Creating enforced displacement boundary conditions at specific locations that are not on the nodes generated from meshing

Altair Forum User

Please, I want to apply displacement boundary condition at some specific locations on my model in hypermesh (Optistruct). The locations are not on the mesh nodes.

 

Please, see the attached picture. I have the coordinates of the locations  (x1, y1), (x2, y2), (x3, y3) and (x4, y4)  and their enforced displacements (displ_x1, displ_y1),  (displ_x2, displ_y2), (displ_x4, displ_y4) and (displ_x4, displ_y4) respectively. How can I create these locations on my model and  apply the displacement boundary conditions at these locations. Note that these locations are not among the nodes generated from meshing the model. Thank you.

Hi Samuel,

 

You can split the element at that location which creates a node over there. On the same node(s) you can apply enforced displacement using SPC/SPCD
