Describe the bug
The models contain springs of material *MAT_SPRING_NONLINEAR_ELASTIC, *MAT_SPRING_INELASTIC, *MAT_SPRING_GENERAL_NONLINEAR and *MAT_SPRING_ELASTIC with *SECTION_DISCRETE.
In the output files ..._0000.out the SPRING VOLUME and INERTIA is zero.
Sometimes the boundaries are not processed.
sp4.k
a) *MAT_SPRING_NONLINEAR_ELASTIC carry no load (IE is zero)
b) SPC force not equal to the spring force e.g. Node 31 has a force of -10, the spring 31 reports -200
sp4a.k springs are oriented in a general position in space. The reaction force is only in X-direction, e.g. Node 31 (-7.1, 0, 0)
To Reproduce
Run the attached models in a clean directory, watch the output for "IMPOSED VELOCITIES".
Evaluate the forces and energies from the TH file.
Expected behaviour
Volume and inertia should be not zero, see Comment 1 from SECTION_DISCRETE: This keyword maps to /PROP/TYPE8 (SPR_GENE) spring using a default mass 2.0e-03 kg and inertia 2e-02 kgmm depending on the units.
Each run should give the same results.
The springs should carry loads and should have the same force in the spring.
The springs should act when in a general position in space.
Output
A Comparison of a run with and without "IMPOSED VELOCITIES": diff.out.gz
