Tightly folded Inflatable structure deployment simulation possible in comsol ?

Hi,

We have a problem where we need to simulate the deployment of a tightly folded inflatable structure. I have used explicit ALE method in a different software to achieve this, however it takes a long time to solve as the simulation time is 4 seconds. And I need to use a finer mesh but that would reduce my timestep and time to solve would be unrealistic.

I believe one solution is to switch to an implicit solver. Can comsol handle such a problem ? From my experience it needs to handle non-linear contacts, fluid - structure interaction and large deformations of the fabric.

Any info would be appreciated.

Thanks,
Shiva
