Real-time finite element simulations on an arm microcontroller

Real time processing enables online reactions to dynamic environment changes. The author focuses on possibilities of implementing the Finite Element Method (FEM) to real time algorithms on microcontrollers. The paper presents the current state of the Real Time Finite Element Method (RTFEM) and describes results obtained by the author. The RTFEM for microcontrollers (with examples of use cases) is presented and results of the computations for the chosen platform are given. The results consider optimization of RTFEM computational algorithms for a microcontroller taking into account their execution time. All the tests were performed on the ARM-CortexM4F based STM32F429ZIT6 microcontroller. The obtained results were compared, discussed and presented in the paper.
