Computational Sciences and Engineering Research Group

We are seven dedicated permanent reserachers together with several PhDs and postdocs with a vision "Mathematics for a better society" and an ultimate mission to "bridge the gap between high fidelity numerical simulations and real-world applications". To this end, we aim to be a market leader in providing comprehensive, validated and cost-effective solutions in following broad areas:

Numerical Modeling

• Discretization: Finite elements (FEM), finite volumes (FVM), Discrete Element models (DEM) and isogeometric analysis.
• Adaptive refinement methods using error estimation and local refinement.
• High performance computing (HPC): Iterative methods and parallel algorithms for solving large-scale systems in a reasonable timeframe.

Physical Modeling

Much of our work in physical modeling revolves around fluid and solid mechanics, as well as coupled problems. - Fluid mechanics: Computational fluid dynamics (CFD), multiphase flows, multiscale problems, turbulence modeling and microfluidics.

• Solid mechanics: Thin wall structures, nonlinear elasticity and dynamic problems.
• Coupled problems: Poroelasticity, Thermoelasticity, fluid-structure
  interaction (FSI) and fracture propagation.

Engineering models

• Parameterization: Homogenization
• Reduced Order Modelling: Based on POD, SVD, Real time simulators
• Dimensional reduction: Strip theory, BEM
