hi I have a model to calculate frf for TPU materials between two metal plates
I would you like to convert metal plate from deformable to rigid how to perform it?
Hi
Check this video.
I checked but where only applied to hole on plate
how to applying to my model rbe element
Hi durukanbdilek
Similarly, you can switch on calculate node and multiple node option and select all the nodes of the plate which you want to make as a rigid.
The master node will be automatically calculated.

Hope it is clear
in my problem without using contact how to mesh ?
Can you please explain more about your requirement with some images or so
actually I have 2 main problem in model shared as above
firstly without defining contact and any dublicated node how to mesh the geometry
and I have not able to convert to plate rigid body yet
Unable to find an attachment - read this blog
My aim is to calculate Transmissibility FRF function and compare with experimental results
You can right click on Model Browser>> Create>> Rigid body. Make sure you go through the Rbody card on OptiStruct help before you create as it gives a fair idea on what is required for Rbody.
The file has been edited and attached. Also, an example file is attached which you can use as a reference
Since you have already given node to node connectivity between the honey comp material and plate, a need for an additional contact is not there
a last question to you about shell thickness
you know modelled top and bottom plate were modelled using shell
how a shell thickness ofsett selection used in model
also I opened edited file and saw nothing about rb
you can see 2 Rbodies created in the edited file. The above-shared video explains the creation of Rigid body using Radioss user profile. Since you are using OptiStruct user profile, you need to create likewise.
Also, refer online help for more details regarding shell thickness offset
I think you use newer version of hypermesh than mine therefore I cannot see them
Which version of Hypermesh are you using?
Altair hyperworks 14
I recommend you to update the version
hello can you shell - solid connection with rbe element if you say yes how _?
have a vibration isolation model, as below picture, blue, green and pink part represents shaker table, specimen and constant mass, respectively
I would like to assume blue and pink component as rigid how to perform it ? and Do I need to assign a material card to these components?
Hi ,
I think you can create a new material with high young modulus(E-Modul) value. This would mean the component is rigid.
or another method to save some calculation time, create a 2d mesh for the components(Pink and blue) and define rigid body for both of them.
