Using Ansys Fluent’s Gradient-Based Optimization

There is a new workflow that has been developed for the Fluent CFD solver.  It is called gradient-based optimization.  It uses the adjoint solver, which computes the linearized derivatives of a single output variable with respect to all the input variables.  It then calculates separate sensitivity fields for the inputs.  Based on the sensitivity fields, it determines which inputs to change to maximize the desired change in the output variable.

The optimization tool is accessed through the Design tab in the Fluent menu.

There are several observable types that can be optimized for:

The first step in the process is to calculate a steady state solution of the problem.  Once a converged solution has been obtained for steady state solution, an adjoint solution is evaluated to either maximize or minimize the desired observable.

Once the evaluation is completed, the adjoint solution is calculated.

The next step is to use the Design Tool menu to define the wall boundaries that will be modified by the optimization process and what portions of those boundaries.

To perform an individual iteration in the optimization process, click on the Calculate Design Change button in the Design Tool window.  If you are looking to achieve a larger change to the observable, series of iterations will need to be run.  This can be done automatically using the Gradient-Based Optimizer tool.

To test out the capability of this new optimization tool, I ran a simple model of a u-bend pipe and optimized it to reduce the pressure drop through the bend by 40%.  The initial solution of the pipe resulted in pressure contours shown below.

When the optimizer was run to reduce the pressure drop through the model by 40%, the optimization history is as follows:

The resulting pressure contours and pipe geometry are shown below.

The change to the shape of the tube is not something that would be easy to determine without this tool.  It is very easy to use and will allow users to quickly optimize the geometry of their designs.

As you can see, this new capability allows one to quickly optimize flowpath shapes to accomplish optimization objectives. Hopefully you have found this useful and we encourage you to explore this and other enhancements to Ansys Fluent.

Press Release: NASA Awards PADT and Penn State University a $375,000 Phase III STTR Research Grant

When we applied for a NASA Small Business Technology Transfer (STTR) grant with Arizona State University in 2018 we had high hopes around that the idea of developing simulation and manufacturing techniques that would allow engineers to mimic structures found in Nature. Today’s win of a rare Phase III grant from NASA exceeded those hopes and further showed the space agencies’ interest in the research that PADT, ASU, and now Penn State are engaged in.

Inspired by the research of former PADT engineer and now ASU professor, Dr. Dhruv Bhate, the idea was to take a look at how nature uses repeating structures and responses to loads to optimize structures and to use 3D Printing as a way to create the derived shapes, growing geometry just as nature does. That Phase I was received well and led to a Phase II grant in 2019 to dig specifically into lattice structures. In addition to that work was the development of a topological optimization tool that could look at multiple types of loads and create aperiodic lattice topologies.

Researchers at NASA like those results enough to then grant PADT a Phase III project to further the development of the optimization tool and to connect it to a fluid-thermal optimization tool developed at Penn State under a separate NASA project. The study is called “Thermo-Fluid and Structural Design Optimization for Thermal Management” and it will look at creating structures that are strong, light weight, and have the thermal performance required for difficult launch and space-based missions.

You can read more in the press release below or here: PDF | HTML.

We are exceptionally proud of all three phases of this project because they show:

  1. PADT’s ability to work with academia for R&D that results in useful tools
  2. Our deep and broad understanding of simulation across physics
  3. How our unique expertise in Additive Manufacturing can be combined with our simulation knowledge to turn theory into practical hardware.

If you have needs in any of these areas or are just looking for a strong R&D partner that can help make your innovation work, reach out to PADT.


Press Release

NASA Awards PADT and Penn State University a $375,000 Phase III STTR Research Grant

The Grant is a Continuation of PADT’s Topology Optimization Research, Which Will Fund “Thermo-Fluid and Structural Design Optimization for Thermal Management”

TEMPE, Ariz., September xx, 2021 ─ In a move that acknowledges its excellence and expertise in R&D for numerical simulation and 3D printing, PADT today announced NASA has awarded a $375,000 Phase III Small Business Technology Transfer (STTR) grant for PADT to collaborate with Penn State University. The partners will expand research into thermo-fluid and structural design optimization to provide engineers who design next generation launch and space crafts with better ways to design more robust and efficient structures that experience loading fluids, forces, vibration, and temperatures.

The Phase III STTR grant is a continuation of the original $127,000 Phase I and $755,000 Phase II grants awarded to PADT and ASU’s Ira A. Fulton Schools of Engineering in August 2018 and December 2019 respectively. This is PADT’s 17th STTR/SBIR grant since the company was founded in 1994.

“Furthering our research in simulation and 3D printing for topology optimization and thermal management is critical to the future of aerospace development,” said Alex Grishin, Ph.D., consulting engineer, PADT. “This Phase III award underscores how valuable NASA found the work we did earlier with ASU and signals their desire to have PADT work with other universities to transform it into a tool that engineers can use to design better launch and space-based structures.”

The objective of the joint effort between PADT and Penn State University is to successfully demonstrate the integration of 3D data output from Penn State Mechanical Engineering Experimental and Computational Convection Laboratory’s (ExCCL) thermo-fluid optimization code, developed under a NASA Aeronautics Fellowship grant, into PADT’s topology optimization tool. The latter was developed by PADT under the STTR Phase II contract.

In Phase II, PADT partnered with Arizona State University (ASU) to develop and test a novel shape optimization tool that used a unique methodology for topological optimization, taking both the thermal and stress response of a part into account. 3D printing was also used to create the geometry produced by the optimization approach. Phase III will connect PADT’s tool to Penn State’s tool, which uses genetic algorithms to better handle the optimization found in thermo-fluid problems.

“Taking our tool and connecting it with the optimization capability that Penn State developed has the potential to benefit aerospace design engineers worldwide,” said Tyler Shaw, PhD, PADT’s VP of Engineering and the leader of the group responsible for this work. “This project will take the joint research one step closer to delivering on an optimization approach that, just as in nature, takes into account all loads, regardless of physics.”

The ultimate goal of the project is to continue research with internal and government funding to create a commercial product that engineers can use as an alternate way to optimize the shape of structures that see loading from multiple physics.
