"Proven Tips, Tools, and Tactics for Profitable Simulations..."

Can You Afford Not to Hire Me?

From viscous flow Computational Fluid Dynamics (CRD) to high speed impact or large deformation Finite Element Analysis (FEA) simulations, pre- and post-processing can easily consume 80% of the total analysis time.

Preprocessing. High quality hexahedral mesh generation for complex geometries requires tremendous amounts of tedious human interaction, forming a strong bottleneck in user productivity. There are powerful interactive tools available for performing this task, but where to find an experienced user?

Postprocessing. At the same time, modern post-processing software benefits from a combination of ever-increasing computing power at lower costs, ongoing software advances, and increasing compatibility with major CAE solvers. Capabilities that were once only available to us select few fortunate enough to work in state-of-the-art Visualization Labs are now accessible to almost anyone. However, accessibility and proficiency are not the same thing.

I can save you vast amounts of time in either arena.

For years, I wrote, documented, trained, and consulted with the best hexahedral pre-processor available as an in-house expert user. I currently support several clients with rapidly generated high quality parametric hexahedral meshes.

I also spent years running the Scientific Visualization and High Performance Computing Laboratory at the Naval Postgraduate School. Today, I support other clients by quickly visualizing a wide range of fluid analysis results and, in some cases, using these visualizations to guide model development through the Verification and Validation activities.

What would you pay to receive a high quality mesh or grid in a fraction of the time that you could build it in-house? What would it be worth to be able to rapidly and deeply understand the results of your CFD runs? I charge a lot less.

Advanced Education and Experience

By 1988, I had mathematically modeled problems in fighter plane development, ordnance design, and a wide range of product liability cases. I had taken all the training courses offered for the analysis packages I was using. However, I still had no real confidence that I was producing accurate computer simulations!

One momentous day, a slightly exasperated technical support person admitted, "We have 17 PhDs in a back room writing this code. I think you need to talk with them."

I decided that, in terms of understanding, I needed to be one of them. I received my PhD in Mathematics from the University of California in 1995, specializing in non-linear PDEs.

Today, my clients are some of the top people in their fields. A short list of recent projects includes:

• investigating the WTC impact, studying both the structural interaction between plane and building as well as the dispersal of fuel,
• modeling Naval aviators' cervical vertebrae in order to better protect them from the extremes of ejection and high G maneuvers,
• visualizing the turbulent flow within the suction muffler of a small hermetic refrigerating compressor used in household appliances, and
• producing a Humvee mesh for development of new protective armor.

Years of experience have taught me that the easiest customer to sell to is the one that has previously bought my service and been happy with the experience. Following the completion of my latest project, the client assured me that "working with you, I always know I will get a deal, so I don't fret."

The vast majority of my business IS repeat business. However, every now and then, an opening forms in my schedule. The initial consultation and project estimate are always free, so there is no risk in finding out if I am the ideal person to aid your simulation efforts.

Would You Like to Save Money On Your Computer Simulations?

Time is money. If you need that mesh or visualization NOW, then contact me immediately. I attend no meetings, rarely travel to present a paper (Thank you, co-authors.) work on one project at a time, and if need be, can once again work 14 hours a day.

Unlike the software developers that offer consulting services, your satisfaction is my only priority. My company does not write, test, or sell software, so all of my time and attention can be devoted to your total computer simulation success.

Do you seem to be building almost the same mesh over and over again? Are you spending too many hours reducing your model size in order to achieve reasonable solution turn-around times? I have extensive parameterization experience and can show you how to use this technique, in a variety of ways, to drastically reduce model-generation time.

Do you need to have the highest degree of confidence in your solutions? As part of a thorough Validation procedure, you will need to be able to smoothly refine your mesh, i.e. you will need to leave the nodes of the coarse mesh in place and add additional nodes in between. This is not even possible with triangles or tets. Only a high quality quadrilateral or hexahedral mesh can quickly provide the kind of mesh convergence study that you need to perform.

"The Mesh was so Bad, NO Analysis Package was Going to be Able to Calculate a Solution"

I heard this from a friend who worked in the Technical Support Division of a major analysis company. His comment points out a very real problem. If the mesh is sufficiently poor, the effects that they generate overwhelm the actual behavior you are trying to capture.

High-speed impact, large deformations, visco-elastic materials, and a host of other modeling situations demand a high quality hexahedral mesh. No automatic hexahedral mesh generation can promise success on arbitrary geometry.

Optimization and risk assessment software provide other reasons for a parametric input file. Parameterizing the geometry in your model for either an optimization program such as LSTC's LS-OPT or for a probabilistic risk analysis program such as SwRI's Nessus, requires human interaction.

In all of these scenarios, hiring an experienced, knowledgeable, mesh generation expert will greatly shorten your modeling cycle.

Outsourcing in America

Outsourcing your most difficult nonlinear analysis problems is a cost effective way to enhance your company's productivity. You pay no health benefits, make no 401K contributions, provide no vacation or sick leave, make no office space available, and do not hire me at all except in those times that you truly need the additional help. Moreover, since I am an experienced consultant, I am used to literally "dropping everything" and providing you with the fastest possible turn-around time.

I do believe in in-house knowledge. I believe that whoever runs your analysis program should be a member of your company with, in particular, a deep knowledge of the appropriate material properties. This knowledge is a part of your company's intellectual property and has real value.

Outsourcing mesh generation protects this knowledge because I do not need the material properties in order to build the mesh. Visualizing your analysis results does not tell me how they were generated. Even beyond the proprietary agreement that I am more than willing to sign, outsourcing pre- and post-processing, but not the analysis, provides one more level of security for your company's most valuable asset: employee knowledge.

The Whole Enchilada

Of course, if you just need a quick turn-around on a small FEA project that you do not have current staff to cover, I can provide that as well. My original experience was in high-speed mechanism design and I have also studied larger impact situations, such as planes, trains, and automobiles. I am still best at transient, dynamic analysis.

Get your meshes built or your data visualized FAST by hiring an educated and experienced mesh generation and scientific visualization expert. Remember, we will discuss your project and I will provide you with an estimate for FREE, so there is absolutely no risk in contacting me.

There is an old Japanese proverb that states, "None of us is as smart as all of us." If I think that one of my consultant friends (and I know a few!) can provide you with more appropriate services than I can, then I will send you to them. After all, we each have our specialties. Moreover, if I do not think that I can save you money, then I will not take your project. This is all to say that your satisfaction and even delight is a sure thing, so you have nothing to lose!

Free your employees to complete the next project in the pipeline by outsourcing your most time-consuming task to GADAB today. You will find that the amount that you save is far more than what you will have to pay. Since you have zero risk, do not hesitate to contact me today.

Just send me an e-mail at matthew@koebbe.net or call me at (830) 456-3879 to begin simulating more efficiently. You will be glad that you did. Consider: if you do not, that growing anxiety over your project deadline is only going to get worse.

Sincerely,

Matthew Koebbe, PhD

P.S. I currently have an opening for just one new long-term client, so let me hear from you TODAY!
