The flowchart begins at the top with a rectangle labeled “Start,” followed by a downward arrow leading to a rectangle labeled “Setup of sampling, responses, and variables.” A downward arrow leads to an oval labeled “Impact energy E, impactor initial velocity v, and weight m: E equals 1 over 2 m v squared.” A downward arrow leads to a rectangle labeled “Insert velocity value into dyna input file,” followed by another downward arrow leading to a rectangle labeled “Simulation case executing.” A downward arrow leads to a diamond decision box labeled “Sampling complete.” From the right side of the diamond, a rightward arrow labeled “No” loops upward and connects back to the right side of the oval, adjacent to vertical text reading “Derive another energy value.” From the bottom point of the diamond, a downward arrow labeled “Yes” leads to a rectangle labeled “Extract the response metrics from simulation results,” followed by a downward arrow leading to a rectangle labeled “Finish.”LS-OPT work flowchart of automatic virtual LVI testing campaign and database generation for ANN
