Grid Point Force Balance Grid Point Force Balances Free Body Diagrams

Results Viewing Enhancements Simultaneous Display of Top and Bottom Surfaces

Scripting Language New Script Editor Supports vb form files Integrated graphical dialog box designer Customize Menu Commands Build your own menus to run scripts and program files Extended Functionality Over 100 new MSC/N4W functions implemented

Smart Results Averaging Option on Post Data Elemental Data now Provides “No averaging” Double-sided on shells “Smart averaging”, e.g., by property, layer, color or angle

Mid Plane Extraction Semi Automatic and Manual Tools to Create Surface Mid Plane Models

Creating Mid Plane Models Simple Case Fully automatic mid planes 14000 nodes, 6600 tetra, vs. 450 nodes, 425 parabolic shells (DOF 16:1)

Creating Mid Plane Models Moderate Case All but 2 surfaces automatic 35000 nodes, 19000 tetra, vs. 2100 nodes, 2200 parabolic shells (DOF 8:1)

Creating Mid Plane Models Real CAD Geometry “Automatic” created about 80% of needed surfaces Manual tools complete surface model in ~15 minutes
