I'm a novice at COMSOL and am struggling to achieve this simulation.

I'm attempting to essentially mimic the model of fluid flow past a sphere, but with air being released through "holes" along the edge of the sphere. Ultimately, I would like the sphere to be able to expand as a hyperelastic material as well. I haven't been able to achieve a successful model combining two separate fluid domains. Would greatly appreciate suggestions for what Multiphase Flow setup I should be using and any tricky COMSOL factors to consider!
