    Computational Fluid Dynamics The Art of the Possible PacMar Technologies is a leader in computational fluid dynamics and physics-based motion simulation and optimization. ​ Engineering Expertise: Advanced Seakeeping & CFD Analysis Engineering Development from TRL1 to TRL6 Hydro-Mechanical Simulation Concept Design Mechanical Systems Design Amphibious Vehicles Uncrewed Refueling Remote Vessel Operation Undersea Vehicle Design Case Study with AppliedCAx Building prototypes to validate designs is costly and limits innovation. PacMar Technologies has created virtual sea states in which we can simulate and optimize design iterations before constructing physical prototypes and testing in real-world conditions. We utilize advanced simulation tools STAR-CCM+ and our in-house code AEGIR in the product development cycle to validate product designs. Developing the Next Generation of Aquatic Vessels ​ As a company, PacMar Technologies prides itself on tackling tough challenges and being able to take an idea from a napkin sketch to a detailed design and simulation, then finally constructing and delivering a fully functional physical prototype that goes to the sea for in-water testing. Our Honolulu location offers an optimal setting for real-world validation as the challenging sea state and uniquely rough waters makes for a dynamic testing ground. Designs that can perform here can perform anywhere. Designing for the Rigors of the Ocean The ocean is an unforgiving environment, and the main challenge of maritime design is the sea itself. Watercraft designs and prototypes taken to the sea must be ready for those challenges and be able to overcome the dynamics of a harsh, deep ocean environment. Surface vessels, underwater vehicles, as well as amphibious vehicles, all have to deal with waves, the surf zone, currents, and wind, all coming together in an incompressible fluid - whether it's on the surface or below. Innovative Success Powered by Simulation PacMar Technologies has had many successful surface ship programs in its history. Oneof the most successful has been their Sea Blade line of surface ships. Novel in its approach to hydrodynamics and performance, they leveraged STAR-CCM+ to run simulations on "many, many" iterations, doing different benchmark comparisons against different hull designs. The most comparable hull ship is a Deep-V hull design. Looking at the Sea Blade vs the Deep-V, they showed a 23% reduction in slamming and a 50% reduction in roll response. They're also able to go up an additional 2 knots in speed. These are key metrics for operator safety, allowing the operator to not only go faster but also avoid injuring crew and damaging machinery or electronics. These designs would not be possible without having access to simulation. Without the reduction in risk, the cost of developing cutting-edge technologies would not have been possible.

  • Celebrating Women | PacMar Technologies

    Celebrating Women's History Month Article by Communications Staff We celebrate this month to remind ourselves of the many accomplishments of women throughout history, in addition to giving us a chance to reflect on the trailblazing women who lead the way for change. We asked some of our very own PMT engineers about women in history that may have been a source of inspiration to pursue a career in science or engineering – below are a few stories we would like to share. Emily Stauffer Mechanical Engineer, Bangor Office Marie Curie stands out as a source of inspiration for me. She was the first woman to win a Nobel Prize and the first person to win two of them in different categories. She is remembered for her discovery of radium and polonium, and her huge contribution to the fight against cancer. Her invention of the portable x-ray machine (called Little Curies) during WWI saved a lot of lives. She built these x-ray machines and recruited other women to help her bring them to the frontlines to teach doctors and nurses how to use them on wounded soldiers. Her influence is so significant that my husband and I have chosen to name our daughter, who will be arriving very soon, after her. Her name will be Lillian Curie. ​ Eric Hultgren Dire ctor of Power and Energy, South Kingstown Office My older sister, Gretchen Barnes, inspired me to study and pursue a career in engineering. Gretchen studied mechanical engineering at Rensselaer Polytechnic Institute. I loved visiting her on campus and was always amazed about what she was working on. Her enthusiasm was contagious and that solidified my desire to become an engineer. When I finished graduate school, I was fortunate enough to work with her. For over 20 years, she was one of my top technical and programmatic sounding boards. After all these years she still inspires me to keep growing and learning both personally and professionally. Love you Gretchen. ​ Kayla Rasavanh Mecha nical Engineering Intern, Honolulu Office There is not a specific woman in history that has inspired me to pursue a career in engineering. My source of inspiration to pursue engineering came from a few of my fellow female lacrosse teammates and the advice they gave me. I was in between majors, and they were both studying mechanical engineering. The curriculum and their internships sounded really exciting to me, so I decided to try it out. Both have now graduated and are working, one at an environmental engineering firm, and the other is a nuclear engineer. The field of mechanical engineering is dominated by men, and because of that, women are able to create a community within one another. Watching my friends lead successful careers and knowing there is always someone who has my back and wants me to succeed is what inspires me to keep going. ​ Whether an 18th century two-time Nobel Prize winning scientist, or a few influential people in your life that champion your accomplishments, there is inspiration that can be found all around us. Inspiration can propel a person from apathy to possibility. Here at MDG we wanted to recognize a few of our colleagues and their sources of inspiration – it is our talented employee base that makes this company such a unique place to work, thank you Emily, Eric, and Kayla for sharing your stories with us! » back
