Typically the propagation method that produces the least deformation for uni material is To Curve: Geodesic. This will follow the natural curvature of the part along the propagation direction rather than steering the material. If you want the fibers to follow a specifc path, then you should override the constraint with a CAD curve. Keep in mind, this will steer the material and may induce extra deformation. A third option is to use the Spine simulation method. The difference between this and the using a CAD constraint curve is deformation that is produced by steering will be localized to the region of highest curvature, then relaxed when the steering is less severe.
Whichever method you choose, it is critical that you communicate the layup procedure to/from the shop floor. If you have limited control over how the tech will lay up the part, then it is probably best to use a Geodesic constraint. If the propagation used in Fibersim does not match the real world, then the resulting flat pattern will not fit.
Finally, there is no way to interact with Fibersim while the simulation is running. Unfortunately, you have to let it complete before you can go create other objects like darts.
Hope that helps,
Hello, so Im reasearching propagation methods specifically to automated fiber placement. Does fibersim provide strategies for that or is it just handlayup and tape laying?
