When designing a new equipment or existing equipment wants to be insulated surface temperature needs to be calculated for safety regulations. There are formulas to calculate this however they do not include thermal conductivity value over temperature changes. 

Simulation software gives accurate results for these calculations but not everyone has access to these software. Because of this reason we wanted to eliminate the need for simulations software and get a solution as close as possible to simulations with our own software and here is SuTSys. Since the software is in Beta version, we'd like to get your feedback both positive and negative.
