Creating Two Separate Bodies in Design Modeller
 

Dear All,

In design modeller, I want to create two separate bodies(two separate parts) using different sketches. When I create a new sketch and make it 3D, the new 3D body and previous 3D body are known as 1 Part, however, I want them to be 2 separate parts.

Does anybody know how to do that.

Kind regards,
ashtonJ

Did you use the Search option? there are plenty of topics relating your question as your post regarding the "Revolve in Design Modeller" you could search before asking... Tutorials are a good way to get started with DM and the WB in general.

But I give you a hint, use "add frozen" when you create your second body.

Hi gweher
 

I have same question (as ashton) and I tried following options to make them separate two bodies, unfortunately din't work ;

1> add frozen ( i wanted interface between two bodies, so when i was setting physics in "Pre", it considered it only one body.

2>. using offset TO CREATE 2ND BODY in same plane, because both solid bodies are boxes and placed one above the other (with one common face) ,it again results in same problem, 1 part,1 body.

could you please point out my mistake??

Thanks

Danial,

The add frozen option should work. I don't have enough info from your post to help you further. Could you please add an image of your problem and what you are trying to model. Add the .agdb file :)

Hi
 

I am trying to make two bodies with one common face, infcat fluid and solid domains.i have atatched the pic.

Thanks

Hi Gweher
 

thanks bro, it seems i was desaling with unfinished business, i dint create second domain to make interface work.my baddddddd!:mad:

Thanks again

You are nearly there, just select the two parts, right click >form new part and then it should be fine.

Hi gweher
 

Thanks, though it worked without forming new part but still i learnt a new thing by forming new part , it could be done. cheers

Thanks again

Can I know how did you build two parts with common face with out using the form new paart,I have the same problem.
Thanks

In design modeller, I want to create and meshing two CUBIC that one of them is in the other one with separate bodies(two separate parts) using different sketches.
please help me.
I could create two cubic in geometry space, create larger one then create smaller one in different skeche with select add frozen instead of add material,but when I want to generate mesh ,some error would be created.

Does anybody know how to do that.

send me more details and picture

@msara
Instead of frozen, use "slice". That should do the job. Two separate bodies will be created.

Cheers ! :)

Thank you, Would you please explain more?

1) Extrude the first body using the first sketch
2) When you extrude the second body from the second sketch, instead of "frozen", try "slice"

The slice option will slice the body 1 as body from sketch 2 is extruded. Try this out and let me know if this works for meshing.

The issue is, with frozen, the two bodies are treated independently. The problem arises when one body is inside the another. When you choose frozen, the first body and second body both exist. So an overlap of volumes is created which causes the problem. Slice option extrudes body from sketch 2 while subtracting the intersection portion. So no overlaps :)

ya. if you do with frozen, you will have two independent body. But if you use slice option you will have two separate bodies. The interface will have src, trg and several wall regions. If you add to bodies using form new part, you will have interace common to both bodies. But you will have interface regions with
wall-part-fluid, wall-part-solid, wall-part-fluid-part-solid, and shadow regions.
Does anyone know why this happens? How to create common interface?

May I know the process / option to rotate the ''sketch "in Design Modeler?

i want to create solid cylinder in flow domain, while modeling should i use 'cut material','add material' or 'add frozen'?
please help

add frozen!

Try few tutorials, cuz all these things are covered in tutorials.
Plus you can very well try all 3 options and see what different things you are getting.
It will help in future!


Cheers

thnx i will look for tutorials

How can I create 2 or 3 part, 1 body.
In my case 1/2 body is inside the another. When I choose frozen, the first body and second body both exist. So an overlap of volumes is created which causes the problem. I also tried with the 'slice' option; it results same as 'frozen' option.

Please help....

Hi sazeda,

try Boolean to create subtract bodies and then preserve them.
Boolean
Operation: Subtract
Preserve tool bodies?: Yes

Symmetry/mirror feature in Design modeler workbench
 

Hello folks,

I created a 3D geometry. I would like to use symmtery/mirror application as I draw half of my domain. It seems this feature should be available in design modeler as it is a basic one but can not find it. Any idea would be appreciated!

Hi Hooman,

You dont need to create other half.
Run your simulation on current geometry just give Boundary condition of "Symmetry" on the symmetry surface.

Cheers
KAPI

Dear Kapi,

Thanks for the reply. Basically I want to use it inside a full 3d geometry and the figure I showed, is about 1/9 of the geometry. I would be grateful if you could still help me to mirror the geometry to both x and y planes.

Thanks!

Kapa,

I found it. I needed to use "mirror" from body transformation.
In order to copy the geometry you need to use "pattern".

Hi,

If you just want to see the results after running the simulation, you can use mirror option in fluent or in the CFD post to see the full geometry.

Azna,

No ...it is different...thanks for the time though...I posted the correct answer above.

"Add Frozen" and "Form New Part" is OK for a combination of solid and fluid bodies.
The interfaces would become "Coupled" automatically.
However, if the two bodies are of the same type (fluid or solid) and you need multiple cell zones, these operations would not work.

Following the tutorial found in the official site, I tried "Mesh control," but it said
"
writing contact_region-src (type interface) (mixture) ... Done.
writing contact_region-trg (type interface) (mixture) ... Done.
writing sliding-interface contact_region ... Done
"

Does it matter? and what's the difference? I don't know.
Could someone help?

"Add Frozen" just prevents intersected bodies from union. "Form New Part" just makes multibody part from bodies in order to create conformal mesh in AM. Designation of bodies as "Fluid" & "Solid" is mainly for visualisation purpose, fluid makes body transparent. I don't think it affects anything else.

How to create duplicate in ANSYS 16.2 workbench?

Please start a new thread, explain what you want to do, and include screenshot

You can also use Boolean function
- Create > Boolean : Select subtract , select the target and tool bodies; For the option preserve tool bodies -select 'yes'

Doing this will give you 2 separate bodies

Hi,

I have the same problem. I would like to create different parts ( different connected volume) but all being part of one body. I have not found anything on the forum.

Please Can anyone help me or tell me where I can find the answer?

thank you very much in advance

I am not sure what you meant.

You can have different bodies in one part n order to make a conformal mesh and let FLUENT take care of the interfaces automatically. If you make different parts, you will end up in a non-conformal mesh and you need to assign the interfaces manually.

Hi enayath,

thanks for your reply. I have got the geometry that I have attached. I was able to create a single body with different parts which should be connected. I don't have any problem if I want to create a simple tetrahedral mesh. However if I want to create a hexahedral mesh the mesh software keeps giving me an error and I do not understand why. Please can you help me ?

Thanks

I can not see the attachment.

sorry now you should have access

You need to play with the "settings". Try Multizone instead of automatic and set everything to fine instead of coarse. You may also need to decrease the min length or face size in the settings.

Yes i am also facing the same issue. Anyone know how to solve this ?
