I am trying to analyse an aluminium frame but sections to be used are not in database so I tried USERTABLE and made 2 sections First is 30x20x1.4 mm channel section and second is SHS 40x40x1.4 . After runing analysis it throughout an error as in subject line...... I read other posts regarding this same issue but could not reach to solution how previously it was solved for others.
