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:

All the best
