"If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts, he shall end in certainties."
-Sir Francis Bacon
The beginning of a new year is a good time to clean up many bits and pieces of various descriptions. In this Newsletter, we do just that. For example, in a postulated nuclear reactor accident involving a broken pipe, the outrush of high-pressure water may damage surrounding structures creating bits and pieces of insulation or other debris. Of concern is the possible transport of this debris to pump inlets where it might hinder their ability to circulate cooling water. In the Application Note, a group of users describes how they have used FLOW-3D to investigate the flow of water and debris under hypothetical accident conditions.
In Hints & Tips, you will find some excellent suggestions for cleaning up unnecessary bits in video files to reduce their size, in some cases by orders of magnitude.
And, finally, the Development Focus describes how best to break up computational grids into pieces for the most efficient assignment of work to multiple processors in a distributed memory, parallel computing network. Dealing with bits and pieces can be satisfying when they are brought under control. It is hoped that you find as much satisfaction as we have from the articles in this issue of the Newsletter.
