OspGrillage.analyze_influence_surface#

OspGrillage.analyze_influence_surface(**kwargs)#

Create and run a dedicated 100 kN roving-point influence-surface analysis.

This analysis is stored separately from ordinary load-case results and is retrieved via get_influence_results().

Parameters:

  • name (str) – Influence analysis name.

  • x (iterable) – Iterable of global x coordinates for the roving point (legacy rectangular-grid mode).

  • z (iterable) – Iterable of global z coordinates for the roving point (legacy rectangular-grid mode).

  • longitudinal_stations (iterable, optional) – Optional iterable of longitudinal mesh station values (from Mesh_obj.nox) for admissible deck sampling.

  • transverse_stations (iterable, optional) – Optional iterable of transverse mesh station values (from Mesh_obj.noz) for admissible deck sampling.

  • x_step (float, optional) – Default spacing used to generate x coordinates from the deck extent.

  • z_step (float, optional) – Default spacing used to generate z coordinates from the deck extent.

  • y (float, optional) – Model-plane y coordinate. Defaults to 0.

  • point_load (float, optional) – Point-load magnitude. Defaults to 100e3.

Notes#

When neither x/z nor station lists are provided, the default surface is generated from the mesh station grid (admissible deck points), not from a global rectangular bounding box.
