Thermo-Elastohydrodynamic
Simulation (TEHD)
The TEHD feature in FIRST takes into account all material-specific properties of the bodies present in the simulation such as specific thermal distortion, heat capacity and heat transition coefficients as well as all temperature-dependant parameters of the lubricating medium and combines them with the EHD simulation.
