Product Logo

shonTA is a thermal analysis software based on the thermal network method and the FEM method. It is the perfect solution for 1D and 3D transient modeling of electric drive systems. It can simulate for example the three-dimensional temperature distribution of windings or other parts of E-motors and give insights on the system’s situation when thermal balance has been reached. ShonTA can simulate the heat losses, contact heat transfer, heat conduction and heat sink in transmission systems and in E-motors. Additionally, it can be coupled with shonDy (particle based fluid simulation) and shonFlow. With shonDy oil splashing analysis in E-motors can be conducted to get heat transfer coefficients. Coupling shonTA and shonDy provides a new simulation tool and method for E-motors and electric vehicles. Together with shonDy fast 1D conjugate heat transfer (CHT) analysis can be done.
