To realize the potential of web-based interactive design tools, Ferraz Shawmut (formerly R-Theta Thermal Solutions) introduced R-Tools® some years ago as a free online thermal modeling tool for heatsinks. This year, Ferraz Shawmut is introducing a new version of R-Tools which is based on an advanced three-dimensional numerical model.
