You can get point values during the run by use of the VAL(<expression>, <x-coordinate>, <y-coordinate>). You can use this in REPORTS or in SUMMARY pages. You can also plot histories of the values at various pre-selected points in the domain. ELEVATION plots along selected lines or boundaries make it easier to read off numbers.
