Solving air-cups inner pressure and its inner air leakage with giving heavy weight in time dependent

Hello everyone
I want to solving air-cups inner pressure and its inner air leakage with giving heavy weight in time dependent
But i don't how to set air leakage with giving heavy weight on air-cups!!
For now, i can solve air-cups inner pressure with giving heavy weight in steady state , so i want to know the result if my air-cups leakage just like in my real case.
And i want it to leak with time , so i use time dependent to simulate it, but time has failed to converge.

PS. My model refer to 〝Hyperelastic Seal〞in COMSOL model example!

Thanks everyone help!!
