When modeling the non-linear behavior of the steel frame under cyclic load, the program shows the following error when assigning displacement to the beam nodes and does not apply the displacements.<\/p>\n

\n
no valid degree of freedom labels were input. the D command is ignored.<\/div>\n
 <\/div>\n
after defining displacement history in the text file, I follow the following route: Main menu >> Preprocessor >> Loads >> Define Loads >> Apply >> Structural >>  Displacement  >> On Nodes <\/div>\n
and I used Apply as a new table to read from the file and add it as a new table. <\/div>\n
