Todas suas barras estão definidas como "compression only" . Acertando pra todas serem barras comuns em Geometry/additional atributes/advanced bar properties)elimina os avisos de instabilidade grau 1 ,que não pode ser ignorado.
All bars are defined as "compression only". Setting them all to be common bars in Geometry / additional attributes / advanced bar properties eliminates type 1 instability warnings, which cannot be ignored.
Fora isso , seu modelo tem alguns ptos onde a malha (fiz para malha com 50cm)concentra mtos nós, o que geralmente ocorre qdo há uma imprecisão na geometria.
Other than that, your model has some areas where the mesh (I set it with 50cm size) concentrates many nodes, which usually occurs when there is an inaccuracy in the geometry.
Vc deveria acertar essa imprecisão nessas areas e depois fazer a intercecção de todas as barras para obter uma malha melhor de elementos finitos
You should correct this inaccuracy in these areas and then intersect all the bars using the intersection tool to obtain a better finite element mesh
