    the preceding steps are, 1-initial, 2-General static (to apply the gravity ) 3-Frequency (linear perturbation for modal anlysis). 4-Dynamic Implicit (to apply the acceleration) both models are totally linear, NLgeom is off always. can you write you email address to share the cae.

    Applying seismic excitation

    FEA way, Thank you so much for your response, actually the two models are identical apart form the step type. I have applied the Boundary conditions as shown in the photos. in short, for the model with the step of implicit dynamic, I disactivate the Boundary conditions for the step of implicit...

    Applying seismic excitation

    Hello Everyone, I am using ABAQUS to Apply a seismic excitation on a cylindrical structure (silo), the thing is that, I run two dynamic analysis for this cylindrical structure, 1- the first analysis is with modal dynamic step. 2- the second analysis is with Implicit dynamic step. in both...
