《笛卡尔网格生成方法概述》，它将是非结构网格生成方法之后的又一热点！欢迎讨论！
在cfx5.5中化分好表面网格后,不能写.def文件是什摩原因,请指教,谢谢!失败的原因如下:
原因之一:
Problem: Surface meshing failed for the following CAD faces
Result: Surface mesh invalid for volume meshing!
PROGRAM CONTINUES TO ALLOW DISPLAY ONLY
--------------------------------------------------
Solid 1.41
Problem: Unable to recover boundary edge (Subr: rec_swap)
Result: Falure of surface mesher for this CAD face
Cause: Mesh spacing does not adequately resolve CAD face
and results in self-intersecting boundary edges
Action: Reduce mesh spacing in region of face
Cause: CAD model contains a sliver face
Action: Redraw CAD model to remove sliver face
原因之二:
Warning:
--------
Problem: The distance a grid node is moved from CAD edge to
CAD face exceeds 10% of local mesh spacing
Ratio = 9.168E+01%
Result: This may result in a poor quality volume mesh
or failure of the surface mesher
Cause: If the collapse face/edge option is active then
an attempt has been made to collapse a CAD face
or edge which is of a similar size to the local mesh
spacing
Action: Increase mesh spacing in region of face
Action: Do not attempt to collapse CAD faces/edges
