[문제]
단자유도계(SDOF)의 질량하중 가진 진동수영역(정상상태) 해석을 수행하라.
.단위: m, kg(자중은 무시), N
.SDOF: m = 2 kg, c = 1 N.s/m, k = 4 N/m

(1) Part
.mass의 point를 지정 

(2) Property
.mass에 inertia를 할당

(3) Assembly
.part를 instance(실체)로 작성
 

(4) Step
.Step-1: Linear perturbation : Steady-state dynamics, Direct : nfreq = 3

.Field Output: 

(5) Interaction
.Spring, Dashpot 

(6) Load

.Load: Concentrated force
