Ansys Workbench 12 Assembly question

AI Thread Summary
In Ansys Workbench, users can combine two solids, such as a copper jacketed lead bullet, by either meshing them separately with contact surfaces or using a matching mesh on the interface. The discussion highlights the challenge of positioning and mating parts, similar to functionalities in SolidWorks. Users can import assemblies from SolidWorks but may struggle with precise positioning along specific axes. The solution involves using the body function and translation method to adjust the model's coordinates effectively. The user successfully resolved their issue by applying this method to create a unified assembly.

Hello,
I am used to use Ansys classic in my work. I just started to learn Ansys Workbench. I am modeling a copper jacketed lead bullet. I modeled the copper case the internal lead part.

Now I have two solids. Is there a way to mate them, and use them as one assembly, of solids?

Thanks

There are 2 ways. Either have them meshed separately and use contact surfaces to join them, or have a matching mesh on the interface. In the latter case I imagine it solves it without contact elements, but not sure. I don't have access to ANSYS these days, but here are some pictures from a tutorial -

Hello,
The picture in the tutorial you provided, the two bodies are already in contact, and you are defining the contact condition (such as no separation...), I tried the mesh, but I am not sure if that what I want. they body didn't move.

Here is a picture:

So, in solidworks I can just mate easily, and control them as an assembly, how can I do that in workbench?

Thanks

I can't see your picture, but I misunderstood you. Somehow I assume you can just import an assembly or a CAD geometry having several disconnected parts already positioned where you want them but not actually mated. It doesn't allow that?

I tried to import from solidworks, it works, but didn't know how to position it on a specific axis. I still think, I should be able to make them one assembly.

I will keep trying, hopefully someone can help me with this issue. thx

Solved! I figured it out, you create a body function, and use the translation method, it will give you x, y, z coordinates to move the model to.
Thanks
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
