Ultrasonic Modeling

I'm interested in information on ultrasonic modeling (simulation) programs for use in technique development and signal interpretation of structures with complex geometries that are accesible from only one side.

It seems that there is increasing mention of models and simulations circulating throughout various discussion groups and its quite obvious to me the benefits of these programs to certain applications.

I'm curious as to how reliable and useful these programs could be and whether there are currently any available for purchase for indivudual use?

Thanks
Doug Mendes

Re: Ultrasonic Modeling
I have not used this software, but it looks good. The folks at UTEX are quite helpful.

Re: Ultrasonic Modeling
Wave2000 is another package that can do 2D modeling.
See the following URL for examples: http://www.cyberlogic.com

Re: Ultrasonic Modeling
Imagine3D is a ray tracing program, and as such, does
not model all of the interactions associated with
ultrasonic propagation. It works pretty well in blocks
of homogeneous media (like layered media), but not so well
with flaws and model structures anywhere on the order
or several times the order of a wavelength. On the
other hand, Wave2000 models all the interactions
of ultrasound with a structure. This comes at a price,
however, the price of increased computational
overhead. But flaws and an ultrasound wavefront
interaction with it are computed without any signficant
error.

Please note: My company (Cyberlogic, Inc.) produces
and sells Wave2000.

Dear Mr. Mendes,

a collegue from the university of Linz, Austria, forwarded me your inquiry on
ultrasonic modeling tools. We have developed the
finite-element-boundary-element simulation program CAPA, which is dedicated
to the modeling of electromechanical transducers (incl. piezoelectric,
magneto-mechanical and electrostatic), acoustic wave propagation in media at
rest and in flow (incl. nonlinear acoustic waves). This program is in use at
several industrial companies and universities, worldwide, allthough primarily
based in Europe. As far as I can see from your inquiry, these problems can be
simulated with our program very efficiently.
For a first information on CAPA, you may have a look at the web-page of the
institute of Prof. Lerch at the university of Erlangen. Just point your
browser to the following address:
http://www.lse.uni-erlangen.de/CAPA/index.htm.
We have also produced a CD providing an overview over the software system.
Furthermore, the slides of the shortcourse 'Computer modeling of
electromechanical transducers' held by Lerch, Kaltenbacher, and Landes at the
IEEE ultrasonics symposium in Lake Tahoe, October 1999, are also included. In
case that you are interested in this CD, please let me know. We would be
happy to send you a copy as well as some of our recent publications.

Yours sincerely

Re: Ultrasonic Modeling
I recently came across your posted question on the Forum. If you are still interested in software for ultrasonic modelling NDTSoft have software for 3D Ray Tracing in simple or complex solid model components. For more information please go to www.NDTSoft.co.uk or contact myself.

Re: Ultrasonic Modeling
I am also interested in modeling Ultrasonics.
I would like to have more information about your wave2000 software. If possible, i would like to know the mathematical base of the model,too. The problem is how accurate is the model? There are still problems in solving the equations.
Do you have any webpage describing your software?
If it is a problem talking about the mathematical base;
Basically:
1- Does your model cover immersion ultrasonic inspections
2- Is it possible to run the model both for isotropic and anisotropic materials
3- Have you done any validation including different defects?
4- Does it caover composite materials?
Thank you very much

Re: Ultrasonic Modeling
We produce Wave2000, a 2D ultrasound simulation
package. We are also developing Wave2500, a 3D-
axisymmetric package, which will be ready soon.

A demo is available on our web site
(www.cyberlogic.org)

In answer to your questions:

right now the software handles only isotropic
materials.

composite materials can be modelled, but then you
would need to model each component separately (eg,
layer by layer).

fluids and solids are modelled, so immersion type
measurements are not a problem.

the program has been shown to produce results
consistent with a wide range of experiments.

please feel free to contact us if you would like
any additional info.
