1. A Limiting Flaw Size Evaluation is being performed. In a Limiting Flaw Size Evaluation, Signal FFS™ solves for the failure conditions of a number of different crack size (a/c) ratios. These failure conditions are sometimes out of the bounds of the tabular solution. In this event, the particular data point is left off of the curve and the above error message appears. This message is a warning only. The points on the limiting flaw curve which are returned are all from inside the table boundaries. The message is left as an explanation for why the curve may be unexpectedly truncated.

2. An arbitrary stress distribution (Weight Function) is being used. Using the stress table, Signal FFS™ generates a K Table for the specific load profile. The size of this K Table is limited by the range of stress values entered into the Weight Function. If a fatigue analysis is being performed (especially if the crack is being grown to failure), the crack can grow out of the bounds of the automatically generated table. If you are getting this error message, you may want to consider extending the stress distribution to a dimension slightly greater than the thickness. This will allow the table interpolation routine to handle the crack if it grows through the thickness. It should be noted, however, that the weight function is not recommended for use once the crack depth (a) grows past 4/5ths of the thickness (t).

To run WARP3D with the CXML solver, select Program Options from the Tools pull down menu. Then select the CXML Solver option from the Type of WARP3D File to Write option menu. When this option is selected the WARP3D input files that are created should have a "_cxml_wrp.inp" file extension. If the files are run using the Run FEA option, the program will automatically select the correct WARP3D version to run.

In addition to changing the file extension, the CXML solver option changes one line in the WARP3D input file from:
   solution technique direct sparse vss
to:
   solution technique direct sparse cxml
