---------------------------

Why and How to fix it?

Solution:

This is directly related to the Dynamic analysis Modal Dialog settings. Confirm the settings are correct. 

Example: 

Are these Modal analysis settings OK?

Answer: NO, they are not OK, they is bad settings, but where? 

Correct, the "Maximum number of modes" is set to 0.00 and "Analyze up to Cutoff" is disabled (unchecked). Therefore no modes are calculated.

Avoidance:

To fix this issue, use 1 of 2 options:

Option #1:

Enter a valid number for "Maximum number of modes"

Option #2:

Enable (check ON) "Analyze up to Cutoff", see AutoPIPE help for details on this option.
