请教;为什么我的一个二维autocad图导入algor 单元选项没有二维呢
.dxf格式的 稳态定常热分析 图形必须在YZ平面上才能使用2-D单元 原帖由 chuman 于 2008-7-2 10:15 发表 http://www.simwe.com/forum/images/common/back.gif图形必须在YZ平面上才能使用2-D单元
做个记号。。
algor中仍然有其它类似默认规定。比如如果模型荷载中涉及到静水压力,那么应使模型的y轴置于水深方向,以正确定义静水压力的y参考。 原帖由 cavingao 于 2008-7-2 10:22 发表 http://www.simwe.com/forum/images/common/back.gif

对块单元是这样,但对plate单元,还是可以沿任意方向的。 原帖由 chuman 于 2008-7-3 16:30 发表 http://www.simwe.com/forum/images/common/back.gif

也就是说 如果是壳单元,y参考也可以是x参考或者z参考么? 详细地说,对于线性分析,如上面所说:
For brick and tetrahedral elements, the hydrostatic pressure is always applied increasing in the -Y direction.Specify the Y coordinate that corresponds to the top of the fluid in the "Y Reference" field.
For plate elements, the hydrostatic pressure can increase along any direction.First specify a point on the top of the fluid in the "X", "Y" and "Z" fields in the "Point on Fluid Surface" section.Then specify a vector that is normal to the surface of the fluid and points into the fluid using the "Surface Normal of Fluid" section.
而对于非线性分析,则都可以沿任意方向的:
The hydrostatic pressure can increase along any direction.First specify a point on the top of the fluid in the "X", "Y" and "Z" fields in the "Point on Fluid Surface" section.Then specify a vector that is normal to the surface of the fluid and points into the fluid using the "Surface Normal of Fluid" section. 明白了,多谢chuman兄~
