◆ addRigidCpl()
|
virtual |
Adds MPCs representing a rigid coupling to this patch.
- Parameters
-
[in] lindx Local index of the boundary item that should be rigid gMaster Global node number of the master node [in] Xmaster Position of the master nodal point [in] extraPt If true, the master point is not a patch node
- Returns
- true if a new global node was added, otherwise false

◆ constrainEndLocal()
|
virtual |
Constrains all DOFs in local directions at a given end point.
- Parameters
-
[in] dir Parameter direction defining the end to constrain [in] dof Which local DOFs to constrain at the end point [in] code Inhomogeneous dirichlet condition code
Reimplemented from ASMs1D.

◆ constrainNode()
|
virtual |
Constrains a node identified by two relative parameter values.
- Parameters
-
[in] xi Parameter value along the curve [in] dof Which DOFs to constrain at the node [in] code Inhomogeneous dirichlet condition code
- Returns
- 1-based index of the constrained node
The parameter value has to be in the domain [0.0,1.0], where 0.0 means the beginning of the domain and 1.0 means the end. For values in between, the actual index is taken as the integer value closest to r*n, where r denotes the given relative parameter value, and n is the number of nodes along that parameter direction.

virtual |
Generates the finite element topology data for the patch.
This method is reimplemented to check that the patch has sufficient polynomial order.
