Recent advancements in additive manufacturing have facilitated the production of conformal cooling channels with greater ease and cost-effectiveness. Compared to typical channels that are straight-drilled, conformal cooling channels (CCCs) provide enhanced cooling efficacy in the context of the injection molding process. The main rationale behind this is that conformal cooling channels (CCCs) possess the ability to conform to the shape of a molded object, which is not possible with conventional channels. Carbon-carbon composites (CCCs) have the potential to mitigate thermal stresses and warpage, decrease cycle times, and achieve a more homogeneous temperature distribution. Traditional channels utilize a design technique that is more intricate in comparison to CCC. The utilization of computer-aided engineering (CAE) simulations is crucial in the development of a design that is both efficient and cost-effective. The primary objective of this paper is to assess the efficacy of two ANSYS modules in order to validate the obtained results. The two modules demonstrate similar outcomes when used with models with a fine mesh. Hence, it is crucial to take into account the purpose of the study and the intricacy of the computer-aided design (CAD) geometry in order to make an informed choice regarding the appropriate ANSYS module to utilize.
