Hi everybody; after my first simulation I adapted one part of my geometry and replayed my simulation with that finer grid.My question is after this adaptation do I have to Initialize or not? and for example I want to write velocity values on another graph insted of writing on previous graph to compare the differences.What should I do? Thanks

You should not have to initialize. If you want to compare the velocity profiles, you could make an XY plot of the velocity values and write them to file. Then, when you have the new set of calculations, you can do another XY plot, and also read in the old XY plot that you saved. This will display the two profiles on the same graph.

Ok jeremy thanks for your reply. Bye
