DAT文件中的警告
***WARNING: THE OPTION *BOUNDARY,TYPE=DISPLACEMENT HAS BEEN USED; CHECK STATUS FILE BETWEEN STEPS FOR WARNINGS ON ANY JUMPS PRESCRIBED ACROSS THE STEPS IN DISPLACEMENT VALUES OF TRANSLATIONAL DOF. FOR ROTATIONAL DOF MAKE SURE THAT THERE ARE NO SUCH JUMPS. ALL JUMPS IN DISPLACEMENTS ACROSS STEPS ARE IGNORED
STA文件中的警告
***WARNING: There are 1 warning messages in the data (.dat) file. Please
check the data file for possible errors in the input file.
***WARNING: Some elements underlying deformable surface ASSEMBLY_SURF-INSIDE
are referenced by a *CONTACT PAIR option. In addition these
elements have material properties that allow the elements to fail.
For elements that can fail, contact should be defined using the
*CONTACT option. A element set named "WarnElemFailElemInContact"
containing these elements is created for use in Abaqus/Viewer to
help the user locate the elements.
***WARNING: Some elements underlying deformable surface ASSEMBLY_SURF-OUTSIDE
are referenced by a *CONTACT PAIR option. In addition these
elements have material properties that allow the elements to fail.
For elements that can fail, contact should be defined using the
*CONTACT option. A element set named "WarnElemFailElemInContact"
containing these elements is created for use in Abaqus/Viewer to
help the user locate the elements.
***WARNING: Each of the nodes listed below (and included in Abaqus/Viewer node
set "WarnNodeBcIntersectKinCon") participates in a boundary
condition definition (*BOUNDARY) as well as being part of a
kinematic contact definition (*CONTACT PAIR, MECHANICAL CONSTRAINT
= KINEMATIC). If a degree-of-freedom participates in both types of
constraints, the boundary condition will override the kinematic
contact constraint. In case of a conflict, it is suggested that
the penalty contact algorithm be used instead.
***WARNING: In contact pair 1, node 820 of instance HAT-1 on the slave surface
ASSEMBLY_SURF-INSIDE has 202.77 times more mass than the mass of
node 15 of instance HAT-1 on the master surface
ASSEMBLY_SURF-INSIDE. Significant contact noise may result with
the kinematic contact algorithm when the slave nodes have
significantly greater mass than the master nodes. Suggested
workarounds include setting the WEIGHT parameter so that surface
ASSEMBLY_SURF-INSIDE is a pure slave surface in the contact pair,
using mass-scaling to adjust the ratio of nodal masses, or using
the penalty contact algorithm.
***WARNING: In contact pair 2, node 1002 of instance HAT-1 on the slave
surface ASSEMBLY_SURF-OUTSIDE has 170.41 times more mass than the
mass of node 1654 of instance HAT-1 on the master surface
ASSEMBLY_SURF-OUTSIDE. Significant contact noise may result with
the kinematic contact algorithm when the slave nodes have
significantly greater mass than the master nodes. Suggested
workarounds include setting the WEIGHT parameter so that surface
ASSEMBLY_SURF-OUTSIDE is a pure slave surface in the contact pair,
using mass-scaling to adjust the ratio of nodal masses, or using
the penalty contact algorithm.
输出部分单元的应力-时间图,存在波动,看起来是不正常的。请帮忙看一下以上的警告有哪些是致命的,怎样修改较好呢?用的是ABAQUS/explicit |
