Noise and Vibrations

Brake Squeal Analysis: Brake Squeal Analysis is supported by two step process. One starts with nonlinear static solution to obtain the static equilibrium of brake assembly. Then, the complex eigenvalue analysis to follow. It must be ensured during the nonlinear static solution that the contact between the disc and the pads is in the dynamic friction status when converged.

•	RANDOM case control supports SET ID that points to RANDPS bulk IDs: RANDOM case control is enhanced to point to SET which in turn lists the id of RANDPS bulk IDs.

•	RBODY enhancement: RBADD can now reference another RBADD. Also, no case control RBODY is required anymore and in that case, all the RBADD/RBODY in bulk data will be used for analysis.

•	Fluid Mass/Volume output in .out file: Mass/Volume for Fluid in Acoustic Analysis is available in .out file.

•	Composite Stress and Strain as PLY results: Available in .op2 file for Frequency Response Analysis.

•	NSGE on Fluids: Non Structural Material Damping via NSGE is now supported for fluid elements.
