Using SpectraSim

{SpectraSim} takes a muffler CAD model through meshing, an OpenFOAM solution and a quality check, and reports the pressure drop. The acoustic solver gives the transmission loss and the insertion loss.

Theory

The path through the work

  • Physics: choose what to solve (flow, heat transfer, acoustics).
  • Geometry: load the CAD model, confirm the units and assign inlets, outlets and walls.
  • Settings steps: Model, Material, Boundary Conditions (with the absorptive backing), Solver Settings, Run Settings and Mesh.
  • Run: start the solution and follow the quality gates.
  • Results: review the results, generate the report and save the files.

Values that the program computes are marked auto. Typing in such a field makes it a user value; Reset to auto restores the computed value. Every step is saved when you leave it.
