Page 7: Morph

Purpose: This interface is for morphing of an existing mesh. Two methods are available: Morph and Map 8L.

Morph - This method works by constraining the parts to be morphed (Morph nodes) within a solid hex mesh (Con. Ele.). Once Constrain has been activated, the hex mesh can be transformed in any way, and the Morph nodes will follow. The nodal coordinates are transformed based on their relative position within their containing solid element. Thus in order to make more precise adjustments, a finer solid mesh should be used.

Map 8L - This method works by mapping the parts to be morphed between a set of 8 line (4 Source and 4 Target). It is similar to the first method except the solid mesh generation is done transparently and automatically.

Controls:

  • morph panel
  • Constrain in Solid
  • cb Sel Con. Ele. - Select solid elements acting as constraining boxes
  • cb Sel Morph nodes - Select nodes to be constrained in elements

Constrain
 Constrain nodes inside selected elements

  • cbc Show con. nodes - Display constrained nodes

Unconstrain
 Unconstrain all nodes
Update
 Force an update for the position of constrained nodes

Done
 Exit Morph Interface
