在进行上述材料定义后进行分析计算,结果在计算到第4阶是出现错误:如下:Mechanica Structure Version K-03-47:spg
这样的情况是因为材料定义错误出现的吗?如果是将如何解决/

Memory allocation for block solver: 128.0
Memory allocation for element matrices: 2.0
Checking the model before creating elements...
These checks take into account the fact that AutoGEM will
automatically create elements in volumes with material
properties, on surfaces with shell properties, and on curves
with beam section properties.
Generate elements automatically.
Checking the model after creating elements...
No errors were found in the model.

The design study terminated abnormally.
The model is insufficiently constrained for the analysis.
Please review the element connections, properties, and
constraints.
You may be able to locate your model's problem area by
using Mechanica database ID numbers. ID numbers can be
queried using the "Entity ID" macro in Pro/MECHANICA
Standalone. The following ID numbers are associated
with this error:
111770
113136
113140
113144
113148
113150
113204
114342
114346
114354
The unconstrained degree of freedom can be seen by running
a constrained Modal Analysis with rigid mode search.
Animating the rigid modes will display the unconstrained
degrees of freedom. If the error still occurs, then the
issue could be caused by material properties or unattached
spring/mass idealizations.
