Fluid Materials

Definition

Fluid material with losses.

Description

General
COMP' Bulk Modulus Pa or N/m2
  Density kg/m3
Losses
COMP" Imaginary part of the Bulk Modulus
Must verify COMP" ≥ 0
Magnetic
Relative magnetic permeability
Superpose magnetic domain to elastic domain

Illustration

ATILA Implementation

- Interface elements (between solid and fluid regions of the model) are automatically added by the ATILA-GiD interface.
 
- The orientation of interface and radiating elements is assigned by the ATILA-GiD interface, independently from the orientation of the elements within GiD.
 
- When the magnetic permeability is enabled, the mesh is "duplicated" so that a magnetic field computations can be performed on top of the elastic domain. Thus, both domains share the same nodes. This feature is typically used in magnetostrictive problems.
