Meshing of Assembly

Hello All,

I am very new user and recently started learning about Hypermesh 12.0

I am looking for help/support on meshing of assembly (Hex Element). For a reference I have attached image of assembly and step file.

Questions

1. How do I mesh components? Shall I create .hm file for each individual part and assemble them?

2. As of now I am not worried about providing contacts/Boundry conditions/Load cases. I am just looking for mesh of assembly. But at a same time I am looking for elements to match at adjacent faces. For example Face elements of shaft and bushing, face elements of bushing and housing and Face elements of housing and bottom plate should match so that later it becomes easy to provide contacts.

3. How to manage large assembly in hypermesh?

4. It would be great help If someone can upload video of assembly management or how to deal with assembly in hypermesh

Appreciate your help in advance !

Hi @jagdish_mak

Is there a reason to save different components as different files(parts)?

You can do the meshing in a single file as well and can carry further modelling.

Hello Prakash,

Thanks for reply !

I agree with you that meshing for this assembly can be done in single file. And that's what I want to understand when & how to make decision to carry out meshing in single part and assemble or carry out meshing in single .hm file for whole assembly.

If carrying out meshing in single .hm file is the option, than how to handle meshing of large assembly ?

Also can you help me to understand about what how to match face elements of adjacent faces. In my case it is very simple, one can even calculate and arrange elements. But in case of complex irregular geometries it becomes difficult. Is the Mesh Imprint solution for it?

If any of the parts/components in your assembly are re-usable, then it is a good idea to split into different files.

Managing the data is important. Arrange the elements in different components and this makes life easy

There are lot options available in HyperMesh say like Imprint, copy, reflect elements and assign the same in a different plane etc...
