transform_surface_uniform_load

opstool.pre.transform_surface_uniform_load(ele_tags, p=0.0)

Converts uniform surface loads into equivalent nodal forces in the global coordinate system. According to the static equivalence principle, the distributed load is equivalent to the node load.

Note

This function will automatically call the NodalLoad Command to generate nodal loads. However, you need to create timeSeries and load pattern objects externally in advance. The load generated by this function will belong to the load pattern closest to it.

Parameters

ele_tagsint, list, tuple, np.ndarray

Surface element tags.

pfloat, list, np.ndarray, default=0.0

Uniform surface load magnitude (per unit area) along the surface normal direction. The positive direction of the normal is obtained by the cross-product of the I-J and J-K edges. If a list or numpy array is provided, the length should be the same as the number of elements.
