How to handle a uniform coating over a complex object

How to handle a uniform coating over a complex object

How to handle a uniform coating over a complex object

(OP)
I have an ANSYS model of a fairly complex assembly and need to assess the thermal protection afforded by a uniform thickness of low-conductivity RTV-like material from a rocket's blast plume.  Does anyone have an idea how the RTV can be modeled WITHOUT adding the coating to the geometry?  This would save dozens of hours of CAD time.
TIA for your thoughtful responses!

Hello, Bruce!

You could the followings:

1. Select areas where coating exists. I assume those areas are exterior areas of some volumes already meshed.
2. Use SHELL131 or SHELL132 (depending of the type of element used for solid modelling). These elements allow for through thickness conductivity. Also, define a material for coating.
4. Mesh the selected areas using the element type described above.

Success!

Juzz-
I'm using Workbench Rev. 11.  Does that matter?

Bruce,

My advice is available when using classical ANSYS (not Workbench).
I have no idea if is applicable in Workbench. Maybe other members of forum could help.

Kind regards,

Juzz

Hey guys.  Any ideas on how to do this with Workbench Rev. 11?

Hi

In Workbench this can only be done with using a snippet(Commando block).
Make a named selection of the areas where you want to aplly the coating. Name them for instance Coat_Surface
Something like this should be in the snippet

*get,et_max,type,0,num,max
et,et_max+1,shell131
mp,?,et_max+1,?
sectype,1,shell
secdata,?,1,?
type,et_max+1
mat,et_max+1
cmsel,s,Coat_Surfaces,node
esln
esurf
allsel,all
