Applications of Finite Element Method (FEM) in High-Temperature High-Pressure Experiments

I have been applying the Finite Element Method (FEM) to high-temperature and high-pressure experiments since 2007. FEM is a tool for numerically solving phenomena described in partial differential equations. FEM divides an object into meshes (finite elements), which enables us to handle complex geometry easily. I have been conducting FEM by using COMSOL commercial software, and was invited to give a talk at the COMSOL conference in 2019. At the conference, I presented the FEM applications which I have conducted. Based on the opportunity, I summarize the contents of the presentation in this document.
