Plate Thickness Optimization#
This example shows how to use PyDyna to import a mesh, set up a plate thickness optimization analysis, run the analysis iteratively until a target displacement is reached,and then display the results of that optimization.
Perform required imports#
Import required packages, including those for the keywords, deck, and solver.
import os
import pathlib
import shutil

)
# If you'd like to insert your own path to a local mesh file you can do so by replacing the line
# above with:
# mesh_file = "C:\Path\to\file\\bar_impact_mesh.k"
Set analysis parameters#
Define the number of iterations, thickness increment, target displacement, and initial velocity for the analysis
max_iterations = 20
initial_thickness = 0.1
thickness_increment = 0.05

Create a deck, which is the container for all the keywords. Then, create and append individual keywords to the deck.
