Module: solid
Category: bc
Type string: "zero displacement"
Parameters¶

y_dof |
y-displacement | false | [] |
z_dof |
z-displacement | false | [] |
Description¶
To fix the nodal displacement degrees of freedom (dof) use the zero displacement boundary condition. This element has two required attributes: the type is set to zero displacement and the node set to which this boundary condition applies is defined via node_set. The optional name attribute can be used to give the boundary condition a name.
This boundary condition has three parameters, one for each degree of freedom. Set the value of each parameter to 1 to constrain the corresponding dof.
