Ansys Insight: Difference between ”Maximum Generations” and ”Generation size” in Optimization

      Please refer this article: Optimization utility
       
      Simply put,
      ”Generation size”  is the number of simulation files at each generation, like a flock of birds.
      ”Maximum Generations” is the maximum number of generations, like the number of destination of the flock of birds, in order to find the best places.
       
      The total number of simulations is equal to, or fewer than their products. Once the optimization target is realized, the optimiztion will stop. If it is not converge, more number of generation is required.
       
       
       
      ”Generation size” :每一代的仿真文件个数,每个仿真文件有不同的参数,就像一群鸟的数量。
      ”Maximum Generations”:最大的代数,就像这群鸟要找的实物最丰盛的目的地个数一样。 满足实现设置的优化条件,优化就结束了。如果结果并不收敛,可能需要增加代数。
       
      总的仿真文件数可能达到两者的乘积,因此所花的仿真时间可能比较长。
