Mesh correction damping#
Mesh correction damping = <float_list>
Description / Usage#
- <float1>
Damping choices to be associated with Mesh correction tolerance.
Examples#
Example :
Newton line search type = BACKTRACK_MESH
Mesh correction damping = 0.5 0.2 0.1
Mesh correction tolerance = 1e-5 1e-4 1e-3
if \(L_2\) norm of the mesh displacement residual > 1e-3, the damping factor is 0.1 if \(L_2\) norm of the mesh displacement residual > 1e-4, the damping factor is 0.2 if \(L_2\) norm of the mesh displacement residual > 1e-5, the damping factor is 0.5 else the damping factor is 1.0 (no damping)
This is applied only to mesh variables when using BACKTRACK_MESH option in Newton line search type card.
These are the current defaults if not specified.
