Change Requests
LUSAS Modeller 15.0-7
 VLO warning about files changed since installation (17781)

 If a cylindrical local coordinate system is used to transform results in Modeller, the transformed
results are incorrect (17845)
 Unhandled exception has occurred in a component in your application. If you click Continue, the
application will ignore this error and attempt to continue. Conversion from string "Lane number 1 300 kN" to type 'Integer' is not valid (17864)
 Reordering loadcases (e.g. By drag/drop or copy/paste) correctly modifies basic combinations, and
the maximum part of envelopes and smart combinations, but not the minimum parts (17871)
 When a new loadcase triggers an update of loadcase IDs, in some cases a warning is issued that
IDs in combinations and envelopes will be updated, in other cases not (17874)
LUSAS Solver 15.0-7
 An analysis with constraint equations and non-structural variables aborts with a call stack that ends
in VCIRPL (17616)

 Nothing is displayed when a point is created by snapping to a line (16357)
 The influence surface generated for a DMI attribute of type "MF (Longitudinal members)" are
incorrect. Transverse members are incorrectly considered in the calculation. This erroneous
influence surface may cause VLO to incorrectly place loads. Similarly also for types FV and
transverse. (16436)
 No arrow is drawn for Direct Method Influence of type Reaction if the direction is Nodal. (16493)
 Cannot create DMI analysis with Mesh lock on (16968)

them, after working with LUSAS for some time. (17157)
 Modeller crashes when deleting something in any treeview, sometime after using copy and paste
(17182)

limited to parallel kerbs" even when the kerbs are in fact parallel (concentric) arcs. (17184)
 In the utilities tree, the context menu on a folder (e.g. Parent folder of transformations, reference
paths, etc) refers to master and slave. These are not appropriate in this case. (17185)
 Cannot deassign load attribute assigned using "assign to all" (17221)
 Model with lift-off supports solves with no related errors or warnings but does not give results for all
the load cases when no lift off has occurred (17235)
 When setting up the checkboxes on the "Nonlinear Analysis Options" dialog in a multiple analysis
model, the checkboxes are inconsistently slaved from the base analysis - sometimes changes to
the base analysis also apply to other analyses, and sometimes not. (17249)

Load Generation dialog (17253)
 Can't add multiple Eigenvalues to included list in Print Results Wizard (17259)

product moment of area (J and Iyz) (17264)
 The beam stresses entity is not available when post-processing results from a cable tuning analysis
(17270)
 Surfaces that contain combined lines where the direction of the combined line conflicts with some
of the individual lines that make it up, can fail to mesh with linear thick shell elements (17280)
 After changing the geometry in some way (copy, move, etc) it becomes impossible to select lines or
points, or sometimes any geometry at all using the mouse. (17284)

bounds error from .Net when selecting Utilities> IMD Plus> Moving Mass> Moving Load Generation
(17287)
 Deselect master joint assignments doesn't work (17294)
 A VLO run created by editing (and renaming) an existing VLO Run uses incorrect default settings.
(17297)
 Error message "unexpected error has occurred" can be obtained after using 'copy' and then
deleting the copied object. (17301)
 Load applied to Line does not show in the line's properties - loading tab (17304)

Armer component is used as a primary component (17247)
 UDR and/or scripted results can be shown in results plots with misleading units (17265)

LUSAS Solver 15.0-2
 Incorrect results will be obtained if eccentricity is assigned to a curved quadratic thick shell element
(TTS6,QTS8). The error is proportional to the amount of eccentricity and shell curvature, and
results in an error in area and volume computation, which affects any body forces or UDLs applied
to the element. An eccentricity of one shell thickness with a large curvature (0.1) could result in
around 5% error in the fore-mentioned loads. No error will occur if the element itself is planar.
(16827)
 Illegal Jacobian Determinant error for a QTS4 element that appears to have been defined correctly
and that is of good shape and aspect ratio (16920)
 System error - BTREEF Processor for a model solve in V15 that solved OK in V14.7 (16983)
