我做钢管混凝土节点分析,命令流如下,计算承载力时出现类似下面的警告(挑了些),而且没有结果文件,请帮忙分析下,急啊!
*** ERROR *** CP= 6.609 TIME= 11:47:12
Last input displacement for element 7041 must be positive.
*** WARNING *** CP= 29.234 TIME= 12:26:51
Real constant 4 referenced by at least element types 3 and 2.
*** WARNING *** CP= 29.297 TIME= 12:26:51
Nodes I and J of element 6708 ( COMBIN39 ) are not coincident. 加弹簧单元加了法向、切向和横向的,是不是加的方法的问题?
*** ERROR *** SUPPRESSED MESSAGE CP= 50.141 TIME= 12:33:29
Nodes I and J have been defined as duplicate nodes
for element 6787 ( COMBIN39).
*** WARNING *** SUPPRESSED MESSAGE CP= 7.031 TIME= 12:48:04
Element 1 has a diameter to thickness ratio less than 10. Theory may
not be valid.
Check real constant table 5.
