Probably an error with the inputs. You'll have to show us the input command you used.

Dear Prof. Michael H. Scott, thank you very much for the response.The input command related to Bilin02 that has been used for the model is as follows:

uniaxialMaterial Bilin02 3 $Kspr $strhard $strhard [expr 1.0*$My] [expr -1.0*$My] $LS $LK $LA $LD $cS $cK $cA $cD $th_pP $th_pN $th_pcP $th_pcN $ResP $ResN $th_uP $th_uN $DP $DN;

Did you add the model builder to the beginning of your script: model BasicBuilder -ndm $ndm <-ndf $ndf>
