Praqsys develops, improves and maintains software tools for the aerospace industry. Praqsys has upgraded its Cequel product for use with Microsoft Excel 2010 & 2013. Cequel is an Excel Add-In function that allows the user to perform chemical equilibrium analyses as a spreadsheet function, based on the trusted NASA CEA Fortran code. Cequel solves the TP, SP, HP, TV, UV and SV gas properties problem, as well as the rocket, shock and detonation problems. Cequel takes the drudgery out of performing text based single calculations, and frees you to perform parametric analyses by just copying a function. Cequel provide both a spreadsheet function, and wizards to help you paste a new instance of the function into your spreadsheet. It lets you visually choose reactants from the CEA / TEP / PEP and Gun databases. Please visit www.praqsys.com for more information and to request a free 30 day Cequel trial, then set your spreadsheet on fire. (Cequel is a registered US trademark)
