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.

主要目标是扩展现有的数值框架，并处理与时间相关的问题的复杂性。该功能将允许模拟实际TENG并以前所未有的精度预测输出电流。为了使数值模型更接近实际设备的物理特性，我们将包括粘弹性材料行为和接触层的粘合相互作用。此外，为了计算短路电流，我们将联合收割机耦合PDE控制接触力学和静电学的有限元模型与电路ODE的时间求解器相结合。这些发展将得到MoFEM [5]中可用的尖端科学计算工具的支持，从而实现展示模型预测能力所需的大规模并行模拟。我们将使用格拉斯哥大学本地的高性能计算设施、ARCHIE-WeSt超级计算机中心和云资源来进行这些研究。此外，该项目还将包括与材料与制造研究小组正在进行TENG实验研究的同事合作。因此，第二个目标是为TENG的数值模拟提供一个高效，易用和可靠的工具，帮助我们的合作者加速新设备的设计，优化和原型设计。我们将使用MoneyterHub将整个仿真管道（模型的设置，后处理，可视化）移动到Web浏览器中，而计算将使用本地或云HPC功能在MoFEM中执行。
