Question:
I’m modeling a 2D solar receiver (with components like a reflector, glass, insulator, and absorber) in Solid Edge for a thermal simulation in Ansys Fluent. My goal is to export the geometry as a 2D surface (Parasolid format), but I’m facing issues:
Solid Edge Export:
Assigning a nominal thickness (1 mm) lets me export as Parasolid, but Fluent interprets it as 3D.
- Converting it to 2D in Fluent causes missing parts, meshing problems (sharp edges), and boundary condition errors.
Key Challenges:
Any advice on settings, tools, or workflow optimizations would be greatly appreciated!
You can not export a 3d geometry and expect to find a 2d geometry in fluent. You have either to reconstruction Your 2d geometry using design modeler or spaceclaim since solidedge do not generate 2d geometry. An other alternative is to use the geometry you generated in solideedge and import it to design modeler or spaceclaim and use midsurface command to extract the surface you want and then delete original geometry.
Create the 2D Geometry in Solid Edge:Model as a single surface (e.g. sketch or thin wall 0 thickness).Make sure the geometry is exclusively in one of the 2D (X/Y) coordinate planes.Export STEP:Open up File > Save As > Save As type and select STEP (. stp).For 2D sketches, export as DXF/DWG, which is optimized for 2D imports.Import to ANSYS SpaceClaim / DesignModeler:
Open ANSYS Workbench → Drop Geometry (SpaceClaim or DesignModeler).
