Bulk Data Entry This parameter can be used to request only the modes (structural or coupled) that satisfy the upper bound of frequency, for PCH output.

Parameter Values Description
UFREQPCH <Real> (Hertz)

No default (See Comment 3)

Modes with frequencies above this value are not output in the PCH file.


  1. This parameter only applies to PCH output and does not affect the calculations during the simulation.
  2. This parameter works for complex eigenvalue and normal mode analysis, but only for the structural modes or coupled modes.
  3. If PARAM, UFREQPCH is used without specifying a value, the simulation will error out.
