Tension Software has updated TS Calc (http://www.pomola.com/products_tscalc/tscalc.html), a Mac OS X app for solving mathematical models applied to technical problems of various types, to version 1.1.3. It’s a maintenance release that fixes some bugs.

TS Calc is a document based application and its documents can be realized and used as calculation models for a specific mathematical technical problems. These documents can also be distributed as pre-made solutions for various type of technical problems with all the requested equations inside and all the variables pre-inserted with acceptable range already set.

A TS Calc document contains a series of equations and a list of variables and constants used by the equations. The user can insert different input and see the output generated by the TS Calc document using the equations solving the problem.

TS Calc includes a calculation engine entirely developed and coded internally by Tension Software in C and Objective-C, able to solve equations with any nested level of parenthesis, variables and a large type of mathematical functions.

TS Calc is Universal Binary so runs natively on both PowerPC and Intel Macs. It requires Mac OS X 10.5 or higher. TS Calc costs US$30, though version 1.1.3 is a free update for registered users.
