Hi all,

I am trying to mesh a relatively large geometry with small element sizes in Fluent Meshing. Unfortunately I run into the following error:

> ; Shrink wrapping /objects/wrap/wrap bypass () collectively wrapped-mesh shrink-wrap mp hybrid 1
initializing octree...
the existing Size Field will be used.
refining octree...

Insufficient memory to refine octree for the given size requirement.
Please increase the memory limit from Controls dialog box (Category: Shrink Wrap) or use a coarser size-field and try again
Error: 0 : Increase the Max Octree Memory.
Error Object: #f


Also the Fluent Meshing user's guide suggest to increase the octree memory in this case. When wrapping large, complex geometries with small mesh sizes, you may need to increase the memory allocation. From the Display → Controls menu, select Shrink Wrap in the Categories drop down list, and specify a new value for Max Octree Memory.

So I am trying to increase the allocated memory, which is very easy to do in the GUI, but unfortunately I only have access to the TUI and I can't find the corresponding TUI commands to do so.. Does anyone know how to do this in TUI?

Below are the GUI commands
(cx-gui-do cx-activate-item "MenuBar*DisplayMenu*Controls...")
(cx-gui-do cx-set-real-entry-list "Controls*Table1*Frame4(Shrink Wrap)*RealEntry2(Max Octree Memory in GB (38 M octants/GB))" '( 96))
(cx-gui-do cx-activate-item "Controls*PanelButtons*PushButton1(OK)")
(cx-gui-do cx-activate-item "Controls*PanelButtons*PushButton2(Cancel)")

Or does anyone have any suggestions for creating different meshes for a mesh independence study?
