LUSAS TreeviewModelling with LUSAS

LUSAS Civil & Structural has an easy to use, associative Modeller for modelling and results processing and a fully integrated Solver which can be used independently if required. A comprehensive set of menus, dialogues, tool bars, buttons and forms are supported by a set of modelling and results processing wizards. On-line help is provided.

Models are created using feature-based geometry with wizards provided for specific applications. CAD import and export of model data is provided. Model attributes such as material properties, mesh types, thicknesses and loadings etc. can be named explicitly and are displayed in a Treeview where they can be assigned to selected geometry of the model using the ‘drag and drop’ technique.

Fleshing (the visualisation of assigned geometric properties) helps ensure that the geometric thicknesses and eccentricities of slabs and the orientation of beam members are correctly defined. 

Boolean operations allow complex geometry to be defined by combining, subtracting or intersecting existing Surfaces or Volumes. Surfaces representing holes can be 'punched' into an existing surface and any mesh arrangement will be automatically adjusted around the inserted opening. 

A multi-level undo/redo facility allows quick modelling corrections to be made. 

Built-in associativity ensures that if the model geometry is amended, all assigned loadings, supports and other attributes are automatically moved to suit.

Layers and Windows

Models are formed of layers where the visibility and properties of each layer can be controlled and accessed via the layer name which is held in the Treeview. As the model is built up, model features may be grouped together and manipulated to speed up data preparation or to enable parts of the model to be temporarily hidden. 

Gota TunnelAn OpenGL implementation provides fast graphical displays. Multiple graphical windows allow simultaneous displays of different parts of the model at different orientations. Modifications made in one window are automatically updated in other views. Powerful cursor selection, full pan and zoom and dynamic rotation allows for easy viewing of your model. 

Libraries of Section Properties and Materials

  • Standard steel section libraries include UK, US, EU, Korean, Australian and Canadian steel  sections
  • Pre-cast section libraries for selected countries
  • User-defined section libraries
  • Section property calculator
  • Common materials property library
  • User-defined materials

Desktop Integration and Customisation

The user interface is a full native Windows 98/NT/2000/XP implementation providing an Open Interface to ActiveX compliant Windows software such as Excel, Access, Word and other engineering software. Customisation of menus, toolbars and dialogues and the ability to create your own wizards with Visual Basic Scripting is provided. With these features you can tailor the system to your company’s specific requirements and automate the design and analysis of repetitive structures.
