Video Interview: 3 Roles for Simulation in Additive Manufacturing

While attending the 2019 RAPID + TCT conference in Detroit this year, I was honored to be interviewed by Stephanie Hendrixson, the Senior Editor of Additive Manufacturing magazine and website. We had a great chat, covering a lot of topics. I do tend to go on, so it turned into two videos.

In the first video, we chat about how simulation can improve the use of Additive Manufacturing for production hardware. We go over the three uses: optimizing the part geometry to take advantage of AM’s freedom, verifying that the part you are about to create will survive and perform as expected, and modeling the build process itself.

You can read the article and watch the video here on the Additive Manufacturing website. Or you can watch it here:

If you have any questions about how you can leverage simulation to add value to your AM processes, contact PADT or shoot me an email at eric.miller@padtinc.com.

For the second interview, we focus on Topological Optimization, Generative design, and the difference between the two. Check that out here.

Press Release: PADT Awarded U.S. Army Phase I SBIR Grant for Combustor Geometry Research Using 3D Printing, Simulation, and Product Development

We are pleased to announce that the US Army has awarded PADT a Phase I SBIR Grant to explore novel geometries for combustor cooling holes. This is our 15th SBIR/STTR win.

We are excited about this win because it is a project that combines Additive Manufacturing, CFD and Thermal Simulation, and Design in one project. And to make it even better, the work is being done in conjunction with our largest customer, Honeywell Aerospace.

We look forward to getting started on this first phase where we will explore options and then applying for a larger Phase II grant to conduct more thorough simulation then build and test the options we uncover in this phase.

Read more below. The official press release is here for HTML and here for PDF.

If you have any needs to explore new solutions or new geometries using Additive Manufacturing or applying advanced simulation to drive new and unique designs, please contact us at 480.813.4884 or info@padtinc.com.


PADT Awarded U.S. Army Phase I SBIR Grant for Combustor Geometry Research Using 3D Printing, Simulation, and Product Development

The Project Involves the Development of Sand-Plugging Resistant Metallic Combustor Liners

TEMPE, Ariz., August 15, 2019 ─ In recognition of its continued excellence and expertise in 3D printing, simulation, and product development, PADT announced today it has been awarded a $107,750 U.S. Army Phase I Small Business Innovation Research (SBIR) grant. With the support of Honeywell Aerospace, PADT’s research will focus on the development of gas turbine engine combustor liners that are resistant to being clogged with sand.  The purpose of this research is to reduce downtime and improve the readiness of the U.S. Army’s critical helicopters operating in remote locations where dirt and sand can enter their engines.  

“PADT has supported advanced research in a wide variety of fields which have centered around various applications of our services,” said Eric Miller, co-founder and principal, PADT. “We’re especially proud of this award because it requires the use of our three main areas of expertise, 3D printing, simulation and product development. Our team is uniquely capable of combining these three disciplines to develop a novel solution to a problem that impacts the readiness of our armed forces.”

The challenge PADT will be solving is when helicopters are exposed to environments with high concentrations of dust, they can accumulate micro-particles in the engine that clog the metal liner of the engine’s combustor. Combustors are where fuel is burned to produce heat that powers the gas turbine engine. To cool the combustor, thousands of small holes are drilled in the wall, or liner, and cooling air is forced through them. If these holes become blocked, the combustor overheats and can be damaged.  Blockage can only be remedied by taking the engine apart to replace the combustor. These repairs cause long-term downtime and significantly reduce readiness of the Army’s fleets.

PADT will design various cooling hole geometries and simulate how susceptible they are to clogging using advanced computational fluid dynamics (CFD) simulation tools. Once the most-promising designs have been identified through simulation, sample coupons will be metal 3D printed and sent to a test facility to verify their effectiveness.  Additionally, PADT will experiment with ceramic coating processes on the test coupons to determine the best way to thermally protect the 3D printed geometries.

“When we developed new shapes for holes in the past, we had no way to make them using traditional manufacturing,” said Sina Ghods, principal investigator, PADT. “The application of metal additive manufacturing gives PADT an opportunity to create shapes we could never consider to solve a complex challenge for the U.S. Army. It also gives us a chance to demonstrate the innovation and growth of the 3D printing industry and its applications for harsh, real-world environments.”

