Decrease diameter of cylindrical die
Hi;
I'm working on Hypermesh V13.0 and I have to mesh a cylindrical die oncoming from Solidworks ( Save as .STEP AP203).
On Hypermesh I want to decrease the external diameter of the die for exemple I want to mesh the die with this different diameter : Ø40 / Ø35 / Ø30 / Ø25.
This operation is possible with Solidworks but it's very long lasting because I have to mesh 14 die with four different Ø (--> 56 similary meshing).
And for my simulation is better if I have the same meshing on every diameter.
My approach for this is :
1st : I import geometry which is step file type : For beginning I import a die Ø40.
2nd : In 'GEOM' tool menu I use quick edit for decrease my Ø; for this I use the washer split with an offset value : 2.5 (to have 5mm on the Ø). After I supress the older lines with toggle edge (the older lines are on dotted line).
-->
And now I fail to mesh my new geometry (with F12 tool menu)
When I use (size and bias) :
Surf --> Display --> Mesh : The older lines (dotted) are meshing. -->
Surf --> By Window --> I select the lines which I want meshing --> The older lines aren't meshing () but I don't have mesh on the new external surface of the die
as the die is hollow.
--> OK //
--> External surface NOK
I think my approach for decrease the external diameter isn't good. I think I have to create a new surface but I just create news lines.
For your information I don't have the center of my die in hypermesh
I hope you understand my problem and you can help me.

Hi Udhay and Prakash;
Udhay : Where is the ruled option in HyperMesh V13.0 and how I can use this tool in my case ? I'm sorry I'm beginner in hypermesh !
Prakash : I have never used Hypermorph and I don't know how use Hypermorph; in Hypermorph which tool I can use ? morph constraints / morph volumes / morph / morph options / etc ... ?
Thank you a lot for you valued assistance !

Mr PAGADALA;
When I try to decrase the diameter thanks to Hypermorph>>Morph>>Alter dimensions.
I fail to select my domains I don't understand what is the domains !! For use Hypermorph; the die have to be meshing or I can use Hypermorph only with geometry ?
I must be successful for this operation because me and my working team are wasting time to decrease the diameter on Solidworks !
And the last question : Were are the tutorials available you mentionned ?
Thank you a lot !!

Hi Udhay and Prakash;
Udhay : Thank you for you reply; this solution works for my problems but when I include my HM model in Forge Luncher ; Forge Luncher doesn't mesh the model in 3D. I think my problem can't be resolve with GEOM tools.
Prakash : Is good for me; I have succeeded to decrease my model with Hypermorph; latter problems : when I decrease the diameter of my die the cylinder isn't decrease uniformly. I'm starting with a perfect cylinder and finally I have hourglass / double cone :

Not sure, Maybe you need to create more domains
Hi Jules,
You can use surface offset option to reduce the size.
In your approach, You can use ruled option to create surface between the top and bottom lines.
