Okay，thanks a lot !
There is another questions I want to ask。it is that almost all the examples I know have no drop in displacement curve。So I want to know if it is because the material or element they choose lead to the result ，and if i want that drop part to be realized ，what kind of materials or elements should I define？can I find them from Wiki or any article
I downloaded an example about limit state material which incude some tcl files. So I want to input it to navigator. However,there are some error shown in the command window of Matlab as follows
Unable to read line (20) “set dataDir Analysis_LimitStateMaterial(Load)-Pushover”
Error using eval
Undefined function or variable ‘bcTag’.
Error in ReadTCLfile (line 450)
Error in LoadModel (line 140)
Error in LoadModel (line 78)
especially,there are no line 450
