#127 Create RBE3 element using HyperMesh tcl

To create an RBE3 element with dependent node 100 and independent nodes 101,102, and 103 with all of the nodes having all six degrees of freedom and a weight of 1.23

*rbe3 mark_id independent_dofs dof_size independent_weights weight_size dependent_node dof weight

mark_id: The ID of the mark containing the independent nodes. Valid values are 1 and 2.

independent_dofs: The ID of the integer array containing the degrees of freedom for which each respective independent node of the element is active (any of the digits 1-6), created using *createarray. Must be set to 1.

dof_size: The size of the independent_dofs array.

independent_weights: The ID of the double array containing the weight for each respective independent node, created using *createdoublearray. Must be set to 1.

weight_size: The size of the independent_weights array.

dependent_node: The dependent node of the element. If set to 0, the dependent node will be auto-created at the centroid of the independent nodes.

dof: The degree of freedom code for which the dependent node of the element is active (any of the digits 1-6).

weight: The weight assigned to the dependent node.
