Glossary¶
Bramble-specific terms used throughout the app and these docs. Abbreviations such as RANS or HPC show their meaning when you hover over them on any page.
- Account
- Your organisation's space in Bramble. It holds all its Users, data, settings and credit. See users and accounts.
- Assembly
- A named collection of Parts. Runs use Assemblies rather than individual Parts. Assemblies are organised into Assembly Libraries. See geometry.
- Attitude
- A single CFD simulation within a Run, with its own parameters (such as velocity and yaw), Template Case, methodology, workflow and post-processing setup. Each entry in a Run's Map becomes an Attitude.
- Attitude Specific Geometry
- A Map feature that swaps particular Parts for individual Attitudes.
- Baseline
- A Run that another Run is compared against. Bramble generates delta values and delta postpro against it.
- Deformation volume
- A box of control nodes placed around part of a Part. Moving the control nodes deforms the geometry inside it. See morphing and optimisation.
- Delta
- The difference between a result and its baseline. Deltas can be numbers in the Results table, or plots and movies.
- Image delta
- A delta image generated on demand in the postpro viewer from any two images.
- Kinematic Setup
- Configuration that sets default parameters, coordinate systems and moving Parts for a model. See simulation configuration.
- Lifecycle
- The sequence of stages an Attitude passes through, from Launch to post-processing. See statuses and lifecycle.
- Map
- A list of parameter sets. Each set becomes an Attitude when the Map is used in a Run. See simulation configuration.
- Mapping
- A surrogate model (for example kriging) fitted to results from several Attitudes, used to predict results between the simulated points.
- Methodology
- The solver and version used for an Attitude, for example OpenFOAM v1806F.
- Methodology Group
- The solver family a Template Case is written for, such as OpenFoam, OpenFoam with CHT or Star-CCM+. It decides which features the Template Case editor offers.
- Part
- One uploaded geometry file. Parts are organised into Part Libraries. See geometry.
- Postpro
- Short for post-processing: the automated stage after solving, and the plots, movies and forces it produces.
- Optimisation run
- A Run that simulates many deformed variants of a Part. It uses an optimisation map, whose baseline Attitude sets the conditions and whose other Attitudes each hold a set of deformation magnitudes. See create an optimisation run.
- Parameter (morphing)
- A named, reusable deformation of a volume's control nodes: Translate, Rotate or Scale. Its magnitude is chosen when it's applied.
- Pre-checks
- Automated checks Bramble runs on a case before it is meshed and solved.
- Programme
- The top level of organisation. It contains Projects and shares resources such as Parts and Template Cases. See project organisation.
- Project
- A collection of related Runs inside a Programme.
- Restricted User
- A User with read-only access to the Account.
- Run
- A group of Attitudes that share the same geometry (Assemblies) and Kinematic Setup.
- Sandbox
- A Results view that combines results from any Programmes and Projects in the Account.
- Table view
- A saved configuration of the Results table: its columns, formatting, calculations and baselines.
- Template Case
- A reusable recipe for a CFD simulation: mesh, domain, boundary conditions, solver stages, measurements and exports. See simulation configuration.
- Workflow
- The type of solve run with a methodology, for example RANS or DES.
- Zone
- A named surface within a Part. Template Cases apply boundary conditions to zones by matching their names, and forces are reported per zone. See geometry and zone naming.
