Flexel

✓ import springable

✗ from springable import Flexel

Basic usage: create nodes and springs, solve, and visualize.

from springable import Node, Spring, Assembly # Create nodes n1 = Node(0, 0) n2 = Node(1, 0) n3 = Node(0.5, 0.866) # Create springs spring1 = Spring(n1, n2, stiffness=10.0, rest_length=1.0) spring2 = Spring(n2, n3, stiffness=10.0, rest_length=1.0) spring3 = Spring(n3, n1, stiffness=10.0, rest_length=1.0) # Assemble and solve assembly = Assembly([n1, n2, n3], [spring1, spring2, spring3]) solution = assembly.solve() print(solution.node_positions) # Plot assembly.plot()

Debug

Known issues

gotchaRest lengths must be positive floats; zero or negative values cause solver errors.

fix

Ensure rest_length > 0 for all springs.

affects: all

breakingImport paths changed between v0.x and v1.0.0; submodule imports no longer work.

fix

Use from springable import Flexel, Spring, Node, Assembly instead of from springable.x import y.

affects: 0.x

deprecatedThe old syntax using ast.Num is deprecated and will be removed in Python 3.14. Version 1.0.1 fixes this bug.

fix

Upgrade to 1.0.1.

affects: <=1.0.0

gotchaAssembly.solve() may return List[float] or generator; check return type.

fix

Wrap with list() if you need all results immediately.

affects: all
