*** WARNING *** CP = 18.047 TIME= 16:31:13
Real constant 31 referenced by at least element types 2 and 4.

*** WARNING *** CP = 18.047 TIME= 16:31:13
Real constant 20 referenced by at least element types 1 and 4.

*** WARNING *** CP = 18.047 TIME= 16:31:13
Real constant 45 referenced by at least element types 2 and 4.

*** WARNING *** CP = 18.047 TIME= 16:31:13
Real constant 46 referenced by at least element types 2 and 4.

*** WARNING *** CP = 18.047 TIME= 16:31:14
Real constant 47 referenced by at least element types 2 and 4.

*** WARNING *** SUPPRESSED MESSAGE CP = 18.047 TIME= 16:31:14
Real constant 19 referenced by at least element types 1 and 3.

*** WARNING *** SUPPRESSED MESSAGE CP = 18.047 TIME= 16:31:14
Real constant 36 referenced by at least element types 1 and 3.

*** WARNING *** SUPPRESSED MESSAGE CP = 18.047 TIME= 16:31:14
Real constant 52 referenced by at least element types 1 and 7.

*** WARNING *** SUPPRESSED MESSAGE CP = 18.312 TIME= 16:31:18
The program chosen initial timestep/load-factor is arbitrary. It is
necessary for the user to supply a suitable initial
timestep/load-factor through the NSUB or DELTIM command for
convergence and overall efficiency.

*** WARNING *** SUPPRESSED MESSAGE CP = 23.500 TIME= 16:31:27
Coefficient ratio exceeds 1.0e8 - Check results.

*** WARNING *** SUPPRESSED MESSAGE CP = 29.219 TIME= 16:31:35
There are 61 small equation solver pivot terms.

*** ERROR *** SUPPRESSED MESSAGE CP = 29.312 TIME= 16:31:35
The value of UZ at node 16291 is 2.950580274E+20. It is greater than
the current limit of 1000000. This generally indicates rigid body
motion as a result of an unconstrained model. Verify that your model
is properly constrained.

我只算个自重，都不能算，请问是怎么回事？
