Over its 40+ years of operation, the staff of Continuum Dynamics, Inc. have developed a broad base of experience that allows us to address a wide range of challenging problems for our customers. A selection of our recent and ongoing work includes:

  • unique, high fidelity analysis, design support, and simulation tools for aircraft, rotorcraft, eVTOL vehicles, and wind turbines;
  • novel hybrid CFD methods offering high modeling fidelity in realistic aerodynamic and hydrodynamic problems with greatly reduced setup and computational cost;
  • state of the art acoustic and fluid/structural interaction modeling for power plant piping systems; 
  • advanced computational algorithms for molecular dynamics modeling as well as a wide range of High Performance Computing (HPC) problems;
  • efficient, physics-based modeling of stores separation, countermeasures dispersal, and groundfall of aerially released materials;
  • compact smart materials-based devices for multiple applications, ranging from rotorcraft vibration mitigation to intelligent flow control for wind turbines;
  • scaling methodologies and deep test support experience enabling high payoff, fast-turnaround assembly of critical engineering data

The following summarizes a partial list of particular areas of past and ongoing work.
