Organizing Components into Multiple Assemblies

Altair Forum User

Hi,

 

According to the Hypermesh User's Guide: while it is possible to organize components into more than one assembly, it is not recommended. Shown below is the direct quote from the guide. 

 

'Components can be organized into more than one assembly.  Therefore, components are not mutually exclusive to an assembly.  To organize a component into more than one assembly drag and drop with the control key depressed.  In general it is not recommended to organize components into multiple assemblies if it can be avoided.'

 

 

Can anyone go into depth why it would not be recommended? What are the drawbacks? It seems like a good way to create iterations of a design by including/excluding one or two components between assemblies.

For any interested,

 

One problem I have run into while exporting individual assemblies to a solver such as LS Dyna is the contact cards. I could work around this by creating contacts for each assembly. It is possible to select/deselect contacts to export but it was kind of a headache to select the assembly and then go through and select the necessary contacts for that assembly.

 

I think this is the reason why the user guide says it is not recommended to organize components into multiple assemblies.
