Beam with non unoform
Hello
I am just new in hyperwork.
I want to do displacement analysis for non unofrom beam as shown below.
i have 2 different cross section, i defined 2 hyperbeam, 2 properties and 2 component.
i use 3 nodes and use cbeam to connect the nodes, the define load step use optistruc to solve analysis, but my analytical value and value that optistruc is obtained are different.
i just thank that maybe i should use RBE2 in B, am I right?if yes how can i do that?
If no, what is my fault.
Big thanks
