AFT 30 Years Ago and Today

September 14. That is the day I consider to be AFT's official birthday. In 1993 I resigned from my job in the power industry and started working on AFT Fathom 1.0 full-time that day.

Perhaps it will save you some time as well in the design phase. As engineers, we like details and will enter as many as possible into our models.
