Simulates the effects of boundary conditions and lateral acoustic leakage in tubes by the axisymetric finite element method (axiFEM).
Predicts all the acoustic properties in the case of excitation by a plane wave of normal incidence such as: absorption coefficient, attenuation index, surface and characteristic impedance, number of complex wave, effective dynamic density and effective bulk modulus.
Takes into account:
The type of termination (air cavity, rigid bottom or anechoic),
The boundary conditions (embedded, sliding, with air leaks),
The type of skeleton (rigid, flexible and elastic),
The material thickness and diameter,
The atmospheric conditions,
The parameter uncertainties.
Retains materials identified by FOAM-X or your own method.
Searches for materials according to different criteria (e.g. price, porosity, resistivity to the passage of air, thickness, etc.)
