Hello,

I am putting together a model of a Basketball in RADIOSS and have been using Example 27 to set up the airbag inside. I am not clear on a couple of the options for the airbag and was wondering if anyone can explain some of the airbag options – specifically how the vents and jets are set up.

It appears that there is both a jet and vent defined for the soccer ball. I would like to model the airbag with a constant pressure and no jet/vent and I wanted to know if this is possible and how the soccer ball defined in example 27 is different from what I am looking for.

In addition, I am not sure how whoever set up the analysis came to the following terms in the airbag set up:

MU
GAMMA
cpa

cpb

cpc

Avent

BVent

Thanks,

 

Tim

    Hi,

    I hope you are using Hyperworks commercial license.Radioss theory version of monitored volume contains required information. Please go through that which will help you to get more information about airbag simulation concept.If you are using student edition kindly let me know.

    Regards

    Hi,

     

    Maybe you can tell the solver that there are no jets using Ijet set to Zero.
