Hi all,
I'm trying to work some adjoint optimization into my workflow, and I haven't been able to get the optimized mesh out of Fluent in any usable form. Does anyone have any solutions to this?
Here's what I've tried so far:
Code:
file/write-boundary-mesh
A test mesh has zones looking like this:.
Code:
Zone sizes on domain 1:
   18048 mixed cells, zone  4.
   52390 mixed interior faces, zone  1.
    2688 quadrilateral wall faces, zone  5.
     282 mixed velocity-inlet faces, zone  6.
     282 mixed pressure-outlet faces, zone  7.
   19630 nodes.
I try to pull this into FEModeler in Workbench 16.0, and it throws this error:
Code:
Invalid Fluent mesh format. This mesh cannot be read in FEModeler (in particular, polyhedral elements).
Once I'm in FEModeler I know how to manipulate the mesh to get a parasolid out, but I can't seem to massage the .msh file into something FEModeler will accept as input. All I want are the wall faces on zone 5.
I found the Fluent .msh file format here, and my output mesh looks like this:
Code:
(13 (0 1 d95a 0))
(10 (0 1 cb2 0 3))

(13 (5 cca7 d726 3 4)
(
4 3 2 1 0 0
6 4 1 5 0 0
8 6 5 7 0 0
a 8 7 9 0 0
c a 9 b 0 0
e c b d 0 0
10 e d f 0 0...
It has additional zone blocks for 6 and 7 for faces as well as a huge block for the fluid volume.
The face section
Code:
(13 (5 cca7 d726 3 4) (...
doesn't seem to have well formed coordinates, but I'm not sure how to correct them.
Suggestions? This has been a bear. All I want is a model I can import back into Solidworks and begin to adjust for machinability.

Hi, all

In current release you can use TUI command:
/adjoint/design-tool/design-change/export-stl
