Model checks in Space Systems Thermal

This article outlines methods to verify that a model functions as expected, covering fundamental Space Systems Thermal model checks.

Details

Model checks are a set of verification processes used to ensure the accuracy, quality, and reliability of a simulation model. You will learn:

  • Reasons for conducting model checks.
  • Common issues and suggestions for units, expressions, materials, thickness, and mesh density.
  • Evaluating element quality and orientation.
  • Identifying coincident and duplicate nodes.
  • Conducting geometry checks.
  • Assessing mass properties.
  • Inspecting optical properties.
  • Verifying thermal couplings.
  • Checking radiation enclosures.
  • Verifying multi-layer insulation.
  • Checking orbits.
  • Checking solid motion effects.
  • Resolving ID conflicts.
  • Reviewing model setup and log files.
  • Configuring solution settings, integration time steps in the presence of an orbit, and automatic time step calculation.
  • Resolving warnings.
  • Analyzing results.
  • Best practices.
  • Using a thermal coupling report tool.
  • Using the TMG Correlation tool for model-to-test/analysis data correlation.
