ANSYS FEA and CFD engineering analysis software have been widely used in all types of building construction projects.  ANSYS can be used in assisting engineers benchmark designs using the LEED Green Building Rating System.  Airflow modeling (CFD) can assist in the process of developing and evaluating design concepts as well as contributes to the evidence that a proposed design meets various rating criteria

The SimuTech Group technical staff provided engineering expertise on the following projects

  • Building wind loads under hurricane-strength winds from CFD analysis
  • Structural model of large underground nuclear waste tanks with rebar-reinforced concrete and nonlinear frictional soil model With custom GUI. Rebar-reinforced utilizing Drucker-Prager material models
  • CFD wind study for high rise building development to verify proposed design maintains local velocities to defined industry limits
  • Water treatment plant comparative CFD tracer study to predict water residence times to ensure optimum contaminant oxidation
  • Water storage standpipe facility CFD study to determine liquid mixing/cycling performance
  • Explicit dynamic study of 100 year old dam response to adjacent bedrock blasting
