class project_heart.lv.modules.lv_base.LV_Base(enums={}, *args, **kwargs)#
create_spring_rim_bc(bc_name: str, surface: str, dist_from_c: float = 10.0, height: float = 2, r_alpha: float = 0.8) → dict#

Adds information for boundary condition at defined surface. The current setup creates a ‘rim’ geometry at a distance from the surface’s center and relates the ‘rim’ nodes with the surface nodes based on closest distances. This setup is used to create springs during FEA simulations as BCs.

Parameters

  • dist_from_c (float, optional) – Perpendicular distance determining the offset from surface’s center. Defaults to 10.0.

  • height (float, optional) – Height of the rim. Defaults to 2.

  • r_alpha (float, optional) – Percentage of found surface’s radius. Will adjust the radius of the rim based on surface_r*r_alpha. Defaults to 0.8.

Returns

Rim data. Keys are defined based on LV_RIM Enum.

Return type

dict

est_centroid() → numpy.ndarray#

Estimates the centroid of the geometry based on surface mesh.

Returns

[x,y,z] coordinates of center

Return type

np.ndarray

set_aortic_info(aortic_id=LV_SURFS.AORTIC, border_aortic_id=LV_SURFS.BORDER_AORTIC, add_virtual_nodes=True) → None#
Sets aortic information for other computations, such as boundary conditions. Creates ‘aortic_info’ dictionary with radius, center, and mesh ids. If border information is provided, it adds information for the border as well.

If ‘add_virtual_nodes’ is set to true, it will create virtual node information based on respective centers.

Parameters

  • aortic_id (int, str or Enum, optional) – identification of aortic nodeset. Defaults to LV_SURFS.AORTIC.

  • border_aortic_id (int, str or Enum, optional) – identification of border aortic nodeset. Defaults to LV_SURFS.BORDER_AORTIC.

  • add_virtual_nodes (bool, optional) – Whether to create virtual node information.

set_base_info(base_id=LV_SURFS.BASE, add_virtual_nodes=True) → None#

Sets base information for other computations, such as boundary conditions. Creates ‘base_info’ dictionary with radius, center, and mesh ids. If ‘add_virtual_nodes’ is set to true, it will create virtual node information at center.

Parameters

  • base_id (int, str or Enum, optional) – identification of base nodeset. Defaults to LV_SURFS.base.

  • add_virtual_nodes (bool, optional) – Whether to create virtual node information.

set_mitral_info(mitral_id=LV_SURFS.MITRAL, border_mitral_id=LV_SURFS.BORDER_MITRAL, add_virtual_nodes=True) → None#

Sets mitral information for other computations, such as boundary conditions. Creates ‘mitral_info’ dictionary with radius, center, and mesh ids. if border information is provided, it adds information for the border as well. If ‘add_virtual_nodes’ is set to true, it will create virtual node information based on respective centers.

Parameters

  • mitral_id (int, str or Enum, optional) – identification of mitral nodeset. Defaults to LV_SURFS.MITRAL.

  • border_mitral_id (int, str or Enum, optional) – identification of border mitral nodeset. Defaults to LV_SURFS.BORDER_MITRAL.

  • add_virtual_nodes (bool, optional) – Whether to create virtual node information.
