2c. Define the maximum member size.

  1. In the Maximum Member Size box, type the maximum thickness of the trusses.This value should not be smaller than twice the length of the average element edge. Otherwise, the optimization process might create elements connected by only one or two nodes.

  2. Click OK.

How do I
  1. Select the manufacturing constraint type.
