**unshared_middle_nodes#

Description#

This command creates a node set made up of unshared nodes by adjacent elements (e.g. linear/quadratic) in a mesh. The created node set can be used afterwards to apply MPCs on the unshared nodes to avoid spurious numerical solutions.

Syntax#

**unshared_middle_nodes \(~\,\) [*nset_slave alt_name]

*nset_slave

allows to give an alternative name for the created nset instead of the default name “unshared_slave_nodes”.
