Impose a limitation for solving an equation

Hi,
I'm using general PDE in COMSOL. I want to solve the equation by this condition:
The calculated main variable in each time step can not decrease, in other words if A is the main variable, then dA/dt>0 (t is time) .

How can I impose this condition?

Thanks,
Arezoo
