** ERROR 221068 ** Disconnected node node number.
All nodes in the analysis must be associated with valid elements. Disconnected nodes in the model are generally ignored, but this error indicates that a node which is not connected to valid elements has somehow been included in the analysis mesh.
Locate the node specified in the message using , and check that the mesh in that region is valid. Remesh the geometry starting from a better quality Dual Domain mesh (less high aspect ratio triangles). If the problem persists, contact Technical Support.
