Modular-Data

Modules – general

● Organize model in separate units

● Hierarchical Layout of module in tree-like structure

(similar to layers)

● Connection of modules through boundary

conditions/link elements (typically one level above)

● Modules contain mesh, boundary conditions, etc.

and may also contain other modules

● Each module has its own namespace

Modules in Animator

● Full support for general tree● References by modulepath● Modules have names und IDs● Default-Module

● References are interpreted relative to it● Access by full path available everywhere

● Internal IDs● Unique numbering of complete model

Modules - Commandsyntax

● Path specification: bracketed list like in command targets● Simple item reference:ide pid [Car][Chassis]:5000

● Item referenz with slot:ide pid 1[Car][Chassis]:5000

● In target definition:s[1[Car][Chassis]]:ide pid 5000

Modules – Command syntax (2)

● Special character for root module: /

● Default module: mod def <Path> i.e.:mod def [/][Car][Chassis]

ide dst pid 5000 pid [/][Barrier]:5000

Distance will be measured between[/][Car][Chassis]:5000

and[/][Barrier]:5000

● Root is initially default → in case of a single

module: ⇒ no changes in workflow

Modules – Command syntax (3)

● Default behaviour: Include all submodules

● Reference without submodule: append empty brackets []

mod def [/][Car][Chassis][Wheels][Front]

ide pid 5000 → 5000, [Left]:5000, [Right]:5000

mod def [/][Car][Chassis][Wheels][Front][]

ide pid 5000 → 5000

Modules – GUI – Import Model

● Simple module tree display of geometry

● No PID-filtering with modular models!

● Later: Import only selected modules

Modules – GUI - Slotmanager

● Module tree display

● Define default module

● Display of current default module

Modules – GUI - Partsdialog

● Tab “Parts” automatically switches to modular mode

● Display of (sub-)modules and their contained parts in a tree structure

● Actions defined for parts are also available for modules

Modules – Colour mode

● Separate colour mode col mod mod● Colourize parts by module membership col mde ...● Assign colour to current default module directly in slot

manager● View dependent
