Hi Mark Wood
Is this a SOLIDWORKS question or an ANSYS/Fluent question?
Sorry about the huge delay, things have been pretty hectic getting ready for the start of the new semester.
First, this is a Solidworks question. I can define an airfoil with an 'equation driven curve' but can find no way to attach this as a 'parameter' to the line/airfoil.
As an example of what I'm trying to do:
(if this was for a cylinder instead of an airfoil)
- I would draw the cross section i.e circle
- I would add a driving dimension to the circle
- I would rename the dimension with 'DS' at the begining as this is the ANSYS 'parameter import key'.
- Repeat for length i.e. extrusion.
This would give me a part that's design parameters could be optimised for a set observable eg lift/drag etc
For a 4-digit NACA airfoil the eq is:
- c = chord length,
- x = position along the chord from 0 to c,
- y(t) = half thickness at a givenof x (centerline to surface),
- t = max thickness as a fraction of chord (so 100 t gives the last two digits in the NACA 4-digit denomination)
I think this is a limitation in SOLIDWORKS.
Once the equation is defined , it can not be drived by a parameter.
You may need some help from API.
Which means you can program the curve using VBA and control the parameter.
