Client – Where the user can set up simulations, input commands, and manipulate views for

  • analysis. Generally the

GUI workspace Server – Executes the commands set up by the user. 6

Yes No Combine Parts X Combine Surfaces X Surface Repair X Splitting Surfaces *(see notes) 3D CAD Models *(see notes) Create part X Composite Parts X Boolean Operations X Retesselate Parts X Apply Tags/Filters X SURFACE REPAIR  2 Users cannot use surface repair mode at the same time

  • “WARNING: Already editing

surface, shutting down repair session”

  • The client that gets closed

will often have errors in the scene that was used

SPLITTING SURFACES  Can be done with multiple clients, but with some issues*

  • While splitting by patch, the

scene only highlights the part surface in the client which selected it and the part surface number will not be removed from the edit window

  • User 1 and User 2 can select the

same surface to be split by angle, but the operation done last will split a different surface

3D CAD MODELS  Can be used by both clients simultaneously*

  • Different operations can be

performed simultaneously

  • 1 scene is shared by all users
  • Operations open at the same time

will be combined, not overwritten  If features are being edited by user 1, only those listed below that operation can be edited simultaneously by user 2

  • Macros can be created and saved by each client
  • The macro for each client will be different
  • Macros are saved from client rather than

server

  • Macros set up in a collaborative simulation

cannot be played if operations not yet executed are called.

Viewing Scenes

Highlighted Parts

  • Selected part is highlighted for each client
  • Have only the working scene open in each client

Split Surfaces

  • Surfaces hidden in a scene can be seen when that surface is split

(only specific named surface is hidden)

  • Each user should include only the necessary parts in a scene, rather

than hiding other parts

Surfaces

Surface Repair

  • Avoid opening surface repair mode when it is in use by another user
  • Use Boolean operations (unite, intersect, merge) for other surface

repair

  • Parts must be closed and manifold

Splitting Surfaces

  • User 1 cannot split a surface that is currently open in surface repair

mode by User 2

  • False split surfaces will appear in the tree, but will not

correspond to any geometry

  • Surface Repair mode will be closed for User 2

Mesh Generation

  • Only values can be changed while the mesh is being generated. No

new operations can be executed

  • Possible Improvements – Enable other non mesh based operations

during mesh generation (post processing setup, continua setup, new shape part creation) Surface Repair

  • Only one user can use surface repair at a time. All other non mesh

based operations can still be done while surface is being repaired.

  • Possible Improvements – Enable surface repair for different users when

used on different parts Macros

  • Macros will only log processes done by one client
  • Possible Improvements – Record macros on server so that all

commands are logged and can be re-executed
