Custom

Quartus Engineering has developed custom software programs to address specialized analysis requirements.

Q-HYDRO

Q-HYDRO is a program for performing hydroelastic analysis of incompressible fluids in rigid or elastic tanks.

  • Completely enclosed
  • Free surface including slosh
  • Free surface with slosh mass removed

Q-HYDRO is based on the pressure formulation for representing an incompressible fluid. This approach has been shown to be very accurate for liquid propellant launch vehicles, satellite propellant tanks, and other applications.

Q-HYDRO develops input files to create fluid superelements using MSC.NASTRAN and is compatible with the structured solution sequences (SSS).

Q-DRM

Q-DRM is a suite of custom MSC.NASTRAN DMAP alters and related programs for creating data recovery matrices. This data is used for coupled loads analysis of complex systems such as launch vehicles and satellites. Q-DRM has the following features:

  • Craig-Bampton stiffness and mass matrices
  • Data recovery matrices for accelerations, displacements, element forces, stresses, and interface loads
  • Mode acceleration method for accurate displacements and loads
  • Compatible with both single level and multi-level superelements

Quartus uses these programs to perform specialty projects. We also sell the programs to our clients. Deliverables include source code, documentation, and example files. On-site training and extended support can also be provided. Please contact us for more information on any of the custom programs or support services.

Q-Dynamics

Q-Dynamics is a time and frequency based dynamics analysis toolkit for use in structural dynamics data processing. When coupled with our extensive FEA and testing capabilities this toolbox helps Quartus to quickly understand, compare, and correlate test and simulation responses.

  • Vibration testing and correlation
  • Optical performance tests
  • Various aircraft and spacecraft modal and life performance tests
  • Consumer product qualification and environmental tests

Q-STOP

Q-STOP is a custom optical performance toolkit developed by Quartus for performing Structural-Thermal-Optical-Performance (STOP) analysis of optical components and systems.  It works with ZEMAX, NASTRAN, and Abaqus inputs and outputs to perform the following tasks:

  • Surface figure error analysis
    • Zernike polynomial fitting, residual surface figure error calculation, distortion shape recovery
  • Stress birefringence analysis
  • Thermo-optic analysis
  • Automatic generation of optical performance MPCs (via FEMAP API)
    • Frequency & phase-consistent tracking of pointing/boresight

Q-STOP allows Quartus engineers to quickly assess the optical performance of complex optical systems for a variety of mechanical environments.

CUSTOM FEMAP APIs

Quartus has developed a library of hundreds of custom FEMAP APIs (Application Program Interface) to add functionality, automate tasks, and efficiently couple commercial codes (FEMAP, NASTRAN, Matlab, Excel, ZEMAX).  Examples of custom APIs include:

  • Dynamics toolkit
    • Integrates dozens of custom tools for creating and post-processing NASTRAN structural dynamics analyses
  • Temperature and pressure mapping
  • Meshing and model modification tools
  • Composites toolkit
  • Fatigue & fracture toolkit
  • Post-processing toolkit

Quartus engineers are experts at generating custom APIs to meet internal or customer needs.
