This section gives you information and solutions when an error message
appears.

Why does the "Singularity detected" error message appear?
If a singularity is detected while launching the
computation operation, the following error message appears:
The part or the product is not fully constrained. You have
to add the missing specifications.
 |
To find the missing specifications you can generate
deformations images (Visualizing
Deformations) or displacements image (Visualizing
Displacements) and then animate the generated image (Animating
Images). |
 |
For example, you can open the
sample31.CATAnalysis
document from the samples directory.

-
Click Compute
,
select the All option in the Compute dialog box and click
OK.
As a result an error message appears. |
 |
In addition, an exclamation mark
lets you know in the specification tree (assigned to the Case
solution feature) that a singularity was detected. This
exclamation mark will appear either when you expand/collapse the
tree or still when adding or updating a generated image. In other
words, you will be able to know, visually speaking, which
computed solutions are singular and which computed solutions are
not singular. |
-
Click OK in the Error message dialog box.
-
Click Deformation
.
Note that as the computation failed, only the Deformation type of
image is available.
-
Click Animate
to understand why singularity was detected. Most commonly, the
reasons are that a restraint or a connection is missing.
-
In this particular case, you need to assign a
restraint (for example a
Clamp
)
to the part.
-
Click Compute
.

Why does the "Entity cannot be updated" error
message appear?

Some inconsistencies were found on the part or the product.
 |
Check the model to find which specifications are not consistent
with the part or the product. |
|

Why does the "Invalid material
characteristic" error message appear?

This error message may appear when you launch a
computation.
|

Why does the "Finite element
model is corrupted" warning message appear?

This error message may appear when you open a .CATAnalysis
document that is corrupted.
 |
You can find below the methodology you have to follow
to clean this document.
-
Open the corrupted .CATAnalysis document.
-
Click Close in the Incident Report dialog
box.
-
Select File > Desk....
-
Right-click the corrupted .CATAnalysis document and
select CATDUAV5....
The CATDUA V5 dialog box appears.
For more information about the CATDUA V5, refer
to Infrastructure User's Guide: Advanced Tasks: Using the
Data Upward Assistant (CATDUA V5). |
-
Clean the .CATAnalysis document.
To do this:
-
Click Clean.
-
Click Run.
-
Click Exit when the clean operation
is finished.
For more information about the CATDUA V5, refer
to Infrastructure User's Guide: Advanced Tasks: Using the
Data Upward Assistant (CATDUA V5): Using CATDUA V5 inside an
interactive CATIA Session: Clean a CATIA document. |
-
Save the cleaned .CATAnalysis document (even if the
CATDUA V5 does not detect any errors).
You can now reopen the .CATAnalysis document. It is not
corrupted anymore. |

Why does the "Condensed Stiffness Matrix is Greater than the Limit of 24Gb" error message appear?

This message may appear after Stiffness and Constraint computation, when the solver tries to
remove constrained DOFs from the stiffness matrix. It means that the resulting condensed stiffness matrix is too large because there are too many DOFs in kinematics relations. You can either use a coarser mesh or redefine your kinematics relations using fewer nodes.

Why does the "More than 16Gb of memory is required for computation." error message appear ?

This message may appear in the factorization step when the size of the frontal matrix is greater than 16Gb. Even if there is no size limit for the factorized matrix, this size of the frontal matrix is a limit for the solver.
You can use a coarser mesh.
