Modeling Motion and Vibration for Better Reliability and.
Dynamic simulation can become complex, and knowing how to interpret the results can also be confusing. PADT’s experts in dynamics know modal, random vibration, PSD, rotor dynamics, rigid body dynamics, component mode synthesis (CMS), and cyclic-symmetric modal. Whether it’s a launch profile for an experiment going up on a rocket or resonance-induced high-cycle fatigue, we can model, assess, and fix the dynamic behavior of your products.
Metal Forming, Bird Strike, Crash, Explosive Loading; We can model that
Structural events that can only be solved in the time domain can be tricky. Throw in some fluids, an explosion or two, and a highly-nonlinear material property, and you have the type of problem we like to solve. We have the knowledge and the compute power to take on your difficult explicit dynamics problems.
Simple or complex, large or small, we know stress and strain
Structural simulation is the backbone of mechanical engineering, and it is the foundation of PADT’s simulation success. All aspects of structural including material non-linearities, contact, shell/beam/solid, large deflection, and composites, along with many other non-uniform materials properties are what we do all day, every day.
A Fundamental Understand of the Physics and the Solvers
Modeling fluid flow can be one of the most temperamental and difficult physics to model with simulation. That is why PADT focuses on training our engineers to understand mesh, turbulence, radiation, heat transfer, parallel solvers, user-programmable functions, and the physics that drive fluid behavior.
Understand and Optimize your Products Thermal Performance
Smaller, lighter, more efficient, more powerful. These are all desirable characteristics for most products. And they all make managing heat more difficult. PADT’s experience in this area, and fundamental understanding of heat transfer, translate into accurate characterization and optimization of thermal systems in any application. From a combustor liner to a mobile phone, PADT knows thermal simulation.
Explore all the possible variations of your system design
Understanding flow, heat transfer, and thermodynamics can make or break a system design. These complex networks and their optimal design often require exploring many possibilities and tradeoffs between different components. PADT’s thermal-fluid system simulation team are experts at this type of study and troubleshoot existing systems and create digital twins of existing hardware.
Electronics Cooling is about Geometry, Meshing, Fluids, and Heat Transfer
Packages and enclosures are getting smaller, and power is going. That is why many electronics and electromechanical products face thermal management issues. PADT’s experienced staff can model and then improve the cooling of everything from a BGA package to a data center. We speak EE and can handle board layouts and stackups, simplify enclosures, and optimize passive and active cooling solutions. Our expertise in CFD, heat transfer, geometry, and meshing is combined with our deep understanding of electronics packaging to help you keep your design cool and efficient.
Leverage the Gold Standard in Electromagnetic Simulation to Drive your Product Performance
RF, microwave, signal integrity, and power integrity play an ever-increasing role in product design. From a pesky cross-talk to optimizing the gain on a complex array antenna design, PADT’s experts with Ansys HFSS and Ansys SI Wave have the experience to understand customer needs and product specifications. They work with customers to model the situation and drive towards improved performance or solve a problem.
Tuning Electromagnetic Machinery for Optimal Performance
Electromagnetic devices have become the dominant power source for devices that range from microsurgery robots to electric aircraft. The days of ordering a motor or an actuator out of a catalog and dropping it in are gone. Efficiency and performance have driven the design of permanent magnets, temporary magnets, and electromagnets to a new high. PADT’s experienced engineers understand the challenges needed to simulate and optimize these machines because we design and build our own motors, sensors, actuators, and solenoids using the same Ansys tools. We can deliver the right level of simulation to allow your design team to make the right decisions in a timely manner.
We can help make sure it fits, it stays cool, and it performs
Packaging electrical system has its own challenges – shielding, thermal management, connector fatigue, joint reliability, noise, vibration, and shock. Simulating an electronics package, from encapsulated flip-chips to BGA mounting to PCB board reliability to enclosure cooling, involves the capture of multiple physics and dealing with complex assemblies. At PADT, we have been modeling chips, boards, and enclosures for decades. We can leverage tools like Ansys Mechanical, Ansys ICEPAK, Ansys FLUENT, Ansys Sherlock, and many more to make sure your products will work as shipped and continue to work long into the future.
Understanding Light and the Hardware Needed to Create, Control, and Sense It.
The modeling of optics and photonics is something PADT has supported for decades through modeling the systems around the lightpath. Thermal and structural simulation and optimization of lens assemblies, high-powered diodes, CCD cooling, and optical connectors are all things PADT’s simulation engineers have tackled. And, with the addition of world-class tools from Zemax, Lumerical, and Optis to the Ansys family, we are growing our capability to model photonics and optics as well.
Using Scripting to Maximize your User’s Efficiency
All Ansys tools come with at least one API that allows the automation of tasks. PADT has been writing scripts and add-ons to Ansys tools for over twenty-five years. Our engineers are recognized worldwide as experts in using customization to improve efficiency and lock processes down. We literally wrote the book on Customization for Ansys APDL.
Connecting your Tools so you can Focus on Engineering
One of the secrets of taking simulation to the next level is connecting different tools into an integrated solution in an efficient and robust way. Since the company’s founding, PADT has been hooking up Ansys tools to each other, other commercial products, government, codes, and home-grown software. No matter what you need integrated, PADT is uniquely qualified and experienced to make it happen.
Custom Software Solutions that merge advanced mathematics and physics with state-of-the-art computing and user interface solutions
Maybe you need a custom material for Ansys Mechanical. Perhaps a new turbulence model for Ansys Fluent. Perhaps a web interface to an entire simulation process is what you need. And, if you can’t find a standalone commercial or opensource geometry or simulation solution, it may be time to write something from scratch. Whatever your need, PADT is here to work with you or do the coding for you. We specialize in complex geometry problems, working with advanced numerical simulation methods, and efficiently implementing complicated mathematics. As day-to-day users of simulation tools, we also know how to front it all with an easy-to-use but powerful user interface.
