Introducing …

EnSight 10.1

Summary Overview

• ~18 months development• 10.0

– Was mostly a user interface release• GUI redesign• Right-click, drag and drop, windows interface

• 10.1– Is mostly a engine and transmission improvement

• Poly-faced elements, OpenFOAM, STAR, Fluent• Right click to command language• Myriad of misc improvements

Part Tagging

• Quickly Changing the Part Selection using the Keyboard– Alt-1 - assigns the current selection to tag #1– Cntl-1 - makes the parts in tag #1 selected

• 10 tags (0-9)• Suggestions:

– Assign a tag to the fluid domain part(s)• To use as parent parts for creation

– Assign tags to parts you will use often– Assign tags to parts with volume rendering– Use tags to help build groups

Feedback

Part Tagging

• Save/Restore from Context files

• Save/Restore from Archive files

• But not in command file

Smooth High Quality Shading

Fast rendering of spheres

New Rendering for Spherical Point parts with modern graphics card

• Old Graphics Card (OpenGL earlier than 3.3)– Spheres rendered as polygons– 100MB/million spheres (client memory)

• Newer Graphics card (OpenGL 3.3 and later)– Vertex buffer object base point-sprite approach– Spheres are rendered as textured circles– Up to 40x faster– Unlimited number of spheres

Polyhedral performance improvements

• 40% less memory than EnSight 9.0 for pure "average" polyhedral dataset

• Better rendering of actual model elements using edge flags

• Clips without holes• Polyhedrals automatically changed to Zoo

elements if applicable

Edge Flags

• 10.1 utilizes “edge flags” to show the boundary of the 2d element.

10.0 10.1

Contour Labels – Custom Position

• Place labels where you want• Labels now go on levels and sublevels

Quick Color

• When select anything that has a color attribute will populate “large” swatch

• Can drag any of the colors from a swatch to any object that has a color

• The “little” swatches are stored colors– Which are persistent on restart

• When an object has more than one color we choose the most likely

– Drop on a contour part we color the part, not the contour labels

Auto Foreground Color• When viewport 0 background color is set, change

white/black foreground colors based on contrast

RMB and choose White background

Particle Traces

• Tubes

Particle Traces

• Turn visibility off for any one trace • Set the color of any one trace• Must be done via right-click

Part Clones• A “copy” part has limitations that many users do not

understand. Also not possible to “leave behind” a part.

• “Clone” creates an all new part identical to the selected part– Created or Model parts– Has no dependency on the part it was cloned from

• But dependent on the same parts as the part that was cloned

• “Clone” Replaces “Copy” on RMB– Copy is still avaialble from Edit pulldown

Group Transform

• Alternative to Frame Mode• Much easier

– Do not need to create a frame, assign it, transform it, etc.

• Works with keyframe animator

• Visual only, i.e., no periodicity

• Is hierarchical, i.e., parts transform through all the group transforms

• RMB – Edit Group Transform

RIGHT-CLICK ON A GROUP

Group Transform

Group Transform

There are 3 ways to transform / rotate geometry in EnSight.

1.Frames - Offers the most flexibility but also most complicated (only on client)

2. Group Transform - Put your parts in a group and transform / rotate / scale the group (visual only on the

client).

3. Rigid body - Rotation/translation on the server

Case Linking

• Make case comparisons easy– Making some assumptions– Will probably get many users most of the way

• Then the user unlinks the cases and finishes up “manually”

• Step 1 – Load the first case. Perform (or not) some tasks

Case Linking

• Step 2 – Load the next case

ON OFF

Case Linking

• The cases are now “linked”– The new case goes into a new viewport

• The viewports are linked at a low level

– Part edits and creations are across the cases– Variables are created across the cases

• New calculator function to do a case difference– Case map with a subtract of the base case to get Delta

– Queries are created across the cases• And plotted on a single plotter

– Interactive probes are performed through all cases

Case Linking

• Current Limitations– Parts are linked by part number, i.e., what you do to the first part in case

1 is duplicated to the first part in case 2• The parts must match up one for one in the same order

– Variables are linked by name, ie., “Temperature” must exist in all of the cases.

– Up to 4 cases can be linked

– Once you unlink the cases you can not relink them

– Uses context files – so whatever limitations context files apply

– You must turn on case linking before you add the second case• There is no “catching up”

Reuse Context on Case Replace

Element Filters

• Earlier version of EnSight have a single filter– And required a per-element scalar variable

Element Filtering

• Filtering “Out”

• Up to 6 Filters

• Model Parts

• Nodal or Elemental Variable

• And/Or Filter Options

• Sequential

• Non-destructive (no undo necessary) 11

•New: y1+ Dist

•Polyhedral support•Improved algorithms

•Python scripts

Calculator Functions: New, Better & Faster

• New– CaseMapDiff– SpaMeanWeighted– IJKValues

• Improved– CaseMap

• Faster– In 10.0, perhaps 8 threaded calculator functions

– In 10.1 Almost all of them are now threaded

Threaded Calculator Performance

• EnSight Standard, 8 threads• EnSight Gold, unlimited threads• Cores and hyperthreads• ENSIGHT10_MAX_THREADS
