WebApr 12, 2024 · I have an issue in my code i.e.,"TIME LOOP NOT WORKING PROPERLY". I'm dealing with unsteady case. For that unsteady case the equation has dt (time step). in addition, I'm using COLD for previous time level(C^k) and CNEW for new time step level(C^k+1). here how can i include time level in my equation and reach steady state?
