To import a surface to ANSYS in the Design Modeler, you will first need to create just the surface using a CAD program, such as Solidworks. Note that these instructions also apply to importing any part or assembly from Solidworks to ANSYS; you just need to skip the step  in Solidworks on adding Surfaces.

Method I

In Solidworks:

  • Right-click on the Features toolbar and add Surfaces if it is not already shown



  • Choose the type of surface you would like to create (extruded, revolved etc.)
  • Create your desired surface
  • Save the surface as a .STP file

 

In ANSYS:

  • Create your project
  • Right-click Geometry
  • Select Import Geometry

  • Locate your file and select it
  • Go into Design Modeler and Generate

 

Now you should be able to see your surface in Design Modeler.

 

Method II

After you have created the geometry in Solidworks and saved it:

In ANSYS

  • Create your project
  • Open Design Modeler
  • Go to File>Attach Active CAD Geometry
  • Click Generate

Now you can edit your Geometry in Solidworks and refresh it in Design Modeler after you have changed it.

 

To refresh the geometry in Design Modeler:

  • In the Details window, click Refresh>Use Geometry Parameter Values

  • Click Generate

Now your Geometry in Design Modeler will reflect the changes you made in Solidworks. 

 

Method III

 

In Solidworks you can connect the geometry to Workbench:

  • Go to Tools>ANSYS 



ANSYS Workbench will then open with the Solidworks file attached: 

  • Drag the Geometry onto the Geometry of your project 

 

  • You can then update the geometry from your CAD file directly



 

Now you should be able to update your geometry in Solidworks and refresh it in ANSYS
