Unsteady Analysis

I am solving a unsteady state problem, in which i need to solve two unsteady equations. The solution of first unsteady state equation, which depends on time, is used in solving the second unsteady state equation. I solved first unsteady state equation separately, it is converging. But I tried to solve the second unsteady state equation by keeping these two unsteady state equation under single study step.(Study->Step:Time dependent). The equations are diverging. Can these two unsteady equations solved under different study steps in the same study sequence i.e.,(Study-> Step1:Time dependent, Step2: Time dependent). Because this means that the comsol remembers the time variation of the first steady state eqaution, then only the second steady state equation can be solved separately without simultaneously solving them. I actually doubt whether comsol remembers the time variation also? Please someone help me regarding this.
Thanks in advance
