Eigenvalue output frequency =========================== .. code-block:: none Eigenvalue output frequency = Description/Usage ----------------- This optional card is used by LOCA to determine how often to call the ARPACK eigensolver during a continuation problem. When this value is selected to n, ARPACK will be called on the first continuation step and every nth step thereafter. n can also be set to -1, in which case ARPACK is called only after the last continuation step. The default value is -1, in which case ARPACK is called on the last continuation step. Examples -------- Here is a sample card: :: Eigenvalue output frequency = 2 Technical Discussion -------------------- This card is useful for continuation problems when it is not desired to calculate eigenvalues at every continuation step, enabling time to be saved. This card is not applicable to the eggroll eigensolver, which cannot be used during continuation. Theory ------ No Theory. FAQs ---- No FAQs. References ---------- No References.
