Frequent Error Messages

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.

1. 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.

2.  Click OK in the Error message dialog box.

3. Click Deformation . Note that as the computation failed, only the Deformation type of image is available.

4. Click Animate to understand why singularity was detected. Most commonly, the reasons are that a restraint or a connection is missing.

5. In this particular case, you need to assign a restraint (for example a Clamp ) to the part.

6. Click Compute .

Check the model to find which specifications are not consistent with the part or the product.

To check the material physical properties, refer to Modifying Material Physical Properties.

You can find below the methodology you have to follow to clean this document.

1. Open the corrupted .CATAnalysis document.

2. Click Close in the Incident Report dialog box.

3. Select File > Desk....

4. 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).

5. 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.

6. 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.
