[SpaceClaim] how to preserve curves when going into Ansys Meshing?

[e.bakhtyary]

Hi,

Is there any possibility that curves could be included in the geometry in SpaceClaim?

I realized that, apparently, curves could not be preserved in the geometry in Ansys Meshing if they come from SpaceClaim (which is not happening if it's done in DesignModeler). Since I'm meshing in 2D, I need curves along with the main surface to capture the curvature more smoothly.  

DesignModeler produces 2 parts, surfaces AND curves, which result in fine grids in Ansys Meshing. In SpaceClaim, only the surface parts are sent to the AnsysMeshing. However, I'm doing automation, and scripting in DesignModeler is quite arduous for me, I haven't found any tutorial about it.

Any help would be greatly appreciated.

By default, Line Bodies are unchecked in the Geometry Properties in Workbench.  Try checking Line Bodies and unchecking Solid Bodies.

Thanks for your answer. I've just tried that, but the curves are still missing in Ansys Meshing. I dunno why SpaceClaim omits curves while passing the geometry to the Ansys Meshing bloc........It is really annoying!😠

In SpaceClaim, I have a surface that I want to shell mesh, I also want circular beam elements along the edges of the surface to stiffen the structure.

Step 1. Select the edge curves of the surface, type Ctrl-C, Ctrl-V, to copy edges and paste curves.

Step 2. On the Prepare tab, click the Profiles button and select a cross-section for the beam. I chose Circle for this example.

Step 3. Edit the Beam Profile to give it the radius you want.

Step 4. Click on the Create button and click on each arc to convert it to a beam, also called a Line Body.

Now I have 3 beams instead of 3 arcs.  Beams are imported into Mechanical along with surfaces for meshing.

Good luck!
