Important Notice To My Colleagues

Cats2D was solely written by Andrew Yeckel and Ralph Goodwin and it belongs exclusively to us. The research group of Jeffrey Derby at the University of Minnesota is no longer allowed to use it. Derby and the university defied my legally enforceable cease and desist letter for seventeen months, forcing me to sue for its control.

Derby has also plagiarized my work in several research areas, including the traveling heater method, the particle engulfment problem, and the temperature gradient zone melting method. I have filed complaints with the University of Minnesota about this plagiarism and have submitted to them extensive proof of my pivotal contributions to the works in question. The pace of their inquiry is glacial, going on for fifteen months now without any sign of meaningful progress. Some of these published works have been in circulation for over two years now.

This situation has been extraordinarily damaging to me. I urge my colleagues to view the evidence themselves, and to form their own judgements. I deserve credit for my academic scholarship. And please visit the links to my web site found below, especially the page on recent developments where I frequently add new content. Cats2D is a marvelous and powerful tool. I would like to see it used more widely in crystal growth research. -- Andrew Yeckel, 31 March 2019
