Problem definition: A rectangle plate 200*300*3 alumnium material. Constraints: four surfaces (except the two biggest surfaces) are constrained in X/Y directions, set limited displacement at X/Y=0; Excitation:give fluctuation force excitation in Z direction on the four surface. Study: Eigenvalues，frequency domain. Response: Calculate the average velocity top surface respect to force in Z direction.
Process: Define an average on top surface in non-local coupling. set as name as av. Define a variable name as Sv with equation as 20*log10(av(abs(solid.uAmp_tZ)))
My question: 1.Is the expression right? 2.After mesh and study, the plot can only be seen under study1/sol1 but can not be seen in study1/store,is it reasonable?
Thanks
