Flange hex Mesh automation...

Pandurang

Dear All,

is it possible to automate hex mesh for Flange (see ref Image attached) with washer around holes (holes may more than 2) .

 

Any idea...Please Suggest...

yes,

1) find holes

2) washer split holes

3) automesh upper faces

4) drag down to generate hexas

Hi Tinh

 

hm_holedetectioninit
*createmarkpanel surfs 1 'Please select surface'
hm_holedetectionsetentities surfs 1
hm_holedetectionsetholeparams hole_shape=31
hm_holedetectionfindholes 1
set n [hm_holedetectiongetnumberofholes]

 

I using these commmands to find surface holes...but Not getting single hole through this..am i doing wrong?

 

tinh

No, you aren't

Select upper surface only

It will return n=3 holes

Pandurang

yes i am selecting upper surface only..but get nothing..

tinh

Maybe lack of hm_holedetectionend

just follow example in hm reference help

Pandurang

Same example script is used but getting : Holes not detected.

tinh

Which hm version is it?

Pandurang

2017.2

it's used for 2d only, this means your surfs must have red boundaries. when selecting the surfs, 'duplicate' them before 'proceed'

First thanks for help....

Up to second point is done ...Now how can automesh the face..?

 

Means how to use  *set_meshedgeparams and *set_meshfaceparams....

Hi

The usage is in hm reference help

Or you can use *defaultremesh

Except 2 washer surfs where you need to unify inner and outer density
