two functions such as Body Swap and Connection.
•So, given a complete valve system with only rigid bodies, you can swap several rigid bodies to their nodal flexible bodies and define their flex contacts through Flex wizard.
•In Body Swap, the FE input file (NASTRAN or ANSYS) should be prepared so that a nodal flexible body may be exactly imported at SPM of its rigid body.
•In Connections, Flex contact is automatically defined according to what body is swapped.
