提示模型 不稳,对角线系数大于1e11是怎么回事?
计算中out文件中出的错误,如下
(A) BOUNDARY CONDITIONS -
THE B.C. MUST NOT ADMIT A RIGID BODY DISPLACEMENT OR ROTATION OF THE TOTAL STRUCTURE.
(B) DELETION OF DEGREES-OF-FREEDOM - ALL D.O.F. AT NODAL POINTS WITHOUT STIFFNESS CONTRIBUTIONS FROM ELEMENTS MUST HAVE BEEN DELETED
(C) ELEMENT GEOMETRY AND CONNECTIVITY -
ALL ELEMENTS MUST HAVE BEEN INPUT WITH
PROPER NODAL NUMBERS, AS DESCRIBED IN
THE USERS MANUAL.
(D) ELEMENT INTEGRATION ORDERS -
THE ORDERS OF NUMERICAL INTEGRATIONS FOR
EVALUATION OF ELEMENT MATRICES MUST BE
SUFFICIENTLY HIGH.
(E) MATERIAL DATA -
ALL MATERIAL DATA MUST BE PHYSICALLY
REASONABLE (E.G. YOUNG*S MODULUS MUST
BE GREATER THAN ZERO).
*** IN MATERIALLY NONLINEAR AND/OR LARGE DISPLACEMENT ANALYSIS ***
IF THE MODEL HAS BEEN INPUT CORRECTLY (WITH ALL
THE ABOVE CONSIDERATIONS TAKEN INTO ACCOUNT), THEN
THE COLLAPSE LOAD OF THE MODEL HAS BEEN REACHED.
我的命令流文件如下附件
请各位大虾帮帮忙看看
