Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved. Profile The profile is defined by a set of nodes selected by the user. The shape of the face is defined by a polygon using the selected nodes in a sequence. This feature allows the sweeping of the profile. Once a profile is created, it can be saved and imported for latter use. Bolts, liners, valve seats can be defined using a profile and stored.

Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved. Profile Using the Start / End / Restart buttons, select a set of nodes. Specify the angle of revolution and the axis about which the profile is to revolve. Enter the number of elements and the mesh size.
