The focus of this paper is on the modeling of an existing machine frame with its cooling structures. An overview is given of all the modeling methods used, their respective sub-targets and their interactions with each other. The modeling workflow encompasses both the mechanical and fluidic properties of the machine frame, including the fluid circuits and their control. The study results are the different requirements for modeling and the achievable result accuracy with regard to the temperature and deformation field. It forms the basis for the subsequent investigation of various temperature control variants, which are not part of this paper.
