Flashpoint

AQA improvement. (2023.2)

Boundaries automatically classified Blocking has been extended to include those created by Edit =>

Trim by Surfaces,
Trim by Curves.

Included only Trim Geometrically with initial AQA release.
AQA’s flood fill approach to automatically forming larger quilts will stop at these hard boundaries.

Flashpoint

AVM improvement. (2023.2)

It is now possible to define user specified center of the volume extents. Previously it was always relative to the centroid of or extents of the selected surface grids.
It’s now possible to consistently use the same far boundary extents among various sets of domains with varying extents.
Selecting the option adds an additional XYZ text field for specification of the point directly.
The center can also be picked in the Display Window from any typical pickable locations.

2024.1 – Volume Meshing Performance Improvements

Faster, more efficient meshing

Fidelity Pointwise further improved unstructured block initialization in several ways:

T-Rex now employs multi-threading to deform the T-Rex front. On average, this improvement results in a 3.5X speed up compared to 2023.2 (and 5X speed up compared to 2022.2) for the T-Rex portion of block initialization for large meshes.
Voxel meshing is more robust and up to 2X faster compared to 2023.2 for large cases.
Weighted Condition Number smoothing is now much more robust and less sensitive to relaxation factor as compared to 2023.2. New controls were added to prevent smoothing of cells within the T-Rex portion of the mesh.

Reduce the time and resources required to initialize large meshes
