Using Large-Scale DSO on managed cluster to generate dispersion diagrams using Eigenmode solvers

      I am interested in using LS-DSO to compute dispersion curves for a variety of material and dimensional parameters. Is it possible to have a single "variation" include the parametric sweep of the relative phase between a master/slave boundary? I would prefer to export the data in a 2D report that was the phase vs the eigemode frequencies. This would occur over different variations of material property (parameterized as a project variable) and dimensional parameters.

      Hello,


      Which Ansys tool are you using? How would you like to use the tool? Could you please elaborate on this?


      Thank you.

      Karthik,


       


      we are using AnsysEDT, version 20.1 (most recent). As I understand this, I have two options to generate parameterized dispersion curves of structures with various material properties and dimensional parameters.


       


      (1) I can use the -batchextract exporteigenmodes flags to export the individual eigenmode frequency and Q for each material, dimensional, and master/slave frequency parameters. I can post-process the resultant data files to generate the dispersion curves, which could be fairly cumbersome. This may, however, be the only way to do what I want. If this is the case, I would like to understand how to use LS-DSO capability with the project to maximally leverage my available solver nodes. 


       


      (2) I would prefer to distribute parametric sweeps of material properties and dimensional parameters, with each "design point" sweeping the phase difference between the master/slave boundaries. In this case, I would like to simply export the results 2D report (of the dispersion curves) for each set of dimensional and material parameters. Again, in this case, I would like to understand the most effective way of distributing the solve across a cluster.


       


      Thank you. 


       


      Regards.
