many frames instead of one. Is it possible to create less frames?

*Answer:* Dividing or meshing of frame elements is required to get accurate results for certain types of analyses, such as buckling or dynamic analysis. Subdividing frame elements for buckling analysis enables *Answer:* To generate accurate results for certain analyses, [frames|kb:Frame] must be explicitly subdivided, or assigned automatic [meshing|kb:Meshing], where the object is handled as a single member, but meshed into multiple segments for analysis purposes. Frame objects should be subdivided in the following situations:
