Functions

func Compare

func Compare(exp, act []hd.LoadCase, eps float64) error

Compare reactions and displacement, return nil is load cases are same or return error for other cases.

func LoadUniform

func LoadUniform(m *hd.Model, beamIndex int, projection bool, uf [2]float64) (ln []hd.LoadNode, err error)

LoadUniform - convert uniform load on single beam to node load and return slice of node load or error if input data not valid. Use for selfweight - not-projection load.

uf is uniform load in global system direction
[0] - X , Unit: N
[1] - Y , Unit: N

Example of projection uniform load on beam with different location:
uf = [2]float64{ 0.0 , -1.0 }

TODO (KI) : add specific for pin ends, because that function specific only for rigit ends.

func SplitBeam

func SplitBeam(m *hd.Model, beamIndex, amountIntermediatePoints int) (err error)

SplitBeam is split beam on small parts. Rules of splitting:

• beamIndex will beam connected to start beam point
• all new point add at the end of point list
• all new beam add at the end of beam list
