Hello everyone!

I am running a transient simulation in a 3D model of the aorta bifurcating into coronary arteries. The model contains around 0.51 million elements. The chosen time step size is 0.001 sec and the total number of time steps is 1400. I am running it in a parallel processor. The number of iterations is 200 per time step. For this case, the solution is not getting converged. Whereas, when I simulate 0.5 million elements, the solution is getting converged for the same conditions. Can anyone suggest what modifications can be made?

Thank you!