Honeywell joined PADT to support this research because it is well aligned with the company’s Gas Turbine Engine products. The outcome of this research has the potential to significantly improve the performance of the company’s engines operating in regions with high dust concentrations.

This will be PADT’s 15th SBIR/Small Business Technology Transfer (STTR) award since the company was founded in 1994. In August 2018, the company, in partnership with Arizona State University, was awarded a $127,000 STTR Phase I Grant from NASA to accelerate biomimicry research, the study of 3D printing objects that resemble strong and light structures found in nature such as honeycombs or bamboo.

Automating Subsea Design (or How I Learned to Love Parameters)

In a previous life, I worked in the maritime and offshore energy industries and used ANSYS as part of my daily routine in structural design. I eventually discovered myself in a position where I was designing subsea equipment for use in offshore oil and gas fields. One thing I quickly discovered was that although subsea structures tend to be fairly simplistic looking (think playground equipment…but 10000 feet underwater) there are multiple design factors that can easily cause a domino effect that would require redesign(s). Whether it was a change brought upon by the client, tool manufacturer, or to satisfy the whims of marine warranty companies, there was always a need to evaluate multiple variants of any subsea structure.

Sounds like a very reactive process, right? So how can we bring this process into a more streamlined analysis workflow within ANSYS? Just use parameters with SpaceClaim and ANSYS Mechanical!

So what can parameters do to aid in this process?

  • Remove repetitive tasks
  • Account for geometric changes to CAD models
  • Use a range of values for material properties
  • Create associative connections between CAD models and ANSYS results
  • Allow for automatic goal driven design exploration

Now let’s look at some common use cases for parameters that I’ve run into in the past:

Accelerations for Onboard Equipment and Cargo

Cargo transported on the ocean is subject to the same accelerations that affect the vessel transporting it (surge, sway, heave, pitch, roll, and yaw). These accelerations are then combined into three representative accelerations and applied in multiple loadcases.

Typically, these loadcases are resolved in independent analysis systems but we can remove all that fluff with a simple parameter driven analysis. All one has to do is tag inputs and result items as parameters and then input values for each load case (or Design Point). In this case I have selected the XYZ components of an acceleration input applied to a mass point as well as the total deformation and maximum equivalent stress. With the push of a button ANSYS will then solve all of these design points and will amend the table to show the selected results corresponding with each design point. Results from the Design Points can be uploaded individually but this parametric analysis has made it very easy for us to determine which Design Points / load cases have the greatest influence on the design.

Geometry Influence Study

So one of the questions often asked during the design process is “Will the design work after we change this dimension to compensate for X?” which is often followed by a discussion on robustness (which is then followed by a change order). So let’s skip the discussion middle-man and move to be proactive by using parameters to quantify just how much we can change our geometry before a problem arises.

Here we have an example subsea Pipeline End Termination (PLET) structure and let’s say a client has asked us to verify if this design can work for various pipeline sizes. The PLET has some major parts that can be influenced by this change: The pipeline clamp, cradle, flanges, ball valve, and bulkhead.

Because we can use parameters there’s no need to make a new model. Merely tag items you wish to create parameters for in SpaceClaim:

Then ANSYS Workbench will start to populate its parameter tables accordingly:

We can then make certain parameters dependent on others, or define them via simple expressions. In this way we can enforce clearances and relations between the various bodies in our model.

From here all we have to do is define our variables for our future analyses:

Then tell ANSYS to solve all the design points with a single click. Note that users can create charts and tables before the solve and ANSYS will populate these live during the solution process. Individual design point results and geometries can also be reviewed at any time.

For this particular analysis we provided the same load to each Design Point but a good next step would be to set a goal driven analysis and have a range of loadings on the pipeline end of the PLET to represent various installation conditions.

Parameters are a very powerful tool within the ANSYS toolbox. They can remove repetitive tasks within FEA, easily create loadcases, and address concerns about design robustness by letting ANSYS and SpaceClaim handle CAD model rework.

That’s it for this blog post! I’ll be creating a few offshore industry-specific posts in the future as well so stay tuned!
