Specifies the handling of the previous eignesolution when repeating a dynamic analysis. Select N (for no) to perform a new eigensolution. Select Y (for yes) to skip the eigensolution and reuse the results of the earlier analysis, and only perform calculations for displacements, reactions, forces, and stresses. This option is only valid after an initial eigensolution is performed and is still available. The mass and stiffness parameters of the model must be unchanged or the previous eigensolution is invalid.
