Adam Powell's EBsurf Program

Greetings, and welcome to EBsurf. This is at its heart a 1-D heat transfer program, configured here to calculate the temperature fluctuations in a periodically-heated surface. The primary application to date has been electron beam melting and refining, and so the parameter definitions and stuff are all based on that.

Note: be sure you use the specified units! Otherwise your results will be meaningless. 

Case 1: "One-Shot"

This just runs the basic program at one prescribed average surface tempertaure.
