P. To display nodal instabilities
To graphically examine nodes and degrees of freedom on the structure where instability conditions have been reported in the output, use the following procedure.
Select the View Results group on the Results ribbon tab. The locations of instabilities are highlighted on the structure in large blue circles. The Unstable Joint table provides information on the joint number and the degree of freedom associated with an instability at that joint. An unstable condition is marked with a tool in the "1".
