In a series of articles [1,2,3] we have developed a method for optimal design of gas turbine parts using topology optimization together with the finite element method for structural, thermal and flow analysis. Recently, PhD student Jonas Lundgren, for whom the PI is main supervisor, was granted a project, LiU-compute-2022-30, at Sigma with 20000 core hours per month. However, since even a single optimization run on a medium-sized, academic 3D problem requires around 5000 core hours, I decided to apply for a Medium project to support our joint work on this in order to be able to treat problems sizes relevant for industrial applications. Previously Jonas has been able to use time from my project SNIC 2022/5-134. However, that project is mainly used for other research activities (such as development of a novel Darcy flow model including explicit length-scale control, robust topology optimization with models of the AM build process and optimization of composite structures under uncertainty) which are expected to take up even more of the allocated time onwards. The usage in that project was already high before summer, and given what we have in mind for the future, described more in detail in the project LiU-compute-2022-30, we believe that we cannot incorporate this under the existing resource allocation.
