- 14:28, 24 June 2025 User macro to flip the boundary codes (hist | edit) [8,460 bytes] S g (talk | contribs) (Created page with "Consider the problem of mimicking the behavior of a standard load/unload experiment that is displacement controlled up to the point where the load cell reads zero force and the machine then switches to load control. In a FEAP computation the boundary codes on the driven nodes can be dynamically changed by changing the values in the <code>ID(ndf,numnp,1:2)</code> array. In particular if for a given dof and node number the value of <code>ID( , , 2)</code> is set to zero...")

When used with incremented parameters, this becomes a powerful technique for meshing. Consider the geometry found in the paper M.M. Ameen, O. Rokoš, R.H.J. Peerlings, M.G.D. Geers, Size effects in nonlinear periodic materials exhibiting reversible pattern transformations, Mechanics of Materials, Volume 124, 2018, Pages 55-70, ISSN 0167-6636, https://doi.org/10.1016/j.mechmat.2018.05.011.
