Hi I have to find out maximum pressure in a domain and this is to be used to calculate density in a particular region alone. Anybody can suggest me to how can i select particular region in a domain and to find max pressure in domain. Thanks in advance.

Display-Contours-Compute. This will give the max. and min. pressure values in the domain. After then deselect auto range and define range giving the min. value nearer to the max. value. Then click display.
