• GRADELA — simple gradient elasticity model
• Matrix splitting — general method of splitting a matrix operator into a sum or difference of matrices
• Paul Tseng — resolved question on convergence of matrix splitting algorithms
• PISO algorithm — pressure-velocity calculation for Navier-Stokes equations
• Projection method (fluid dynamics) — computational fluid dynamics method
• Reactive transport modeling in porous media — modeling of chemical reactions and fluid flow through the Earth's crust
• Richard S. Varga — developed matrix splitting
• Strang splitting — specific numerical method for solving differential equations using operator splitting
