Abstract(E)	Transmission Loss is a key metric for automotive components such as dash panels. While curved panel acoustics are well studied, panels with acoustic treatments receive less attention. Classical FEM and SEA methods are limited by cost and assumptions, and TMM applies mainly to homogenized geometries. Deterministic simulations combining FEM for structure, poroelastic modeling for treatments, and BEM for sound propagation offer greater accuracy. To extend frequency range and enable SEA integration, computation time must be reduced. This paper introduces a DMP-SMP parallel approach for FE-BEM-PEM workflows on trimmed dash panels and compares bare structures using an accelerated H-Matrix BEM solver.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
