abaqus errors

hi dears

i have som problems in my project that should be simulated  with abaqus .

The
elements contained in element set ErrElemExcessDistortion-Step2 have distorted
excessively.

There
is only one excessively distorted element

The
ratio of deformation speed to wave speed exceeds 1.0000 in at least one
element. This usually indicates an error with the model definition. Additional
diagnostic information may be found in the message file.

The
elements contained in element set ErrElemExcessDistortion-Step2 have distorted
excessively.

Abaqus/Explicit Analysis exited with an error -
Please see the  status file for possible
error messages if the file exists.

HOW can i solved this error about rate of deformation?

plz help me as soon as possible
