Hi,

I am a complete beginner to ansys software and yet came with such a challenging task. I want to simulate (make a 3d model at first) a very complex sine-log antenna type. I made an exact graph of it in matlab (screenshot below) and I need to somehow import it in ansys to extrude it as an upper copper layer of the pcb... I have some freedom in terms of the format of the picture (I can export it as pdf or other type of file from the matlab), but I have to keep the proportions very precise, so can you at least guide me through the steps. What actions do I have to take to achieve the described goal?

Hi,

Thank you for reaching out to the Ansys Learning Forum.

It is possible to draw the geometry in AEDT HFSS itself if you are drawing this model in Matlab using design equations. Please go through “Drawing an Equation-Based Curve” section in the HFSS help document available under the Help menu for more detailed information.

Best regards,
Praneeth.

Hello again,

Thank you for your help. After investigating the software for some time I came up with the equation based curve, but it is not showing up in the ansys project environment. Any observations on my mistakes or what could be wrong in this setup? Thank you again.

Hi,

Did you adjust the units in the fields for curve creation? The supported units for drawing equation based curve is meters. Please do not use units in equations as there are not supported. More details on this can be found in “Drawing an Equation-Based Curve” section of the HFSS help document.

It looks like you are using a very old version of the application. Please note that some functionalities differ for older versions.

Best reagrds,
Praneeth.
