Drawing a sin wave
 

Just wondering if anyone knows how to draw a sin wave in when defining the geometry of a system?

I'm doing the the shear flow over different surfaces to see how it affects the flow, but the only way I can get that plate geometry is using the spline tool

Any help would be most appreciated.

Hi,

Generate points' coordinate for your curve and save as *.dat file.
Read *.dat file using Import->vertex data.
