1 OMIQ srl Ingegneria di componenti e sistemi industriali Advanced Post-Processing of Flow3D Calculations using Ensight Federico Monterosso

2 Agenda A brief introduction of OMIQ A not-so-brief introduction of Ensight Post-Processing Flow3D results with Ensight EnsightCFD 3.5 Conclusions and Questions

3 OMIQ: Who we are Founded 3 years ago in Milan by 2 CFD engineers with more than 20 years experience in simulation. Focus on: Engineering Software Solutions Training and Support Computational Fluid Dynamics Analysis for Pumps, Valves, Heat Exchangers and other industrial components and systems. Centrifugal Pumps and Blowers Design Advanced Visualisation and Post-Processing for CAE Software

4 Ensight: Introduction EnSight is a software program for visualizing data from computer simulations and/or experiments. Most often used for computational fluid dynamics (CFD), Computational Structural Mechanics (CSM), and other CAE processes. Developed by, based in North Carolina (USA) focused on visualization techniques since 1994.

5 Who Uses Ensight 500+ customers, copies worldwide 19 International Distributors Mainly Used in the following sectors Automotive Aerospace Energy Defense Turbo machinery Oil&Gas

6 The Ensight Family (1) EnSightCFD Free Entry-level CFD Post-processing. Reads data from most CFD tools including Flow3D Limited model size 2 Million 3D cells, and watermark Scientific/Engineering Calculator with 100 s of functions support EnSightCFD CFD-dedicated Post-processing, EnSight CFD Reads data from all our CFD readers/formats. No model size limitation Scientific/Engineering Calculator with 100 s of functions Phone and support

7 The Ensight Family (2) EnSight Standard MultiPhysics Connecting to remote servers Saving the state of loaded data (Context Files) Transient/unsteady particle traces and pathlines Surface Restricted Particle Traces / Massed Particle Traces Elevated Surfaces and Profile Part Creation Texture mapping Reading Multiple Datasets at the same time

8 The Ensight Family (3) EnSight Gold For Compute Clusters. Parallel Post-processing using threads, MPI, and distributed post-processing in compute clusters to handle large datasets and speed up the visualization of large data. Exporter for ray-tracing software, POV-RAY. EnSight DR For Visualization Clusters Large Screen Display driven by multiple computer nodes. Virtual Reality and Immersive CAVE system support Parallel Rendering using multiple graphics cards in visualization clusters to speed the display of very large models, models too big to fit on a single graphics card.

9 Visualize,Analyze,Communicate FLOW3D (or any other simulation software)

10 Ensight and Flow3D Flow3D reader in Ensight established and robust Try to search on YouTube and you will find some great videos.. Let s use one of them to check out how Ensight works with Flow3D. Flow3D Transmission Hub Casting

11 Ensight and Flow3D So just to summarise: Ensight allows you to create a high quality visualization of your results It allows to inspect in time and space your problem. It allows to combine different simulations and compare them It allows to evaluate additional variables, to integrate them and to plot them. Finally it allows to wrap it all together in a high quality visual report

12 Ensight: Flow3D Wizard A Flow3D wizard recently introduced to automate some basic operations read in the model create some initial isovolumes of active or live cells create some isosurfaces of the appropriate variables so that the user is presented with his geometry/results. automatically setup some alternative isovolume creation flags (simple_isovolume off). automatically load in all STL files in the same directory as the dataset. Color the fluid isosurfaces with appropriate variables. Place time label on the screen.

13 Ensight: Flow3D Wizard So for example:

14 Ensight: Flow3D Wizard Further developments for the Flow3D Wizard STL direct extraction from the FLOW3D datasets reads all of the STL data contained within the flsgrf file, which is pertinent to the F3D simulation. the STL data is scaled and aligned correctly with the F3D simulation the STL data moves as prescribed by the F3D simulation.

15 EnsightCFD 3.5 and Flow3D EnsightCFD v3.5 just released Includes Flow3D reader Free Training video available on line Features interesting for Flow3D users: Multiple feature extraction: interactive isosurfaces and clip planes Calculator Quickly compute commonly needed values. Area, Mass Flow Rate, Flux Interactive Query Probes: integrated with plot facility Plotting or Graphing Plots or graphs are updated automatically in time and space.

16 Conclusions Ensight can help Flow3D users to Visualize results Analize them Communicate them Ensight also provides a useful Flow3D Wizard for automated import. EnsightCFD 3.5 is a powerful and cost effective Flow3D post-processor OMIQ offers support and advice on Ensight to Italian customers Questions?
