Hi All your queries can easily be dealt with fluent help.

1. For defining varying B.C. with time, you have to write an UDF.

2. while iteration, we can take contour pics at regular intervals of time through: solve--> monitors--> surface.

3. we can do animation files either by using animation option or by joining the contour pics at regular time intervals using some softwares that are freely downloadable from google.

with best wishes prasanth
