Element data for supported element types in STEM. The data contains the following information: - ndim (int): number of dimensions - order (int): element order - n_vertices (int): number of vertices - reversed_order (List[int]): reversed connectivity order of the element - edges (List[List[int]]): edges of the element, line edges of each element
- class stem.globals.GlobalSettings(gravity_value: float = -9.81, time_step_precision: float = 1e-08, geometry_precision: float = 1e-08)
Bases:
objectClass containing global settings for the stem package. These settings can be modified by the user to adjust the behavior of the package.
- Attributes:
gravity_value (float): The gravitational acceleration value in m/s². Default is -9.81 m/s².
time_step_precision (float): The precision for time step calculations in seconds. Default is 1e-08 s.
geometry_precision (float): The precision for geometry calculations in meters. Default is 1e-08 m.
