求各位大神指导一下

88 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.

OP=NEW on *CONTACT is ignored when the general contact definition is specified as model data.

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

There are 3 warning messages in the data (.dat) file.  Please check the data file for possible errors in the input file.

 The elements in the element set WarnElemSurfaceIntersect-Step1 are involved in surface intersections. Refer to the status and message file for further details.
