RVDOF1 – Degrees of Freedom where Residual Vectors are to be calculated to enhance the modal space.

Description

Defines the degrees of freedom where the residual vectors are to be calculated.

Field

Contents

Component numbers.

(Integer zero or blank for scalar points, or up to 6 unique digits (0 < integer < 6) may be placed in the field with no embedded blanks for grid points. The components refer to the coordinate system referenced by the grid points.)

Grid or scalar point identification numbers.

(Integer > 0, for THRU option, G1 < G2)

Comments

If the alternate format is used, all points in the sequence G1 through G2 are not required, but there must be at least one boundary degree of freedom for the model, or a fatal error will result. Any grids implied in "THRU" that do not exist will collectively produce a warning message, but will otherwise be ignored.
