[ASK] Kangaroo bending length distortion

Dear All,

Im doing with several research with kangaroo physic lately, i found there is length distortion in the bending force calculating process. i found that to achieve same length for every curve is by set bending strength to 0(zero) after set to above hundreds which mean disable bending force after the form is settle. but that method leaves some kink curves. same problems i found in more complex geometry such gridshell.

Is there anyone could give me a hints how to let line bended without having length distortion at final result?. i tried to bend my stainless steel ruler and it slightly doesnt has length distortion. Thanks.

Regards,

Azan
