Does HyperMesh support ABAQUS assembly?

Altair Forum User

I plan to use HyperMesh as pre-processor for ABAQUS. My model include several parts which will contact each other during the process. So, I will build an assemble.

However, in the list of ABAQUS keywords that HyperMesh-ABAQUS supports, I can not find:

*assembly

*part

Does this mean HyperMesh does not support assembly of ABAQUS?

Thanks in advance for your answer.

Regards,

Derek

Hi there.

I think it can handle parts and assemblies but it's an awkward way of doing it.

I suggest you work with flat deck, that is deck without parts and instances and assemblies.

HyperMesh generates flat deck by default. All you need inside hypermesh is a component for each part. The you create contact surfaces and pairs (use the contact manager). When you are done, you export the deck, you check it to be sure that HM has not left anything out and you run it like that.

hi fhumbert. what do you mean the word 'deck'? plate or shell?

by the way, i need to use abaqus to setup, a model exported from HM with 3 shell layer(surface connected) , how to do section assignment(the external 2 layers is in the same properties while the middle layer is of other properties)

my way is to set them in a composite shell. I can not select them separetedly while 3 layers comibined as visually 1 layer only.

I need some advice. thanks in advance

'deck' refers to the abaqus input file.

'flat deck' means no *Parts or *Instances are used to define multiple occurences e.g. using one bolt mesh and defining in Abaqus CAE 4 instances in different positions. In a flat deck, each part has unique element numbers and node numbers.

zhouhenry, I would recommend you start a new post with your question about composite shells.
