ADINA二维流场内流固耦合问题,总出现ADF2072
模型如下图所示固体部分为两个薄片,设置了两组流固耦合界面.
流体
固体
计算时报错ADF2072, 看错误提示应该是合流固耦合界面间隙过大有关.
但是如果将下部或上部薄片去掉后,使用相同条件即可计算...模型的尺寸上应该没有问题..,
求各位高手给予指点!!

** ERROR ** CODE ADF2702:
Fluid node (label) 2806 is not attached to solid fluid-structure
interface 1. The relative distance to solid boundary element
51 is 1.00E+01.
The fluid nodal coordinates are (0.00E+00, 5.00E+01, 5.00E+00)
The points and their coordinates of the solid boundary element are:
point 21 = ( 0.000E+00, 5.000E+01, 6.000E+00)
point 66 = ( 0.000E+00, 5.000E+01, 6.100E+00)
Possible causes are:
* Fluid-structure interfaces in fluid and solid models are not
coincident;
* Solid boundary elements are too coarse compared with fluid boundary
elements on the same fluid-structure interface.
Recall that fluid-structure interfaces are specified in both fluid and
solid models. They must be coincident with each other. However, it is
normal to have a small distance between fluid nodes and solid
fluid-structure interfaces if meshes of interfaces in both models are
not matched.
The relative distance here is defined as the ratio of the distance between
the fluid node and the closest solid boundary element to the length of the
solid boundary eleme
流固耦合面编号不对应 这样的编号应该怎么编呢？ 楼主这个问题解决没？ qdshuanger 发表于 2011-12-9 14:31 static/image/common/back.gif
流固耦合面编号不对应
这个应该怎么解决呢? 我也遇到这个问题 一直没找到解决的:Q方法 qdshuanger 发表于 2011-12-9 14:31 static/image/common/back.gif
流固耦合面编号不对应
问题解决,谢谢!
问题已解决, 结果如图:P
楼主 能传一下能算的模型文件？
