I tried with turning off the all you suggested. After giving the boundary conditions, I checked in the check case under run calculations. There are no recommendations under mesh. Under solver, there is a recommendation to change the method from first order upwind to second order upwind. Nothing else has come up. Still the Segmentation error is coming. Anything else you would suggest where I can check?

Also in student version 2019R2, the error is, f1 process cannot be started.
