We implement and test the algorithm on a class of high-dimensional free boundary PDEs in up to 200 dimensions. Which yeilds. So when we're doing Mesh Analysis, and we have a current source which is shared between two loops, we have to use the concept of super mesh in order to solve the problem, because if we don't, we're always going to have this problem of this, this two voltage drop across the current source that we can't solve for. An easier method of solving the above circuit is by using Mesh Current Analysis or Loop Analysis which is also sometimes called Maxwell´s Circulating Currents method. e, to create the FEA model. These are also common in Civil Engineering problems. For each one, we “imagine” a current circulating around it. Choose a reference node. Fundamentals 17 2.
