Questions

3.28.18 Plotting Filters

clip filter can be adjusted by moving the plane, or changing the axis
plane can be be set in the GUI to x, y, or z normal
plane can be set in GUI to data normal, camera can also be aligned to the normal (axis along which the plane is adjusted)
plot over line filter
temperature at left, and temp + pres at right
filters plot over line and histogram

Volume Rendering

temperature volume
tube and glyph filters, the glyph filter requires specific adjustments
editing the “coloring” property of the volume rendering allows for opacity and color balance

4.1.18 Refresh on Volume Render Editing

color adjusted to emphasize hot regions

Color Map Editor

black body radiation preset
do not use rainbow color maps, they obfuscate details of datasets which is the opposite of our objective

Time Based Animation Controls

left appropriate color range, right range mapped from first frame

4.2.18 Text Annotations

annotate time filter and animation view
annotate time reflects the choice between snap to timesteps and real time in the amount of digits it counts through

Selections

the blue and grey box
selection with corresponding cell spreadsheet

Hotkeys:

4•3•18 Spatial and Data Element Selection

Spatial Selection

freeze selection results in the same selection being maintained
finding the minimum plastic strain
maximum plastic strain located and plotted
extract selection filter
the extracted selection can be frozen from the find data dialog

Animation

animated sphere
looped sphere animation

Blunt Fin Data Set

first look at the blunt fin data set: extract surface
streamlines, looking at incoming airflow

4.9.18 Symmetry Exploration

extract surface experimentation
color mapping
symmetric z axis view
change input dialog is used to control filter input patching

4.11.18 Pivot + Filters

[subset] Clip

scalar clipping of density
plane clipping
box clipping
sphere clipping
cylinder clipping
clip filter used to extract high pressure cells, volume rendering

[subset] Slice

crinkle slice

4.12.18 [subset] Extract Subset

subset of increasing I values
subset of increasing J values
subset of increasing K values

[subset] Threshold

threshold with increasing minimum values
threshold with decreasing maximum values
left ‘all scalars’ checked, right ‘all scalars’ unchecked which allows cells partially within the function to pass through

[subset] Iso Volume

[geometry] Transform

transform position, scale and rotation

[geometry] Reflect

minimum value x and y reflection
maximum value x and y reflection
the desired reflected view, this is true reflection not a transformation approximation

4.16.18 Fin Definition

featureEdges + reflect + extractSurface

[geometry] Glyph
