• I also want to express my sincere gratitude for developing this wonderful software.
• I have to say, this software is amazing for the R&D engineering work that I do. Being able to whip up simple (or complicated) 1D models, have access to the breadth of material properties, run fitting routines for curve fitting and model fitting to data, has enabled us to quickly optimize experiments and turn around results. This has become my new secret weapon in my R&D team. I appreciate that this is still supported and continues to improve with each update.
• I'm working with EES's "Introduction to Statics" in conjunction with the book "Statics" by Costanzo, Craig, and Plescha. Excellent.
• We find this tool (EESyGrader) extremely useful.
• We are using EES Professional extensively in our research on two-phase liquid cooling with refrigerants. It's a godsend.
• MathCAD & Refprop can't compare to f chart EES.
