In this work, we describe the implementation of FLARE - a fully vectorized Matlabsolver based on the finite element method, FLARE is (mainly) dedicated to stationary and quasi-stationary electromagnetic problems. These latter can be expressed via both time-harmonic and unsteady formulations. In addition, FLARE allows one to obtain the time-response of linear problems using an inverse Laplace approach. We describe the implementation of the code, focusing on the most time-critical operations, such as the assembly of the global stiffness matrix and load array. We also discuss the development of an unsteady quasi-stationary solver, which we use as a validation and benchmark tool for the inverse Laplace solver. The two approaches are used to study the inductive component of AC interference caused by power lines in buried metallic pipelines.

Abstract
In this work, we describe the implementation of FLARE - a fully vectorized Matlabsolver based on the finite element method, FLARE is (mainly) dedicated to stationary and quasi-stationary electromagnetic problems. These latter can be expressed via both time-harmonic and unsteady formulations. In addition, FLARE allows one to obtain the time-response of linear problems using an inverse Laplace approach. We describe the implementation of the code, focusing on the most time-critical operations, such as the assembly of the global stiffness matrix and load array. We also discuss the development of an unsteady quasi-stationary solver, which we use as a validation and benchmark tool for the inverse Laplace solver. The two approaches are used to study the inductive component of AC interference caused by power lines in buried metallic pipelines.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
