i'm a solidworks beginner but an experienced engineer.
try to simulate most trivial case of a beam on pinned supports. one support is pinned ("immovble" as defined by simulation), the other support is also pinned but enable an axial translation.
forces act in three directions.
on running simulation i get "unstable model".
cant understand what is wrong with the fixures? or other reason? how do i get results for this model?
thanks for assisting me
