Draw a Smooth Line Through Given Points in ANSYS

[nodalDOF]

Hi,

I am trying to model a turbine blade for which i would like to represent the profile as accurate as possible. I have an eqution for the blade profile to get the vertices. I would lke to generate some kepoints using profile equation and want ANSYS to genrate a smooth curve (atleast quadratic fit)through these points. Is there a command to do this in ANSYS.

I don't want to input too many points to keep the meshing easier.

L command is just drawing straight lines between points and I dont want my profile to be faceted. Any ideas on how to do this

Thanks,

I would suggest using splines (SPLINE command). This will draw smooth curved lines though up to six points. You can also define the vector at the beginning and end of the line - in this way you can join up more than one spline smoothly.

As for generating the points from an equation, probably the quickest way is simply to input the points by hand. However, you could also write a short APDL file with some *do loops to generate points from an equation if you need to do this many times.

Thankks.That was the command i needed and it worked...
