First since this is a truss make sure you use only one element per member (so you should have 3 elements in total – make the mesh size large enough, say 5000 mm or 5 m that you get only one per member). Otherwise it will not work if you are using truss elements (with beams it will work).<\/p>\n
For fixed support use it on the start and end vertices of your model not on the whole truss – so start vertex and end vertex of your model. That will then be as in your exercise where it is fixed at both ends.<\/p>\n
Finally and most importantly, make sure that you have connected parts in your cad via multi-body part in design modeler or sharing topology in space claim – if you do not do that they will not be connect and it will not solve. <\/p>\n
You can also still connect the members at their common vertex via merge nodes in mechanical (see help manual and search for merge nodes – if you do this you will get probably that it merged 2 nodes), that will share the nodes so they have common nodes there and are thus connected.<\/p>\n
Finally I recommend watching some videos online on how to model with beams and trusses.
\nIf you search (beam and truss and ansys workbench) you will get many hits on search engine.<\/p>\n
All the best<\/p>\n
