Improvements and New Facilities
in Version 14.1
Report Treeview
A new Report Treeview panel has been
introduced for use with the report generation facility.
Report generator
The report
generator allows selective model and results data to be printed or
exported to a variety of output formats. Report templates, which are saved
into the Report Treeview, are used to control the desired output. Any
number of reports templates may be created and saved with a model. Chapters
may be added model and results data, images and text files. Reports may
be exported in PDF, RTF (for use in Microsoft Word), Excel spreadsheet
or HTML
formats. Use Utilities > Report
to create an empty report template in the Report Treeview.
Fleshing on deformed geometry
When processing results the deformed beam cross-sections,
surface thicknesses and offsets can be visualised on the deformed model
geometry by using the fleshing button in conjunction with
the Deform option found on the
Geometric > Visualisations
properties dialog. This is accessed from the Attributes Treeview.
Meshing improvements for 3D models
Changes have been made to improve the quality of
elements produced when irregular surface meshing is carried out and to
also give more consistent volume meshing when imported CAD geometry is
used as a basis for a model. Improvements include:
Edge
Collapsing
Hollow
volumes
Edge collapsing
The quality of a surface mesh may be improved using
edge collapsing. Edge
collapsing removes elements with very short sides or acute angles
by merging them with neighbouring elements. This is particularly useful
when generating tetrahedral elements on imported CAD models where very
short lines are present. Edge collapsing is invoked from the Advanced
button on the Meshing
tab of the Model Properties dialog.
Hollow volumes
Hollow volumes
can be created for those situations where the defining lines and points
of the surrounding surfaces are not perfectly merged together. This can
typically occur when geometry has been imported from CAD systems, when
such merging
may be difficult or actually impossible to achieve. Once defined, hollow
volumes behave in almost exactly the same way as normal solid volumes.
For example, they may be meshed and have attributes assigned and deassigned
in the usual way. The main difference is that in a geometric Boolean operation
a hollow volume will behave like a set of surfaces, hence the name.
The user interface to enable the creation of
hollow volumes may be invoked from the Advanced Dialog of the Geometry
Properties dialog (accessed by File > Model Properties > Geometry tab
> Advanced). This option is automatically invoked when geometry is
imported from CAD.
Open hollow volumes can only be created via the Geometry> Volume> Hollow Volume> Create
menu item.
Surfaces may be added or removed from an open hollow
volume definition using the Geometry>
Volume> Hollow Volume> Add and Geometry>
Volume> Hollow Volume> Remove menu items.
Slide surfaces
When a results file is read into Modeller from an analysis
that involves slidelines, a separate named group is now created for each
slideline surface in the model - as opposed to each master and slave previously.
The print results wizard separates the slideline results
into three groups for ease of interpretation.
3D two-phase elements for nonlinear consolidation
The 2D plane strain two phase continuum elements
TPN6 and QPN8P have now been extended to cover 3D use. With the use of
the existing nonlinear material models within LUSAS these 3D elements
now provide the ability to model materially nonlinear 3D consolidation.
Internationalisation
Internal changes have been made to LUSAS dialogs
and scripts to allow for internationalisation and translation of the software.
