MOC Steady Solution Did Not Reach Nominally Steady Before Transient

A Warning message in AFT xStream

Full Message text is:

The MOC Steady Solution did not reach a nominally steady state before the transient started.

 

The MOC Steady Solution runs a series of Block Iterations and checks the velocity change across each block. The MOC Steady Solution is considered nominally steady when the velocity change between blocks is less than the values specified in the MOC Steady Solution panel. If the velocity change across a block is never lower than the allowable change, a nominally steady state will not be reached, and this warning will be shown.

The user should increase the allowable change, increase the maximum number of MOC Steady Block Iterations, or increase the number of sections used.
