Hello,
I want to simulate plastic pouch so as to check Inflation or bulge in it when,
1. Air is filled
2. Product is filled
I go through AIRBAG example but confused how to create pouch or airbag model in hypermesh. Please guide me
Hi,
Please find the video attached which shows Airbag Simulation.
Also, please go through https://www.youtube.com/watch?v=kCSRFss6GDE&list=PLQ7KUGFuVz4u5y3SvIEIU07427-gATaG6&index=5 which is a webinar showing creating monitored volume in RADIOSS.
Hope this helps.

Hello George,
Thanks for reference material.
Actully, I need a help to create pouch model first. Can u tell me how to create it in HM
For the pouch create a surface in the required shape and create the surface set for the same which you can recall in the monitored volume card.
to create pouch, do i need to create upper surface and lower surface?
If so, then how to give connectivity between these two?
Can You provide model file for the

Can you send model file for Airbag_simulation_setup
Do I need to create two surfaces, Upper and lower, to create pouch?
If so, then how to give connectivity between them?
how it become closed volume to use Monitored volume?

i'm sharing a simple pouch model. Please review the same.
Create a /SURF/PART for the same and create /MONVOL/GAS with this set. Please go through the webinar shared above which shows the steps for creating monitored volume.
How did you make it ?
I think this model was taken from an open web source. It will be difficult to create such a profile in HyperMesh as it is not meant for CAD modelling. We can only create basic profiles in HyperMesh with which you can try creating such a profile.

Okk
can you share me model file of the video u shared with me ( Airbag_Simulation_setup)
Please find the model files attached.
Hi, Please find the model files attached.
files are not supported. i am using Hypermesh 13.0 Block 130
Please try with this file.
Thank You.

Need more help as I proceed further.
I am done with Airbag simulation.
Is it possible to check failure of pouch material after air or mass flow in it?
There is no specific card or method to check the material failure.With the available simulation results user can check for the same in the model.
Can I use other material card instead of Mat law 19 Fabric?
Suppose i am simulating air balloon. I am filling air in balloon but after its capacity it get burst. If i want simulate this case, how can i do?
This is possible to simulate. You can try with a failure card in the model ( like /FAIL/TENSSTRAIN , which a strain failure model).
Else just define a burst pressure (Pmax) in the /MONVOL card. Pmax is the maximum pressure that can be reach in the volume. When this maximum pressure is reached then the pressure in the volume is set to Pext and no venting occurs anymore. This would be like bursting.
I will try for it.
Can I use other material for pouch filling rather than air. such as water or any other liquid product?
Yes, you can fill the pouch with liquid. You can try with SPH particles for the same.
But let me know what is your objective of the analysis.
Actully I want to check pouch shape formation after filling of product in it. My trail with air was successful. but now i want to try with liquid product
