significantly differentShell Mesh failed error after update all
componentsExcessive offset of midside nodeLoad or Restraint

*
Invalid Serial Number for COSMOSMotionError occurs when starting
COSMOSMotion from Tools, Add-insCauseUsers are entering their
SolidWorks or COSMOSWorks serial number for COSMOSMotion during
installationThis is not necessary if the user has purchased only
SolidWorks Premium or COSMOSWorks Professional and
higherSolutionModify the COSMOSMotion installation and remove the
serial number from the installation

Cosworks.dllError:[...]\cosworks.dll cannot be loaded. Either
the Add-in or one of its components is missing [...]\cmotionsw.dll
cannot be loaded. Either the Add-in or one of its components is
missing. Versions 2006-2007This is due to an older version of the
file sx32w.dll located in the Windows\System32 and/or the COSMOS
main installation folderVersion 2005This is due to SolidWorks and
COSMOSWorks being on different service packsSolutionSearch computer
for sx32w.dllMake sure the sx32w.dll is located in both the
Windows\System32 and COSMOS main installation folderIn each folder
make sure the sx32w.dll is version 6.4.0.0 and dated January 10,
2005

Singular MatrixReasonsInsufficient Boundary Conditions on
modelThere are rigid body modes and your model is not stableParts
are flying off into space
SolutionCheck applied restraints and BCs Check to see if your
geometry has changed Check contact conditionsRe-run your analysis
with the soft spring option turned on and plot the
displacementsTurning on soft spring will allow you to pinpoint
where the improper restraints may be
*
Mesh and Model Volumes Significantly DifferentError occurs after
meshingCOSMOSWorks will check the volume of the mesh with the
volume calculated by SolidWorksCausesGeometry may be not be
currentTolerance may be too largeYou are using a remote mass, in
this case you can ignore the error messageSolutionUpdate all
components/Create a new studyTurn down the tolerance to resolve
smaller geometriesCheck the assigned mass properties in SolidWorks
for erroneous values
*
Shell Mesh failed error after update all componentsI issued the
update all components command after I change my geometry but I
still get a mesh failed and sometimes certain parts will not mesh.
Whats wrong?
When updating geometry only solids will be updated in your
model. The update geometry will update only the solids in your
model and NOT shellsShells are user defined and the program cannot
predict the user intentSometimes the entire shell definition will
be cleared outMay also get a mesh of only part of your model. See
example
*
Excessive Offset of Midside NodeError occurs during the analysis
when using high quality shell elements. It may also give you
Jacobian is negative for an element.CauseOne of the midside nodes
is distorted too muchUsing too coarse of a mesh around a highly
curved region in your modelGeometries with a large thickness but
small radii may cause this error as wellSolutionUse mesh controls
to refine the areas that may have overly distorted nodesUse the
thick shell formulation Plot the Jacobian in the mesh plot
*
Load or Restraint Transfer FailedNormally occurs at the
beginning of a runCauseModel geometry is not currentFaces or
entities you have used to define loads and restraints are no longer
there or have changedThe mesh is not properly resolving the face
you have applied a restraint toSolutionUpdate All ComponentsApply
mesh controls or refine the mesh to resolve selected entity
*
For shell models, the user may have selected a surface that was
NOT used to define the shell analysis
For shell models using mid-surfaces, the faces on the top and
bottom of the midplane are not the sameEg. You cannot have a split
face on the top surface and a no split face at the bottom of the
surface
*
Warning: No bonding element is generated Occurs at the beginning
of an analysis, when bonded contact is defined between geometrical
entities with a gap between them CausesSolver checks the ratio of
target element size to gap sizeGood: Element size / gap >
1.0Bad: Gap/Element sizeGap cannot be larger than 1mm
SolutionDecreasing the clearance distance by modifying the
geometry. This has pros and cons.Increasing the target element
size, but this could cause problems with the results
*
Un-symmetric results with symmetric loadingI have model that is
symmetrical but my results are not symmetrical. What happened?
Contact Conditions

Rigid BehaviorSource is vertex of shellTarget is surface or
solidHinge BehaviorSource is vertex of solidTarget is surface of

*
There are different types of behavior for bonded contact when
you specify different entities as source and targetPlease see the
COSMOS Knowledge Base for more information

Make sure to install with nothing in the serial number for
COSMOSMotionDiscuss when activation works with SNLPlease remember
that your model is a linear static modelCheck your contact
conditions, areas where there is a gap where you intended to bond
something. Shell shell mixed mesh bondingJacobian plotTalk about
