请教：可以帮忙解决一下这几个运行中遇到的错误吗？十分感谢，急用
我是个初学者老师让建一个十七层的大楼模型出现了这几个错误，希望能帮我一下，多谢！1.*** WARNING *** CP = 23.156 TIME= 14:41:30
Unselected line 4.
2. *** WARNING *** CP = 40.000 TIME= 14:41:47
After NUMMRG,ALL, node 13730 (and possibly others) is associated with
more than one solid model entity.Future commands which depend on the
node to solid model connectivity (meshing, mesh clearing, solid
boundary condition transfer, etc.) may not operate properly.
3. *** WARNING *** CP = 40.609 TIME= 14:41:49
Real constant 1 referenced by at least element types 1 and 2.
4. *** ERROR *** CP = 671.812 TIME= 14:53:00
Large negative pivot value ( -1.636456384E+14 ) in Eqn.system.May be
because of a bad temperature-dependent material property used in the
model.
5. *** WARNING *** CP = 672.000 TIME= 14:56:36
Small negative equation solver pivot term encountered at ROTY DOF of
node 100565.Check for an insufficiently constrained model.
