This industrial paper introduces the new Liquid Cooling Library (LCL) that is available in ANSYS Twin Builder Heating and Cooling Library bundle. This library is a multi-tool compatible Modelica Library which can help customers to deploy simulation of cooling systems in a new way. In general, LCL can be used for modeling cooling circuits across many industries like aerospace, automotive and process industry. The combination with the extensive electronics and electrical machine libraries in Twin Builder makes LCL a natural fit for cooling of power electronics and thermal management of electric vehicles.

A Modelica library for the simulation of well construction (drilling) is presented in this paper. The library contains most of the components of a drilling system. The simulation model is capable to capture the main dynamics of the well, including the hydraulics, the mud transport, the mechanics of the drill string as well as the drill bit interaction with the bore hole. The library is well suited to simulate the well operation and to support the development of new technologies. The modelling assumptions of the library's components are first reviewed. Subsequently, an experiment is performed to test the rotational and translational frictions.
