I am trying to design a component which has triangular spikes on one of its surfaces(similar to the image). I am new to this software. Please help me. ! https://images.app.goo.gl/jpufnvsUc1gT6uxa7

What kind of "design" problem are you having? For example: 1) You don't know how to draw the geometry? 2) You don't know what physics/module to choose? 3) You don't know what boundary and/or symmetry and/or source conditions to choose? 4) You don't know how to choose/set-up the mesh? 5) You don't know how to tell the software what kinds of plots or tables of data you wish to generate/look at in post-processing? If you describe your problem in more detail and with as much specificity as possible, then you are much more likely to receive helpful advice.

I am not able to draw the triangular spikes (more accurate image linked). I dont know what geometry to use. I think a triangular wave using parametric curve will get the job done but I couldn't find a triangular wave equation that works in parametric curve. https://drive.google.com/file/d/1deHwJYmBWbQ1VH6pe2u75pNQ3gAyoR79/view?usp=sharing

  1. Create a workplane.
  2. Draw your 2D structure, using the polygon tool.
  3. Extrude your structure into 3D. I've attached an example. In the workplane, I used the polygon tool, the array tool, and the union operation.
