FEM Multiphysics:
Solid Mechanics:
- Modelling: Can model a wide range of structures, contacts, and nonlinearities, including
hyperelasticity, elastoplasticity, viscoplasticity, creep, porous plasticity, and shape memory alloys.

frequency analysis, and buckling analysis for structural stability.
- Composite Materials: Expertise in modelling composite materials, including micromechanical
analysis and delamination modelling.
- Fatigue Analysis: Can analyse high-cycle and low-cycle fatigue, including cumulative damage,
energy-based fatigue, thermal fatigue, vibration fatigue, and stress- and strain-based critical plane

- Multibody Dynamics: Proficient in modelling and analysing systems of interconnected rigid and
flexible bodies, vital for designing moving mechanical systems.
Acoustics
- Analysis Methods: Proficient in analyzing vibro and aero acoustic responses, both in the
frequency domain using the Helmholtz equation and in the time domain using the scalar wave equation.
- Sound Propagation: Efficient modeling of sound propagation in solids and fluids, allowing for the
study of acoustic behavior in different media.
- Specialized Acoustic Models: Capable of modeling thermoviscous acoustics (considering thermal and
viscous effects), ultrasound (high-frequency sound waves used in medical imaging and industry), and ray
acoustics (focused on ray tracing and sound propagation).
- Boundary Conditions: Utilizes perfectly matched layers (PML) to effectively simulate wave
absorption at boundaries and infinite domain modeling for scenarios where wave propagation extends
indefinitely.
Computational Fluid Dynamics (CFD)
- Fluid Flow Simulation: Proficient in modeling fluid flow by considering the fundamental
principles of conservation of momentum, mass, and energy in fluids for compressible and incompressible
flows.
- Turbulence Modeling: Capable of using Reynolds-averaged Navier-Stokes (RANS) turbulence models
and Large Eddy Simulation (LES) for accurately simulating turbulent flow phenomena.
- Specialized Flows: Expertise in modeling specialized flow scenarios such as thin film flow (very
thin layers of fluid), multiphase flow (interactions between different fluid phases), porous media flow
(flow through porous materials), high Mach number flow (high-speed flow), non-isothermal flow
(temperature-dependent flow), and fluid-structure interaction (interaction between fluids and structures).
Heat Transfer
- Heat Transfer: Proficient in modeling heat transfer through conduction, convection, and
radiation.
- Conjugate Heat Transfer: Capable of simulating conjugate heat transfer, considering interactions
between fluid flow and temperature distribution.
- Non-Isothermal Flow: Expertise in modeling non-isothermal flow effects, where temperature
variations significantly affect fluid behavior.
- Radiation Modeling: Can model surface-to-surface radiation interactions, including those on
diffuse surfaces, mixed diffuse-specular surfaces, and semi-transparent layers.
Manufacturing and CAM
- Manufacturing Process Modeling: Proficient in modeling various manufacturing processes, including
welding, forming (sheet metal and bulk metal), additive manufacturing, and Computer-Aided Manufacturing
(CAM).
- Distortion & Stress Analysis: Capable of predicting and analyzing profile distortions, residual
stresses, temperatures, and heat-affected zones in manufactured components.
- Microstructure Simulation: Expertise in simulating the development of microstructures during
manufacturing processes.
- CAM & CNC Simulation: CAM plays a critical role in CNC machining, where it simulates the toolpath
and generates precise instructions for CNC machines to follow during the manufacturing process.
Dynamic System Simulation
- Multiphysics Systems: Many modern systems, such as automobiles, are multiphysics in nature,
involving multiple physical domains such as mechanical, electrical, controls, green energy, hydraulics,
pneumatics, thermics, and power transmission. Understanding and modeling these systems holistically is
crucial for effective design, analysis, and optimization.
- Subsystem Modeling: Within multiphysics systems, subsystems represent distinct functional areas
like mechanical, electrical, and hydraulic systems. Since these subsystems interact with each other,
modeling them together is essential to understand their combined behavior.
- Component-Level Modeling: Each subsystem consists of components such as engines, motors,
batteries, compressors, tires, valves, and functional units. These can be represented using
lumped-parameter models that simplify complex physical systems into manageable mathematical
representations based on engineering parameters. These models simplify complex physical systems into manageable mathematical representations.
- Efficient Simulations: This mesh-free modeling approach avoids the need for detailed meshing,
which can be computationally expensive. By applying suitable assumptions and simplifications, engineers
can derive ODEs that govern system dynamics, enabling fast and efficient simulations on standard
computers.
