Abstract

Owing to the often unintuitive nature of numerical code for non-experts, a graphical tool is implemented harnessing the capabilities of node-based software, regularly employed with great success in computer graphics tools, providing the grounds for both expert and non-expert users for development of novel or iterations of existing algorithms. Alongside the developed program, a test is performed by simulating a 2D slice of the magnetic field from a 2D current source is performed, accompanied with the latter's reconstruction by the use of direct methods and optimization algorithms consisting in Gradient Descent (GD) and Non-Linear Conjugate Gradient (NLCG) methods, where an analysis is carried out on the performance of the differing methods and available options, the latter of which proving to be consistently superior to the problem at hand.
