我以前一直用59单元模拟,用water table,但最近看14.0有新的变化。请问楼主用的什么方式加载的海洋环境? ...
恩,pipe59总感觉在计算波流荷载方面的网格有些问题,ansys单元帮助文档里有,你可以查看一下。SOCEAN;OCTYPE;OCTABLE命令对其进行加载。
给你个小例题(ansys帮助中的,参考一下吧;注意帮助文档里面有个命令octype命令里面少了一个逗号,下面的命令中我改过来了)
Do=1.5 ! outside diameter
th=0.1 ! wall thickness
height=10 ! wave height
CS=2 ! surface current speed
Depth=100 ! water depth
matwat=2 ! material number id of the ocean
secpipe= 1 ! section number of the pipe
idwat=2 ! id number of the ocean
idcur=3 ! id number of the current loading
idwav=4 ! id number of the wave loading
!
sectype,secpipe,pipe,,pipetest
secdata,Do,th,16 ! 16 cells around circumference
socean,idwat ! must be present for every section loaded by ocean
!
octype,idwat,basic,,idcur,idwav !这行命令流帮助文档里面少一个逗号 运行的话会出错 已改正
ocdata,Depth,matwat,0,-1,-1 ! suppress added mass and buoyancy
octable,,.5,.5,,2 ! CD = .5, CM = 2
octype,idcur,curr
octable, 0.0,CS ! input free surface current speed
octable,-Depth,0.00 ! input ocean floor current speed of 0.0
!
octype,idwav,wave
ocdata,2 ! request Stokes wave type
octable,height,8 ! wave period of 8 seconds
slist,all ! lists pipe section AND
! mentions ocean loading (socean,idwat)
oclist,all ! lists details of ocean loading |
