Good Morning - not sure you saw the previous post, but if you do the below change then you should get very similar results I believe (assuming you have the same material properties, dimensions, cross sections, boundary conditions, in Sofistik and Ansys):
HI @lbtung248

You are using truss elements in SOfistik, but beam elements in Ansys -
So mesh with only one element per structural member (so set you element size to 10 m or something very large to get one element per member), and the choose link/truss type (which is a truss element) under the line body definition and model type details/

See here on how to do that (set it to link/truss instead of beam):

All the best
