an-esim: "pronouced as any sim" is the diagram mechanization tool. an-esim authors simulations of electrical, mechanical, pneumatic and hydraulic diagrams. It utilizes a easy to use interface to quickly produce functional simulations. an-esim capitalizes on the Atlas production tools by allowing users to select functional circuits from the CGM diagrams and dropping them into an-esim. Once the circuit is in an-esim an instructor, student or troubleshooter can mechanize a simulation in minutes. Once a diagram has been authored in an-esim it can be used from within a web browser..
