When it comes to day-to-day vibro-acoustics engineering, our customers exactly
know what they want. They want to have the fastest solvers
the most efficient processes and for most a 100% accuracy
and this is exactly what
LMS Virtual.Lab Acoustics revision 12 brings to the table
for a variety of new exciting applications
So let me highlight a few of these applications starting with the analysis
capabilities for sound treatment
So sound treatments are today used all over the place. It is very important of course to
reduce noise
but also it's important to make sure that
material costs and manufacturing costs are reduced as well
and that calls for simulation, lots of simulation
and in revision 12 context, we are now offering a very scalable
fit for purpose solutions starting with very standard, very rapid
equivalent fluids models typically for modeling light fibers
up to the very sophisticated full
3D poro-elastic material capabilities implementing the BIOT
algorithms
When it comes to noise
fans can be a tricky source to analyze if you're talking about fans like cooling
fans and
ventilators and blowers typically this all noise spectrum has 2 components
it has the tonal component
and it has the broadband component
In the past number of years we have been successfully dealing with the tonal
component of that noise
now in the revision 12 context, we are hearing accuracy fidelity to the total noise
spectrum of fans by adding that broadband component with some unique
capabilities in this regard
So when you do fans design,
fans blades design, fan installation, you can really take the guess work out of
the acoustic analysis
At LMS, we always have been very known and appreciated by our customers
for our solvers, solvers performance
and this is why I am very pleased to introduce a trend setting breakthrough
new solver FEMAO
So this new solver already today sets new standards for acoustic performance
we have reported
gains in CPU time over a factor of
54 industrial cases
So how does it work? Well as a user you generally create your acoustic
Finite Element mesh
as a standard Finite Element solver
but in this case this acoustic mesh can be very course you don't care about six
elements per wavelength or high-frequency. Create a very course
Finite Element mesh
and it's the solver itself that will make sure that the course Finite Element mesh
is taken up too high frequencies
by using adaptive ordered algorithms when it increases the frequency range
a truly must-have solver in the years to come
when you're serious in acoustics simulation
Finally, Siemens NX NASTRAN
the outstanding structural Finite Element solver
perfectly complements Virtual.Lab Acoustics delivering a full vibro acoustic
solution
