I am trying to do an eigen value anlaysis of a model using Abaqus. I made the program run and have the result using "*Frequency" option. And the command *OUTPUT, HISTORY, VARIABLE=PRESELECT" is used to have the results. I have the eigen values and natural frequency values in ".dat" file.
Although I have the results in ".dat" file I could not view the eigen modes in Abaqus Viewer. Does anyone have any idea about what command should be written in the input file to monitor the eigen mode shapes in Abaqus viewer?
Thanks in advance,
