Yes we can run modal analysis in abaqus.
Usually we will run this analysis to check the connectivity of the assembly, But we will have boundary conditions.
My file has no boundary conditions specified.

*FREQUENCY, EIGENSOLVER = LANCZOS, NORMALIZATION = MASS...
I had to perform a free free analysis in abaqus.
But the analysis is throwing error for unconnected region or over constrain.
Is is possible to run abaqus frequency analysis without any boundary conditions.
By running the model without boundary can we get six rigid body modes in abaqus?
