Description

Figure 1. Connection type FLOW-CONVERTER.

The FLOW-CONVERTER connection constrains the relative rotation between the two nodes about the third local direction, $e_{3}^{a}$ , to the material flow at node b, $Ψ_{b}$ . The constraint can be written as

u r_{3} = e_{3}^{a} \cdot (θ_{a} - θ_{b}) - β_{s} Ψ_{b} = 0,

where $θ_{a} - θ_{b}$ is the relative nodal rotation between node a andb and $β_{s}$ is a scaling factor specified as part of the associated connector section definition. By default, $β_{s} = 1.0$ . The local direction $e_{3}^{a}$ rotates with the nodal rotation at node a.

There are no available components of relative motion for this connection type; hence, kinetic behavior cannot be specified. However, the following kinematic quantities are available for output:

u r_{1} = e_{3}^{a} \cdot (θ_{a} - θ_{b}) and u r_{2} = Ψ_{b},

which will be output as CPR1 and CPR2, respectively.

The constraint moment is

\bar{m} = m_{3} e_{3}^{a} .

Limitation

At most two FLOW-CONVERTER connectors can share their second node where degree of freedom 10 is active.
