Importing a CAD design from AutoCAD to HFSS is a faster solution. For this take help from mech CAD engineers. There after apply all HFSS conditions to the design.
Umesh Ankush Pawar Thank you for your kind reply. I am trying to import Solidworks model into HFSS and face following issues (Enclosed in the attachment). Please let me know your suggestion regarding this matter. Thank you.
The error is not related to surface strutures. As suggested above by Mr Nella, use help of a mechanical CAD engineer to make wrap sheet of metal and thickness of copper clad and add substrate to it. export the same in .stl format and then import .stl format to HFSS... in case u need help from some professional AutoCAD engineer pl share ur email id.
Use a rectangular sheet for different layers (ground, substrate and patch). The box will not work. Use a sheet over cylinder (with desired radius) and wrap it. Later you can thicken the sheet. This should work.
wraping of rectangle arround the cylinder is the best solution. take initial thickness of the sheet equal to zero. after that provide the thickness using thicken sheet.
even though you have any related issue... any time you can contact with me sir...
