During my graduate studies, I conducted research on plasma magnetohydrodynamics (MHD) through numerical simulations. I independently developed a numerical simulation program, beginning with the selection of governing equations tailored to the target phenomena, followed by their discretization and implementation into the program. The results obtained from these simulations were presented at academic conferences in Japan. I am proficient in utilizing finite difference and finite volume methods (FDM and FVM) for discretization and can effectively work with generalized coordinate transformations to accommodate non-orthogonal and non-uniform grids. The simulation program was developed in Fortran 90 and compiled using gfortran. Currently, I am studying the finite element method (FEM) and expect to become proficient in its application soon. For solving linear systems of equations, I employed the CSR format for storing coefficient matrices and used the LIS (Library of Iterative Solvers) linear solver library to obtain solutions. I am also skilled in working with composite meshes. For visualization of numerical results, I utilized ParaView as well as Python scripts that I personally developed, demonstrating my proficiency in Python programming. I am adept at employing a semi-implicit method for solving Poisson's equation, a 4th-order Compact MUSCL TVD scheme for advection terms, and the gradient theorem for diffusion terms. For temporal evolution, I can implement a 4th-order TVD Runge-Kutta scheme.
