Problem when creating a surface
Altair EmployeeHello,
1, when I create a surface throught lines, sometimes the surface is not according exactly the lines. I do not konw why there is this small change. How can the edge of surfaces be exactly accroding to lines?
<?xml version="1.0" encoding="UTF-8"?>
2, I checked also the instruction of command
*splinesurface entities mark plane_flag plane options
*surfacesplineonlinesloop mark_id fill_gaps use_surfs options
there are some options for this problem? Especailly for the option with Bit values, I do not know how to use it.

Hi,
1.Can you try with the ruled option,that create surfaces and/or meshes of plate elements from nodes, lines. Instead of selecting the whole line try selecting the first half of the line and create surface.

Hi George,
thank your for your answer. Could you tell me why there is this problem? I know that it works if I choose the first half because there is only a simple suface. But for my working script it is not good method.
And for your suggestion 'ruled option', could you explain more ? Better with a picture of the command. Sorry I am freshman to Hypermesh.

Hi,
This could be because of the geometry. Select first half and create a surface, similarly do it for the other half and check whether the surface is properly created.
In 2D page you will get ruled option.
I'm attaching a document on ruled option and also a tutorial where this option is covered.
Since you are a beginner in HyperMesh I recommend you to download our ebook on Practical Aspects of Finite Element Simulation (A Study Guide) which covers all the basic theoretical concepts in FEA with exposure to HyperMesh.
