How to display contour of different time step.
 
Maybe, this is a very stupid question. How to display or plot the contours at different time step for a unsteady state problem? Now I only can display the last step result.

Your quick answer is really appreciated.

Under Solve -> Execute commands you can enter commands that are executed every timestep. So, for example, you can enter 3 commands as follows for a static pressure contour with range 10000 - 20000 on a plane called 'middle', and then generate a hardcopy:

/display/set/contours/surfaces middle ()

/display/contour pressure 10000 20000

/display/hard-copy "pres_%t.jpg"

The jpeg file will have the timestep included in the filename.

One more flaxible method is use FILE-->WRITE-->AUTOSAVE..., then you can save the case and data files every time step (or every several time steps). After the calculation, you may open them seperately to do some post processing. BTW, make sure you have enough disk space to save these *.cas & *.dat files.

Thank you very much. This is a good and simple method.
