Hello everyone. i need help with drawing a wavy wall inside a rectangular duct using ansys space claim equation function. I'm trying to get a wavy wall using the sin equation function. Thank you.

Where are you having difficulties? Are you able to use the equation editor to create the sine form? If not, you may need to change some options. From the File pull-down menu select SpaceClaim Options. In the window that pops up select Extended (the one below Navigation, I am using the German version so my translation may be different). On the right side there should be something like “Enable constraint based sketches (restart required)” or something similar. Uncheck this box and restart SpaceClaim. Now the equation editor is available.

If you have the equation editor available, what are you having difficulty with? I would create the sine-wave pattern as a separate body and then combine them when I am happy with the sine form.

I don't have difficulties enabling the equation function. I can generate the wave equation, I'm having difficulty converting the walls of that rectangular duct wall into a wavy wall.

Can you explain at what point in the process you are having difficulties? Are you able to make a sine surface body? Can you pull this to create a solid body? Are you have problems combining the solid body and your square tube? Without an understanding of what you are having trouble with, it makes it difficult to assist you.

Pictures do tell 1000 words.

Walk me through your process of getting the wavy wall in the rectangle duct wall (as highlighted) in the image above. Thank you.

I basically did in the last post. Create your Sine Surface body. Extrude it in the direction of the amplitude to create a volume. Move it if necessary. Combine with tube body.
