我最近在做水下加肋圆柱壳分析,之前用ansys做了,现在要用abqus进行对比分析,但是现在遇到了一些问题。
问题如下:
(1); OVERCONSTRAINT CHECKS: THERE ARE 20496 BOUNDARY CONDITIONS SPECIFIED IN THIS MODEL. OVERCONSTRAINT CHECKS FOR BOUNDARY CONDITIONS SPECIFIED ON SLAVE NODES OF RIGID BODIES, OF *TIE OPTIONS, OR OF *COUPLING OPTIONS REQUIRE 7 Mb OF MEMORY. IF THIS IS A PROBLEM, PLEASE TURN OFF OVERCONSTRAINT CHECKS USING *CONSTRAINT CONTROLS, NO CHECKS or INCREASE THE MEMORY USED BY THE PRE-PROCESSOR. (2);2115 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted. (3);For 1080 beam elements either the average curvature about the local 1-direction differs by more than 0.1 degrees per unit length as compared to the default curvature or the approximate integrated curvature for the entire beam differs by more than 5 degrees as compared to the approximate integrated default curvature. This may be due to a user-specified normal or due to the nodal averaging routine used by Abaqus. This difference may cause unexpected behavior of the beam and you may want to verify that the beam normals are correct for your problem. The elements have been identified in element set WarnBeamCurvature1. 哪位高手指点一二,不胜感激 之后感动了模型出现了这样的错误,一头雾水,卡在这里已经很久了, in keyword *ELEMENTOUTPUT, file "Job-1.inp", line 102124: The keyword is misplaced. It can be suboption for the following keyword(s)/level(s): output 很头痛啊,
