LUSAS User Area
Typical message given by LUSAS Modeller on attempting to
start- up or load/ manipulate a large file:
The mapping of Line #### into Surface #### deviates by more than #.##### and may lead to a distorted mesh
Most common causes & links to solutions
This message suggests
that the shape (map) of the line referenced is not fitting with the
shape (map) of the surface at the boundary defined by the line.
How to find the target Line or
Surface:
Solver error or warning messages are
also scanned from Solver .out file and reported in Modeller Text
Output window. By default the Text Output window appears at the
bottom of the graphics window just above the Status Bar. This
displays messages and warnings during a modelling session. Specific
objects referred to in error and diagnostic messages in the text
window by ID number in the form "Line #" may be
identified using the identify object dialog. The “Identify
Object" dialog is invoked by double clicking on the message
text. From this dialog the identified object may be selected, moved
to the centre of the screen, scaled to fill the screen, have its
properties displayed, or identified by an annotation arrow or a
temporary indicator.
Line # can also be located in the
model using Advanced Selection, activated by right-
clicking with the mouse in the graphics window, or via:
Edit > Advanced Selection
How to check the
mapping of the line and surface:
The
line type can be checked by selecting the line and hovering over it
and the datatip that appears will confirm if it is a "Straight
line" or a curved "BSpline line" or
"Polyline" for example. Similarly, the surface type
can be checked as being a "Planar surface" or a curved
"BSpline surface" for example. The message above
should not occur for a "Straight line" defining a
"Planar surface".
For
curved lines, the definition can be visualised more precisely by
increasing the number of facets (Geometry menu > Line
> Facet Density...) that are used to display the
curvature. In the Properties of the Geometry
layer there is also an option to colour the surfaces Solid,
which enables the surface map to be visualised. Similarly, the definition can be visualised more precisely by
increasing the number of facets (Geometry menu >
Surface > Facet Density...). It may be evident from
this that there is a problem with the surface mapping for example
and in such case the surface should be redefined in Modeller (if
possible) or in the CAD package if it is complex surface geometry
that was imported.
If the cause of this
error cannot be determined or rectified, please contact Technical
Support.
