    Sir, thank you very much from INDIA.
    This is an extremely helpful video for me. Sir, your elaboration style is outstanding. Every point in the video was clear to me.

      @@PrasannaRoutray97 If the phase is wrapped, I would do that in MATLAB. I do not thrust COMSOL when it comes to additional calculations. If uses its own syntax and variable names that can be confusing. I usually export everything to MATLAB and I do things from there.

    thank you for this jobs my dear .yout tuto is perfect.however,i like to ask one question.in your tuto you using frequency when is 10 to show how the amplitude is looking.now my question how to make graph when frequency is 10 foe exemple.thank you

      Hi Christian, Unfortunately, I do not have the COMSOL license anymore, and consequently, I cannot look into this problem anymore... Sorry about that. Aleksnadar Haber

    Can i do it using FSI to generate the load over the solid and then use that load to determine the frequency response as a vibration spectrum?

    • @aleksandarhaber
      @aleksandarhaber  2 роки тому +1

      @@danielmateovargas3796 You can definitely define the load over the solid that will vibrate. Then, you need to couple structural mechanics simulations with other COMSOL modules (fluid-structure interaction). So, in principle, I think that you can do it. However, the problem you are considering is probably highly nonlinear. So, the results will only be valid around a linearization point (that is probably defined by the constant force around which the oscillations are defined). Best, A. Haber
