NodeGenericODE2

A node containing a number of ODE2 variables; use e.g. for scalar dynamic equations (Mass1D) or for the ALECable element. Note that referenceCoordinates and all initialCoordinates(_t) must be initialized, because no default values exist.

Additional information for NodeGenericODE2:

• This Node has/provides the following types = GenericODE2

The item NodeGenericODE2 with type = ‘GenericODE2’ has the following parameters:

• name [type = String, default = ‘’]:

  node’s unique name
• referenceCoordinates [\({\mathbf{q}}\cRef = [q_0,\,\ldots,\,q_{nc}]\tp\cRef\), type = Vector, default = []]:

  generic reference coordinates of node; must be consistent with numberOfODE2Coordinates
• initialCoordinates [\({\mathbf{q}}\cIni = [q_0,\,\ldots,\,q_{nc}]\tp\cIni\), type = Vector, default = []]:

  initial displacement coordinates; must be consistent with numberOfODE2Coordinates
• initialCoordinates_t [\(\dot {\mathbf{q}}\cIni = [\dot q_0,\,\ldots,\,\dot q_{n_c}]\tp\cIni\), type = Vector, default = []]:

  initial velocity coordinates; must be consistent with numberOfODE2Coordinates
• numberOfODE2Coordinates [\(n_c\), type = PInt, default = 0]:

  number of generic ODE2 coordinates
• visualization [type = VNodeGenericODE2]:

  parameters for visualization of item

The item VNodeGenericODE2 has the following parameters:

• show [type = Bool, default = False]:

  set true, if item is shown in visualization and false if it is not shown
