Integrated Engineering Software Inc

After some online research for a 3D electric field and magnetic field calculator we landed on the LORENTZ-3EM program. The interface has been surprisingly intuitive and powerful. I specifically wanted the ability to control the program through an external coding program (mainly through MATLAB but my coworker uses Python which is also supported). They have a full API command list, as well as examples, which was very helpful in getting started. Their customer service has also been very responsive in helping me understand some specifics or fixing small bugs or implementing UI improvements. Overall I have been very impressed with the program and it has suited our needs well.

We work with IES on Magneto and Amperes for many years. Very useful for static magnetic simulations. Customer service is very reactive and take times to improve the models and answer to questions.

Coulomb is a great piece of software, and customer service has been very prompt and courteous and receptive to suggestions!

Software appears very flexible, and should be even more so once I get into the API. Customer service has been great. Free 2-hour training session was a big help getting my project started.

Our company is using KELVIN and ELECTRO software since 2004. These softwares have, at the same time, an easy approach for performing engineering studies in a short time and a high accuracy (especially the BEM method in ELECTRO). High reactivity of the technical support which is based on real scientific experts. They can easily adapt the software or advice you for preparing your simulations.

I use their software from matlab via API, which is vast and powerful. Support has been able to resolve all questions in a timely manner, including reviewing our code.

We are using Electro and Oersted at PTI Transformers for more than two decades and both programs are very helpful in designing of high voltage power transformers. Both the electric field problems and the harmonic magnetic field problems can be efficiently modelled and solved.

I have been working with Coulomb for 8 years in the field of overhead power lines. Coulomb has the advantage of offering a boundary element method (BEM) solver as well as a FEM solver. However, I can only speak to the BEM solver, since I did not yet use its FEM solver.
BEM has the advantage of being open (no box for the model needed) and usually needing much less (surface) elements and less calculation time compared to FEM. However, post processing can take much longer than with FEM. Contour plots of surface electric field stress seem very reliable and accurate. They seem to have that nailed. However, plotting graphs of the E-field along a line on the surface of eg dielectrics, can have its issues, especially, if the line or segment was not used in the design of the model. Even plotting E-field along segments of models lead to the issue, that some at some (few) points the E-field is not correct (there are outliers in the graph).
Fortunately, these are only a few points and they can be identified as outliers.
All in all, I can recommend Coulomb, and there would be more to say about its strengths, such as the possibility to restrict the specification of Dirichlet (voltage potential) boundary conditions and therefore the meshing to the most relevant surfaces of the volume to safe calculation time. This is also an advantage of the BE vs the FE method.

We tried and finally bought their Coulomb Software. Coulomb is not perfect, but it does the job well enough. More importantly, the support is really incredible. Their team has mastered their subject and can consult you not only on using the software but also in the concept. It seems to me that they are not overlooking their weaknesses and they are constantly working on improving and updating their software.

Best technical support! The software we use (Lorentz-2EM/3EM), is continously improved in a fast and agile fashion via application relevant feedback from customers.

Have recently started using Lorentz, based on colleague's strong recommendation, and found it to be immensely useful. Has a wide range of versatility and importing custom geometries works well. Also received training on the package from IES and can't speak highly enough.

This review is related to Coulomb. It is powerful software with a good user interface that uses computational resources efficiently and effectively. Highly recommend.

Integrated Engineering Software (IES) makes an exceptional ODE solver package for many physics and engineering applications.

In my case, I began working with their software in 2015 - namely the Lorentz2E package. After a training on site, I was made aware of the powerful array of accessor functions available for interfacing with their software package. This allowed me to build an automated framework to simulate, analyze, and record data for simulating a cesium sputter ion source. This work would eventually culminate in my PhD thesis research.

As is expected from complex software, there were occasionally a few hiccups and bugs, and the occasional function I needed implemented to fully automate my simulations. The excellent support staff at IES took them in stride and made sure to quickly iron out the kinks and get me back up and running.

I appreciated their patience and willingness to help me understand the finer details of how things are handled by the software.

All in all, I highly recommend this company for their excellent software and service!
