Actran Training – ACOUSTICS

ACOUSTICS_1_General_Program_Organization

Actran is a complete acoustics, vibro-acoustics and aero-acoustics
simulation softwareActran is based on the finite and infinite element methodActran provides a rich library of elements, materials, boundary
conditions, solution schemes and solve

  • PRE-REQUISITES – beforegoing through this presentation, the reader should have read and understood the presentation Actran General Organization
  • These slides present the ACOUSTICs MATERIALS, COMPONENTS and BOUNDARY CONDITIONS involved in a pure acoustic simulation.

• PRE-REQUISITES – before going through this presentation, the reader should have read and understood the presentations:

  • Actran GeneralOrganization
  • Actran Acoustics Simulations -General

ACOUSTICS_2b_Acoustics_simulations

• These slides present alternative methods for the study of the acoustic propagation in far field:

  • The PMLcomponent,
  • The APMLcomponent,
  • And the EXTERIOR_ACOUSTIC

ACOUSTICS_3_Damping_Acoustics_simulations

PRE-REQUISITES – before going through this presentation, the
reader should have read and understood the following
presentations:
– Actran General Organization
– Theory Actran Acoustic Simulation
These slides present the different MATERIALS, COMPONENTS and
BOUNDARY CONDITIONS that can be used to include damping in
acoustic simulations

ACOUSTICS_4_BC_MESH

This presentation details the different features of ACTRAN to
efficiently model pure acoustic radiation problems
The following topics are reviewed
– Acoustic Radiation Procedure (BC Mesh)
– Solving methods (Direct Frequency Response, Green Analysis)

ACOUSTICS_4b_RADACT

PRE-REQUISITES – before going through this presentation, the
reader should have read and understood the following
presentations:
– Acoustic 4 BC MESH for Acoustic Radiation Problems
These slides present the usage and advanced post-processing
features of the RADACT utility used for automated acoustic
radiation

ACOUSTICS_5_Duct_modes

PRE-REQUISITES – before going through this presentation, the
reader should have read and understood the following
presentations:
– Actran General Organization
– Theory Actran Acoustic Simulation
These slides present the coupling of an acoustic finite element
model with ACOUSTIC DUCT MODES
In DUCT ACOUSTICS, the acoustic duct modes can be used to
represent an IMPOSED INCIDENT ACOUSTIC WAVE (engine pulse,
turbo-fan noise) and/or to represent an acoustic anechoic
termination, that is a semi-infinite duct
The present document focuses on ducted systems

PRE-REQUISITES – before going through this presentation, the
reader should have read and understood the following
presentations:
– ACTRAN General Organization;
– Theory ACTRAN Acoustics;
– Theory Damping in Acoustic Simulation
These slides present the visco-thermal fluid COMPONENT in Direct
Frequency Response and Modal Frequency Response

– Theory ACTRAN Acoustic Simulation
– Workshop 1 – Radiation of a Horn Speaker
These slides present the process for projecting CFD mean
aerodynamic results in order to account for their effect on an
acoustic analysis with Actran
The Actran iCFD module is used for that purpose

ACOUSTICS_8_Theory_Field_User Function
