History-based Solid Modeling
FX+’s Shape Evolution service enables user to change the
model parameters (dimension & location) at any time.
This service carries out the dimensional analysis and/or
re-production of similar models very easily.
This works even when FX+ is re-started or model is re-opened!

Auto Surface Mesh Generation
FX+’s surface meshers strive to generate offset elements near
boundary for the best quality.
FX+ provides a number of controls to manipulate mesh density
and generates optimum meshes required in practice.

Auto Solid Mesh Generation
FX+’s Tetra Mesher is capable of including holes, curves and
points that are present in/on the solids.

Pre-processing Input
Full Support of Load and Boundary Conditions
Loads and boundary conditions can be applied to geometry or mesh.
Loads and B.C.’s applied to geometry are independent of mesh.
They are valid even after shape evolution or remeshing!
Loads and boundary conditions can be verified and modified freely in
graphic window, table window, and property window.
Time/temperature/coordinate-varying loads can be defined in tables, and
displayed in various graphs.
