`rblock facet apply`

command

Syntax

- rblock facet apply keyword ... <range>
Primary keywords:

Apply stress boundary conditions to facets. Applied forces and moments are recomputed each timestep as the facet geometry is changed. Negative values are compressive.

- gradient v
Apply a linear gradient. The value is modified by the dot product of the vector gradient with the difference of facet position and the origin.

- origin v
Specify the origin for the gradient computation.

- stress f1 f2 f3 f4 f5 f6 (only 3 components in 2D)
Apply the stress tensor to facets. The traction and moment are computed given the facet orientation. All components must be specified. In 3D, 6 parameters must be specified in the order stress-xx,stress-yy,stress-zz,stress-xy,stress-sxz,stress-syz. In 2D, 3 parameters must be specified in the order stress-xx,stress-yy,stress-xy.

- stress-normal v
Apply the normal stress to the facets. The traction and moment are computed given the facet orientation.
