thank you for the reply. nPreviously I was generating velocity contour images and autosaving transient data when the simulation was progressing. I changed all that in a new simulation with nothing but just simulation displaying Monitoring parameter's graphs. The actual time taken was close to 480 seconds for 5000 iterations but the Wall Clock time still shows 17.807 secs. nRAM and CPU Usage; CPU usage shoots up from 5% to 89% but the RAM usage doesn't really change as much (5.8 % to 5.9 %) during the simulation. I will attach screen shots.n Ie single chip or dispersed cluster: I don't exactly understand what these are and how to find it. But this Ansys License is installed in a single computer (standalone) and isn't connected to the network for simultaneous use. If this helps.nn
