2.19 Release Notes

Summary

nTopology nTop Platform 2.19 is here! The release comes stacked with brand new features, such as an Import Block Manager, new Lattice Pipeline blocks, such as Custom Implicit Unit Cell and Warp Cell Map, and a new nTopCL feature for generating templates. The Import Block Manager enables you to easily manage and locate imported blocks, while also giving you the ability to unimport. The Custom Implicit Unit Cell block is a very powerful function enabling you to transform any implicit body into a unit cell to be propagated in a cell map, while the Warp Cell Map block gives you the ability to contract and expand regions of a predefined cell map. Lastly, we’ve introduced a new command in nTopCL that gives you the ability to create input and output JSON templates. As with every release, nTopology’s dedicated support team is ready to answer your questions. Please visit support.ntopology.com to gain access to helpful tutorials and support articles.

New features and improvements

Import Block Manager

  • You can now manage the blocks that you import into your file
  • To launch the imported blocks window:
    • Select File> Imported Blocks 
    • Right-click on any imported block and select the Imported Blocks option
    • Select the icon on the top right corner of the Notebook header

  • To add blocks to the file:
    • Select File > Import and choose a block from the browser 
    • From the imported blocks window, select the “Import Block” button and choose a block from the browser

  • Delete unused blocks from your file by right-clicking on the name in the imported block manager and selecting delete

  • A block can only be deleted if it is not used in the notebook. 
  • If a user tries to delete a block that is in the Notebook, an error message will appear stating that all instances of that block in the notebook need to be deleted first

Improved Feedback for Imported Blocks

When a new custom block has been imported to a file, the block will appear directly in the Notebook to let the user know that the import is successful.

  • This beam type includes the following information: 
    • Start Point: Start point of each beam
    • Start Radius: Start radius of each beam
    • Start Valency: The number of points located at every beam’s start point. This integer value is used to determine if a beam is closed, floating, or open. 
    • End Point: Endpoint of each beam
    • End Radius: End radius of each beam
    • End Valency: The number of points located at every beam’s endpoint. This integer value is used to determine if a beam is closed, floating, or open.

    • Length: The length of the beam
    • Direction: The direction of the beam as a vector 
    • Size: The number of beams in total
    • Reversed: The list of beams in reverse order

Lattice Body from Beams Block (Beta)

  • We’ve introduced a block that enables you to construct a lattice body from a list of beams. If you need to filter the beams of a lattice body based on some criteria, beam length or beam angle as examples, the Lattice Body from Beams block gives you the ability to turn those lists of filtered beams back into a lattice body for further downstream operations. 
  • Location: Beta > Lattices - Utilities
  • Description: Convert a list of beams into a lattice body 
  • Input 01: Beams
    • Type: Beam List
    • Description: Convert a list of beams into a lattice body
  • Output: Lattice Body

Rib Lattice Body from Beams Block (Beta)

  • Location: Beta > Lattices - Utilities
  • Description: Create directional ribs from the beams elements of a lattice
  • Input 01: Lattice 
    • Type: Lattice
    • Description: Lattice to generate ribs from
  • Input 02: Direction: 
    • Type: Scalar Field
    • Field to derive the normal direction from. 
  • Input 03: Height
    • Type: Scalar Field
    • Description: Field to assign height at the rib locations
  • Note: This block also includes an overload enabling you to specify a vector field for the direction input, enabling you to create your own custom offset direction.

Custom Implicit Unit Cell Block (Beta)

  • You can now create your own custom implicit unit cells in our new lattice pipeline by simply providing a single implicit body and a bounding box. 
  • Custom Implicit Unit Cell
    • Type: Implicit Body
    • Description: Implicit body to convert to an implicit unit cell. 
    • Type: Bounding Box
    • Description: Bounding box to define the domain of the custom unit cell. 
    • Location: Beta > Lattices - Unit Cells
    • Description: Constructs a custom implicit unit cell from an implicit body. 
    • Input 01: Body
    • Input 02: Unit cell domain
    • Output: Unit Cell

New Cell Map Properties (Beta)

  • We’ve introduced the following new Cell Map properties: 
    • Jacobian Determinant Scalar Field: provides a local measure of the factor by which the map expands or shrinks a unit of volume.  A negative value indicates an inversion.
    • U Scalar Field: the map to the unit cell’s X-axis
    • V Scalar Field: the map to the unit cell’s Y-axis
    • W Scalar Field: the map to the unit cell’s Z-axis

nTop Command Line (nTopCL) - Template Generation

  • We have given you a feature to create Input and Output JSON templates by running nTopCL command with ‘-t’ argument. (ex. ntopcl.exe -t myNotebook.ntop)
  • Input and Output JSON templates are generated based on the default values in the nTop Notebook.
  • Output JSON template will not be generated unless all default values are given in the Notebook.

Vector Point Map Display

    • Vector Point Maps arrows now display in screen dimensions. 
    • Using the Heads Up Display (HUD), users can now adjust the scale of the arrows, can scale arrows based on a corresponding weight derived from the simulation results, and can also determine the bounds of the visible arrows by modifying the Lower and Upper bounds of the results. See this new feature in action below:

Usage Improvements

  • The following blocks have been promoted from Beta to Production and currently reside in the Manufacturing > Slicing Menu
    • Slice Stack Boolean Intersect
    • Slice Stack Boolean Union
    • Slice Stack Boolean Subtract 
    • Trim Slice Stack
    • Simplify Slice Stack
  • The Split Mesh block has been optimized to produce faster results.
