Cyclic Symmetry Question

Cyclic Symmetry Question

Cyclic Symmetry Question

(OP)
I'm performing a structural/thermal analysis of an assy consisting of 3 bodies of revolution.  I would like to use the cyclic symmetry feature but I cannot seem to define the axis of revolution.  I have centerlines defined in sketches at both the part and assy levels but none of these are selectable in the dialog.  I've even tried it at the part level but the centerlines used to define the revolve in solidworks are not selectable.  In fact, no entity in my model seems to be selectable!  Any ideas?

RE: Cyclic Symmetry Question

Hi,
I presume Cosmos works like every other FE program dealing with cyclic-symmetry: the "axis of revolution" is a predefined axis (usually Z-axis, but some programs like ANSYS allow you to define cyclicity around any axis of any coord-sys) of the appropriate coordinate system. So I suppose you will have to place a coordinate system with the proper axis oriented along the datum axis you already have.

Regards
