Mesh2HRTF_Project_Folder

The Mesh2HRTF project folder is generated upon Blender export (cf. Tutorials). The project folder contains all information needed to execute and adapt your HRTF simulation as well as do post-processing.

It consists of the following files:

• 3d Model.blend - A copy of the Blender file that was used to generate the project folder.
• parameters.json - Relevant user set parameters that are in part required for post-processing the NumCalc results.

and directories:

• Output2HRTF: This folder is generated by post-processing the NumCalc results and contains the final HRTFs and HRIRs in SOFA files, a project summary in text files, the sound pressure on the 3D mesh, and possibly files to visualize the sound pressure on the 3D mesh in ParaView.
• EvaluationGrids: contains the evaluation grids used for simulation.
• NumCalc: contains a sub-directories source_x for each sound source in the project.
  • source_x : containing the input file NC.inp for the NumCalc simulation as well as the simulated data once the simulation is run. This includes the file NC.out (a detailed log file of the simulation) as well as the sub-directories be.out:
    • be.out (see also Output File Structure): containins a folder be.x for each frequency bin x that was simulated with these files:
      • pBoundary and pEvalGrid containing the pressure and
      • vBoundary and vEvalGrid containing the velocity calculated on the boundary (head mesh defined in the ObjectMeshes folder) and evaluation grid (defined in the EvaluationGrids folder)
• ObjectMeshes - containing element lists and node locations of the geometry (e.g. head) mesh specified in Blender
• Pictures - if selected at export, contains shots from different angles of the geometry in Blender
