how to write udf to inflate a airbag due to the pressure load?
 

hi,
i need a help in writing udf to inflate a airbag due to the pressure load.
there is a inlet in the model and all remaining act as a wall boundary which is said to be deformed. please give any suggestion related to this type of problem if anyone knows.

thanks:)

I don't think this is possible in FLUENT

Deformation phenomena quite complex, and also need to consider

structure.

But FLUENT is powerful only in fluid motion.

So, using the fluent only calculate the pressure profile and

using the profile calculate deformation of air bag? like this?

Sorry for poor English:(

I can confirm what Bluenails already said. This will not be possible in Fluent as a single programm.
But have you thought about making a structure coupled build in Ansys Workbench? This could work somehow ...
