how do i avoid error resulting from inconsistent initial variable deci12

i am solving a DAE equation M=[1,1,1,0,0,0,0] with Reltol =1.0e-3, using the loop and after 55days i got an error which says my initial condition is not consistent deci12. the solver for the simulation is ode15s.

for Day = 1:365 for hour = 1:24

        [tout,Tout]=ode15s(@sysode,t,init,options,MATERIAL,ELEMENT,Day,hour,V,z,theta,S_1,S_2,S_3,S_5,VF, T_amb_Ka, T_amb_C); %calling ode15s for solution
        init = Tout(length(Tout),:);
        Hour = ((Day-1)*24)+hour;
        Tsol(Hour, :) = Tout(length(Tout),:);
%         [Hour init];
%         Tout;
%         tout;

    end
    Day
end

thanks
