Contributions summary:Cheng primarily contributed to the Elmer FEM software's time integration methods and predictor-corrector schemes. Their work involved implementing and refining time-stepping algorithms like Adams-Bashforth and Adams-Moulton. They introduced an adaptive time-stepping controller, which included local truncation error estimation and PI control. These changes suggest a focus on improving the solver's numerical methods and time integration capabilities within the finite element framework.
