『求助』请问这是什么错误

*** Warning Massless nodes
The following massless nodes were found
node # 51579
node # 51580
node # 51581
node # 51582
node # 51583
node # 51584
node # 51585
node # 51586
node # 51587
node # 51588

……………………………………………………………………省略

*** Warning total number of massless nodes = 227

The LS-DYNA time step size should not exceed 0.640E-05
to avoid contact instabilities. If the step size is
bigger then scale the penalty of the offending surface.

请问这是什么错误？
