the primary objective is to extend the existing numerical framework and handle complexities related to the time-dependent problem. This functionality will permit simulation of an actual TENG and predict output current with unprecedented accuracy.To bring the numerical model closer to the physics of an actual device, we will include viscoelastic material behaviour and adhesive interaction of contacting layers. Furthermore, to compute the shortcircuit current, we will combine the finite element model for coupled PDE governing contact mechanics and electrostatics with the time-solver for electric circuit ODE. These developments will be underpinned by cutting-edge scientific computing tools available in MoFEM [5], enabling massively parallel simulations required to demonstrate model's predictive capabilities. We will perform these studies using local HPC facilities at the University of Glasgow, ARCHIE-WeSt supercomputer centre and cloud resources.Moreover, the project will include collaboration with colleagues at the Materials & Manufacturing Research Group who are doing experimental research on TENG. Therefore, the second objective is to provide an efficient, accessible and reliable tool for numerical simulation of TENG, assisting our collaborators in accelerating the design, optimisation and prototyping of new devices. We will use JupyterHub to move the whole simulation pipeline (setting-up of the model, post-processing, visualisation) into a web browser, while computations will be performed in MoFEM using local or cloud HPC capabilities.
