NodeGenericODE1

A node containing a number of ODE1 variables; use e.g. linear state space systems. Note that referenceCoordinates and initialCoordinates must be initialized, because no default values exist.

The item NodeGenericODE1 with type = ‘GenericODE1’ has the following parameters:

• name [type = String, default = ‘’]:

  node’s unique name
• referenceCoordinates [\({\mathbf{y}}\cRef = [y_0,\,\ldots,\,y_{nc}]\tp\cRef\), type = Vector, default = []]:

  generic reference coordinates of node; must be consistent with numberOfODE1Coordinates
• initialCoordinates [\({\mathbf{y}}\cIni = [y_0,\,\ldots,\,y_{nc}]\tp\cIni\), type = Vector, default = []]:

  initial displacement coordinates; must be consistent with numberOfODE1Coordinates
• numberOfODE1Coordinates [\(n_c\), type = PInt, default = 0]:

  number of generic ODE1 coordinates
• visualization [type = VNodeGenericODE1]:

  parameters for visualization of item

The item VNodeGenericODE1 has the following parameters:

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

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