Abaqus殼單元分析運(yùn)行終止,報(bào)錯(cuò)Too many attempts made for ? 50

瀏覽:4265 回答:4

用hypermesh抽取中面劃分殼單元后,導(dǎo)入到abaqus中設(shè)置進(jìn)行分析,分析終止只報(bào)錯(cuò)Too many attempts made for this increment。

警告內(nèi)容:

For *tie pair (assembly_channel-tie-assembly_base-tie), adjusted nodes with very small adjustments were not printed. Specify *preprint,model=yes for complete printout.


Slave node 80 instance part-1-1 will not be tied to the master surface assembly_base-tie. The distance from the master surface is greater than the position tolerance value.


Slave node 352 instance part-1-1 will not be tied to the master surface assembly_base-tie. The distance from the master surface is greater than the position tolerance value.


Slave node 440 instance part-1-1 will not be tied to the master surface assembly_base-tie. The distance from the master surface is greater than the position tolerance value.


Slave node 848 instance part-1-1 will not be tied to the master surface assembly_base-tie. The distance from the master surface is greater than the position tolerance value.


Slave node 1259 instance part-1-1 will not be tied to the master surface assembly_base-tie. The distance from the master surface is greater than the position tolerance value.


Slave node 1403 instance part-1-1 will not be tied to the master surface assembly_base-tie. The distance from the master surface is greater than the position tolerance value.


Slave node 1943 instance part-1-1 will not be tied to the master surface assembly_base-tie. The distance from the master surface is greater than the position tolerance value.


Slave node 1984 instance part-1-1 will not be tied to the master surface assembly_base-tie. The distance from the master surface is greater than the position tolerance value.


Slave node 2601 instance part-1-1 will not be tied to the master surface assembly_base-tie. The distance from the master surface is greater than the position tolerance value.


Slave node 2677 instance part-1-1 will not be tied to the master surface assembly_base-tie. The distance from the master surface is greater than the position tolerance value.


Slave node 3302 instance part-1-1 will not be tied to the master surface assembly_base-tie. The distance from the master surface is greater than the position tolerance value.


378 nodes are either missing intersection with their respective master surface or are outside the adjust zone. The nodes have been identified in node set WarnNodeMissMasterIntersect.


103 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.


202 elements are curved/warped. The angle subtended between the average element normal and a nodal normal exceeds 10 degrees. Mesh refinement is recommended. The elements have been identified in element set WarnElemWarped.

這就是模型的問(wèn)題,需要調(diào)試才可以

接觸設(shè)置不合理,單元過(guò)度扭曲。可能是adjust打開(kāi)了。建議系統(tǒng)看下軟件的接觸章節(jié)

從報(bào)錯(cuò)提示上看應(yīng)該是Tie接觸的問(wèn)題,有可能是過(guò)約束,可以調(diào)整一下接觸,比如先調(diào)整一下主從面關(guān)系

警告對(duì)求解是否成功沒(méi)影響,單元質(zhì)量差會(huì)影響結(jié)果準(zhǔn)確性;初始增量步設(shè)置為0.01求解報(bào)錯(cuò),改為0.1后求解成功。
