LineForceBase

Base model for line force elements

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

All line force elements should be based on this base model. This model defines frame_a and frame_b and computes the (guarded) relative distance s. An assertion is raised if the relative distance length became smaller as parameter s_small.

Parameters (3)

s_small	Value: 1e-10 Type: Distance (m) Description: Prevent zero-division if distance between frame_a and frame_b is zero
fixedRotationAtFrame_a	Value: false Type: Boolean Description: = true, if rotation frame_a.R is fixed (to directly connect line forces)
fixedRotationAtFrame_b	Value: false Type: Boolean Description: = true, if rotation frame_b.R is fixed (to directly connect line forces)
