CSI Software performs computation with 16 digits of accuracy, some of which may be lost when analysis involves systems of significantly different stiffness, where lower-order values are truncated to suit operations with higher-order values. When lost accuracy occurs, a warning message reports the location of the occurrence such that users may edit the model if necessary.

- Less than 6 does not generate a response in that because the values and solution are sufficiently accurate.
- Between 6 and 11 lost digits of accuracy may or may not create numerical problems, therefore a warning message is reported which reads: The results of the analysis may still be acceptable but the user should carefully check the results, especially the global sums of loads.
