FieldView 15 Preview

The latest release of FieldView, Version 15, is coming in late October.  This is the first FieldView release created under our Agile development process.  Participating users have seen their requests implemented in prototypes along the way and are already seeing benefits.

Among the improvements coming in the new release:

  • Increased performance and control over extract generation (XDBs), with the new option to retain thresholds from FieldView through to the XDB file.
  • An improved reader for OpenFOAM data which will allow the computation of more accurate iso-surfaces at the border between partitions.
  • Introduction of XDBView, a new standalone viewer for FieldView XDBs which is open licensed and can be freely shared among colleagues.
  • Easier access to about 50 colormaps and user defined ones straight from the interface.
  • Resolution of a bug related to the 3D mouse support improves performance for users without 3D mouse tools.
  • For users rendering very large surfaces, FieldView 15 will reduce the memory footprint while maintaining a very good level of performance.

FieldView 15 will address many more feature requests and improvements.  Stay tuned for more details as the release nears.

 

Our FieldView 15 Beta program will commence soon.  Please contact your sales or support rep if you would like to be included in the beta program.

Now! Generate FieldView XDB files directly from VisIt 2.8

VisIt users can now generate FieldView XDB files directly from VisIt scientific visualization software.  VisIt is highly scalable, open source visualization software developed by the US Department of Energy.  Intelligent Light is working under a DOE SBIR to provide a robust, hardened version of VisIt for engineering applications.  VisIt includes libsim which is a powerful tool that can be used in support of in-situ post-processing and visualization.  XDB files are generated rather than volume files for interrogation using FieldView.  XDBs help accelerate the CFD workflow also allowing researchers and engineers to ask more sophisticated questions by running more cases at higher fidelity.  These improved studies can increase accuracy and confidence and lead to new insights.

 

Researchers and engineers working on leadership class HPC systems use VisIt to work with the large datasets that result.  VisIt is built for these ultra-scalable systems, is free of licensing cost at any processor count, and is well suited for work where post-processing takes place as the simulations are run.  Writing out FieldView XDB files from Visit in an interactive session or from libsim in-situ provides persistent extract files which can then be used with FieldView software and archived in compact form for later use.  Leading users are already using the XDB export capability with in-situ post-processing.   FieldView XDB files are a fraction of the size of the original volume data yet retain full numerical fidelity.  When used with FieldView they enable both the interactive exploration of unsteady simulation data and the ready transfer of data.  FieldView is built for engineering productivity delivering powerful and accessible tools for CFD and supporting investments in high capacity, interactive and automated workflows.  This combination bridges the gap between expert users in research domains and engineering experts wishing to use HPC and in-situ post-processing in production environments.

 

Using XDBs to accelerate the VisIt workflow also allows researchers and engineers to ask more sophisticated questions by running more cases at higher fidelity.  These improved studies can increase accuracy and confidence and lead to new insights.

 

This is a significant milestone in the development and integration of VisIt with the engineering tools in FieldView that users depend on.  Intelligent Light’s development was performed largely by Brad Whitlock, a member of our Applied Research Group.  Brad is a long-time VisIt developer, formerly working for the Lawrence Livermore National Laboratory (LLNL).  Several advanced FieldView users are already using XDBs generated in VisIt.  This functionality is delivered in the VisIt 2.8 release for all users and will be supported through normal VisIt support channels.  FieldView users will also be supported through their existing Intelligent Light support programs.

Massive CFD Data Handled Quickly Without Compromise – Maximize Your CFD Investment

                This real world example uses analysis from the AIAA High Lift Drag Prediction Workshop simulations to show how XDB files enable wholly new levels of productivity for CFD.  The work was performed on a remotely located Cray XE6 system and reviewed locally.  The improvements in overall throughput can be even higher with VisIt running on the HPC systems and delivering the XDB files directly, without writing out large intermediate files.  The work discussed in the paper is was recognized by IDC with their HPC Innovation Excellence Award.

New AMD FirePro Graphics Qualified

AMD FirePro W5100We completed testing of the new AMD W5100 FirePro™ Graphics card at AMD’s request.  The new product includes 4GB of GDDR5 memory for great FieldView performance and we’ve added the product to our supported products database.

“Simply installing the AMD FirePro 5100 delivered an immediate two and a half times speedup over my existing engineering workstation graphics when when rendering turbulent structures around a real-world size Formula One CFD solution.  It was an easy productivity improvement.” – Yves-Marie Lefebvre, FieldView Product Chief

Still need more?  The larger W7100 doubles the memory and more than doubles the number of stream processors in a single slot card. For information on all the new FirePro Graphics options, visit amd.com.

ANSYS® Fluent™ 15 Released with New Parallel Export for FieldView

ANSYS® Fluent™ 15 has been released and introduces a new parallel compatible FVUNS export for FieldView. We recommend that this export be used as the default for all ANSYS Fluent datasets as it will result in dramatic performance increases. Performance increases of 5x on 8 cores are typical and this performance boost comes at no cost to FieldView users.

FieldView 14 standard licenses support use of up to 8 processor cores per dataset. For HPC users, additional scalability (32, 64, or unlimited cores) is available at moderate additional cost. Run FieldView on a local system, on-site or cloud-based server, even across virtualized resources all standard and with maximum performance.

The export is available from the FLUENT Text User Interface (TUI). Simple instructions are available from IL support.

New FieldView 14 Eliminates Per-Processor Software License Fees for HPC-enabled CFD

Early Adopters are Reporting Sustainable Competitive Advantages

FieldView is designed for scalability. Every FieldView 14 license will run on 8 CPU cores per dataset  and  high performance computing (HPC) users can run 64 or unlimited cores at moderate additional cost, eliminating often prohibitive per-processor licensing fees.  Computational fluid dynamics (CFD) data management with FieldView 14 makes it easy to work with large amounts of data that reside anywhere: on a local workstation, on-site, remote or cloud-based server without sacrificing performance.  Whether your data is measured in megabytes, gigabytes or terabytes, if you are waiting for data to copy or load, you will benefit from the speed and power of FieldView.

 

FV14 Multi-Windows and Parallel

Sixteen different variations of alpha and Reynolds number are post-processed simultaneously on screen for the AIAA High Lift Prediction Workshop. FV14 permits 8 cores to be used in parallel for each dataset (a total of 128 cores in this example) with no additional license fees.

Where innovation is the lifeblood of the business, FieldView and HPC are allowing winning organizations to outpace competitors and thrive through rapid, knowledge based product development.  Three of the top four Formula 1 racing teams are using FieldView and exploiting HPC for their aerodynamics engineering with dramatically improved results.  Small- and medium-sized manufacturers and consultancies (SMBs) are managing design risk and accelerating their pace of development with HPC and FieldView.  With FieldView 14, some key operations are 100s of times faster than in previous releases.
