i am running a small analysis in which i have to connect components of shell elements with welds. which will give better results . results i require are displacements and stress.
which will give me acurate results tra-welds or rigids.?
and what is the difference?
tra-weld means --- connecting...
What actually MPC and SPC sounds.MPC-multi pt constrant and SPC- single point constrant.
SPC are used for fixing a component or model but MPC are use to define the relation of set of nodes with one.
what i understood is correct? or is there any additional difference between them thnxs
while using a nastran deck for creation of satic analysis deck we come across rigids to weld on component to other.can u say what is the difference between rbe3 and rbe2 (in nastran deck)
