Inputs for Large Structures

      Hi, I'm having trouble running a large structural simulation. Since large structures have many substructures, the input time to the simulation area is long.

      That is to say, the input speed of the first dozens of substructures is fast, and the latter dozens of substructures are getting slower and slower. (I don't know what happened to this)

      I also took several fsp files, combined into a complete structure. but using load For example: load('one.fsp'); load('two.fsp'); load('three.fsp')..... However, the latter will delete the former, with the result that only the structures created by the last fsp exist.

      Also: addjob and runjobs This is for simulation computing tasks and does not act on structural inputs.

      Hope you can give me some advice. I'm looking forward to your response.

      For loading and running several different files, I believe I have already replied and you agreed it works:

      /forum/forums/topic/about-loading-files-of-type-lsp/

      I do not understand why this same issue is raised 3 times. Once again, one GUI can only hold one simulaiton file.

      You CANNOT combine different simulaiton files into one to get a large device !! One simulation file is only for ONE device. You can only cascade the device with more than one sections along the propagation as shown in the example which I have sent you the link in another post.

      "addjob" and "runjobs" is to run a series of simulation files. it is NOT used to combime the substructures into a larger structure. 

      Please make sure this issue is resolved for you.

       

      As for the slowness of more substructures, it is normal since everything needs to be displayed through your computer with the display card capacity.  One alternative way to increase the display speed is, using "wireframe" instead of "detailed":

       

       

      If this does not help, you will need to upgrade your hardware with more display memory.

        Thank you so much, I'm sure I got it all.

        the last one

        using "wireframe" instead of "detailed":

        Does the accuracy of the displayed details affect the simulation results?

        Will it affect the simulation results? ? ?

      It is for display only.
