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.

主要目的是扩展现有的数值框架并处理与时间有关的问题相关的复杂性。此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。要使数值模型更接近实际设备的物理，我们将包括粘弹性材料行为和接触层的粘合性交互。此外，为了计算快速电流电流，我们将结合耦合的PDE触发接触力学和静电的有限元模型与电路ode的时间溶剂。这些发展将由MOFEM [5]中的最先进的科学计算工具提供支持，从而实现了证明模型的预测能力所需的大量并行模拟。我们将使用格拉斯哥大学，Archie-West Super Computer Center和Cloud Resources的本地HPC设施进行这些研究。此外，该项目将包括与Teng进行实验研究的材料与制造研究小组的合作。因此，第二个目标是为TENG提供有效，可访问和可靠的工具，以帮助我们的合作者加速新设备的设计，优化和原型制作。我们将使用JupyterHub将整个仿真管道（设置模型，后处理，可视化）移至Web浏览器中，而计算将使用本地或云HPC功能在MOFEM中执行。
