comsol ode+application modes

I need to model pressure acoustic with this differential equation:
a*r*rtt+1.5*r*(rt)^2=p0 a=density of fluid, p0=pressure distribution resulted from solving of pressure acoustic in the domain
1- How can I solve this problem? In "Global equation” I couldn’t insert the results from other application modes.
2- I also try to solve my problem in PDE, General, Time dependent analysis (combined with my first acoustic application mode)
?=0,0 F=p ( resulted from acoustic pressure) ea=1000 da=1500
in boundary condition (R=-r which means that in all the boundaries r=0)
I need comsol to solve my acoustic pressure then use this pressure distribution and then solve my PDE. How can i manage this? I solve pressure acoustic with time harmonic (choose in "solve for” tab (in "solver manager" ) just p ) and then choose "time dependent solver" and then in "solve for" choose "pde" but i couldn't get my results.
Can I use two different solvers (like what I choose, time harmonic and time dependent) in one model with two application modes?
Any answers would be greatly appreciated
