ANSYS® Fluent® 16.0 Enables FieldView HPC Capabilities

FieldView Parallel Export from ANSYS® Fluent® 16.0

 

ANSYS Fluent 16.0 provides the capability to export results to FV-UNS while maintaining the partitioning established for a FLUENT parallel solution.  The file is fully compatible with FieldView Parallel allowing for the substantial time savings from parallel processing.  Every FieldView license will support at least 8 processor cores.  FieldView Parallel will readily scale to 64 processors and beyond.  The export files can be automatically generated during the solver run.

 

Surface Export – From the ANSYS Fluent TUI a new option called “fieldview-unstruct-surfaces” creates a surface only FV-UNS export, where the user selects the exported surfaces from a list of boundary conditions and post-processing surfaces (iso-surfaces, planes…).

  • Surface export for Parallel FieldView – A surface export made from a parallel session of Fluent will maintain the partitioning of the surfaces, and the resulting file can thus be read in parallel by FieldView.
  • Interior surfaces may be selected for export in Fluent 16.0.  This is a longstanding request and is useful in applications like integrating flow rate or seeding streamlines on control surfaces.  Please contact our support team for information about how to use this new feature.

FieldView and FLUENT – Power for Unsteady Simulations

 

Unsteady simulations are often post-processed and reviewed using FieldView XDB files which are a fraction of the size of volume data.  Exporting surface data, reading into FieldView Parallel and then having FieldView post-process and produce XDB files can be entirely automated.  This workflow delivers lightweight XDB files for review in FieldView or by the free XDBview reader. When exporting from ANSYS FLUENT, the resulting file can be read into FieldView in parallel, dramatically reducing the read-in time.

VisIt and FieldView HPC – DOE Highlights In-Situ

Intelligent Light is using SBIR grants to tap the
power of VisIt, a visualization program supported in
part by the Advanced Scientific Computing Research (ASCR) program in the Department of Energy (DOE) Office of Science.

 

Intelligent Light was selected as a trusted vendor who could provide the expertise and discipline to tailor tools to industrial workflows while commercializing and hardening the government developed code.  Intelligent Light is providing industrial grade software development, engineering service and customer support to end users.

 

The project enables Intelligent Light to hold down development cost and end-user investments by utilizing open source code developed by DOE.  Moreover, the project is helping Intelligent Light customers move to in-situ post-processing years earlier than if IL had developed all of the required technology from scratch.

 

Eric Brugger and other Lawrence Livermore National Laboratory scientists designed VisIt to visualize the mounds of simulation data DOE supercomputers generate. It’s built to scale well and it’s well suited for in situ processing.

 

“VisIt … is an open-source code, free to download and modify, as thousands of researchers have. With no licensing fees, merging VisIt into FieldView will hold
down costs for small- and medium-sized companies using it on HPC systems.”

Intelligent Light responded to a call by ASCR to harden and commercialize DOE-supported software for high performance computing applications, making the tools robust and accessible.  Working under a Phase II grant of nearly $1 million, Intelligent light is integrating VisIt into our FieldView HPC suite. The funding is from a U.S. Small Business
Innovation Research (SBIR) program, which provides capital for early research and development with commercial potential.

 

VisIt’s big-data capacity allows FieldView to handle a wider range of CFD visualization tasks. “But ‘if you want to turn it into a commercial product, you really have to spend the time to customize things to people’s workflows,’ Brugger says. ‘We’ve customized it to our workflows in the DOE community,’ but it doesn’t always fit other users workflows.”

 

ASCR recognized it needs help to move VisIt and other DOE-supported solutions for high-performance computing into commercial use. Through the SBIR program, it called
for small businesses able to take DOE codes and “shrink wrap” them into accessible tools.

 

The collaboration “shows DOE is taking its research and development and spawning new technology – which is one of our missions,” says Benjamin Grover, division leader for
Applications, Simulations, and Quality at Livermore.

 

With a Phase II grant of nearly $1 million, Intelligent Light is integrating VisIt into its FieldView HPC suite. Later this year, customers will be able to choose either the standard FieldView code or VisIt to visualize CFD data.

Agile development at IL delivering greater customer responsiveness and satisfaction

Intelligent Light has made a major commitment to revamping our development process using agile development methods.  This change was made to increase our responsiveness to customer needs.

 

We look to our users to share their needs and help us set the direction for product development.  Moreover, we involve our customers in the development and testing process prior to release so we can be sure we are meeting their needs.  This direct involvement has lead to many good ideas being recognized and these ideas have improved the implementation of several new features for all.  The changes have impacted all engineering projects and the impact is already seen in FieldView 15, XDBview, and in  FieldView services projects and applied research.

 

“FieldView users from the Aerospace and Formula One industries have been key in designing both FieldView 15 and XDBview, making sure we had it right the first time”, says Yves-Marie Lefebvre, FieldView Product Chief.

 

As the goal is to increase responsiveness, the new process will help us deliver multiple releases each year, improve our adherence to schedule commitments, and enable more rapid deployment of new features and fixes.

 

“Every customer involved so far in our Agile Development Process has expressed satisfaction and the will to get involved even more,” Lefebvre continues.  “But this is just the beginning. And we’re expecting more of our users to join the movement”.
