Simulate a fiber fillament that is fixed on one side and under gravity stress?

Simulate a fiber fillament that is fixed on one side and under gravity stress?

Simulate a fiber fillament that is fixed on one side and under gravity stress?

(OP)
Hello Everyone,

I am trying to simulate a fiber filament (with a diameter 1,5E-5 m and 0.5 m long) under gravity. It supposed to be a really simple one and is thought to be a precondition for step 2 (which has "dynamic, temp-disp, explicit" step procedure).The purpose is the fiber that being fixed on one side, should be leaning on the floor before step 2 starts.

Because of the step 2, I could only use "dynamic, explicit" step procedure for step 1. I assigned the fiber as a beam element, but it won't work because abaqus/explicit 6.13 doesn't support anisotropic elasticity with truss, rebar, pipe, and beam elements (see the manual "22.2.1 linear elastic behavior").

I have also tried using "engineering constant" elasticity and beam method, but the following error occured: "Anisotropic material properties without a local orientation system have been defined for 10 elements." Even after I defined the material orientation (in module property), the same error still occurs. The problem still persists even using a truss element. I attach as well my input file.

Could anyone advise me how to simulate a fiber fillament that being attached on one side and is under gravity stress?

It has to be with step "dynamic, explicit" step. I could simulate the same simulation using "static, general" step method, but unfortunately this step method doesn't compatible with the step 2 (dynamic, temp-disp, explicit).

Thank you for any suggestion smile

Best regards

Gunardilin
