How to get cable force when actuated with displacement?

[qpding]

TL;DR

Is there a way to get the cable force (tension) when valueType="displacement" in a CableConstraint object?

Description

I'm doing a simulation on a cable-driven elastic object. Defined the elastic object with ElasticMaterialObject from stlib3.physics.deformable, and the cable using

from softrobots.actuators import PullingCable
...
cable_t = PullingCable(eobject,
        name="PullingCableTop",
        cableGeometry=loadPointListFromFile(cable_point_list),
        pullPointLocation=[length, y, 0.0],
        translation=[0.0, y, 0.0],
        rotation=[0.0, 0.0, 0.0])

Read the doc from here and figured out that either force or displacement can be solved. I'm wondering if there exists a way to actuate the elastomer with cable displacement, and get the solved cable tension force at the same time, sort of like a force sensor?

Solution?

Tried this and got output:

print(self.cable_t.CableConstraint.force.value)

Can someone confirm if this is correct?

Yes it is correct. You can access the read only data fields force and displacement to get the actual/current value of both, either your input is a force or displacement.
