Simulation-based numerical optimization of arc welding process for reduced distortion in welded structures
This paper presents an effective numerical approach for welding process
parameter optimization to minimize weld-induced distortion in
structures. A numerical optimization framework based on coupled Genetic
Algorithm (GA) and Finite Element Analysis (FEA) is developed and
implemented for a low and a high fidelity model. Classical weakly
coupled thermo-mechanical analysis with thermo-elasto-plastic
assumptions is carried out for distortion prediction of numerical
models. The search for optimum process parameters is executed by direct
integration of numerical models and GA-based optimization technique. The
developed framework automatically inserts the process parameters into
the simulation models, executes the FE-based welding simulations and

Finite element software with analytical sensitivity analysis

As structural optimization can be, of course, greatly sped up with the use of analytical sensitivies (analytical gradients) of the e.g. stress with respect to geometrical design variables, I wanted to inquire which FE software has the functionality. The ones I am aware of: NASTRAN can and ANSYS cannot. How about others?
Many thanks in advance!
