One way is to convert your equation into number of points governing curve, create a text file and load it under Desigmodeler through 3d curve option. More details are available under help documentation.

What is the equation and what parameters can be varied to optimize the curve?

What is the range that each parameter can take?

I use SIEMENS NX CAD system and can create parametric curves in that.

I can import that CAD file into DesignModeler and can include the parameters for a Design Optimization in ANSYS.

Do you have a CAD system or are you limited to working in DesignModeler?

Hi

I have the same problem, can you solve it by spaceclaim, or Solidworks.

I would prefer that it could be solved by design modeler, since i then avoid converting and importing issues with units and edges.

If you wish to use Design Modeler (DM) then please follow following steps:

1. Take your equation, convert it into coordinate points (x.y and z) governing that equation.

2. Write it into 3d curve usable format (see the snapshot that I uploaded before)

3. Create text file (sample: paste following into text file (.txt)

1 1 10.1234 15.4321 20.5678

1 2 15.2468 20.1357 25.1928

1 3 5.5555 6.6666 7.7777

4. Use 3d curve option from DM

5. Upload coordinate file

It will give you the line body for your future operations. All the best.

Thank you for your reply,

Can i use the same method, if i want to create ít as a 2D sketch and then extrude?

The thing i wish to draw is a wavy channel coldplate. Where the wavy pattern is a sinusoidal function with variable amplitude and frequency.

So i need a thickness on the fin, and a height

Yes, It is possible. Convert your curve into three points coordinate system (x,y,0). Z coordinate for all points will be zero.
