Among other options, radiotherapy plays an increasing role for the treatment of lung cancer. This has raised the need for strategies to compensate for respiratory motion of the target. Sophisticated techniques such as tracking of the tumour position have become feasible. However, calculations for adequate dose delivery to moving targets with maximum preservation of healthy tissue require unders...

In this work, we are interested in obtaining existence, uniqueness of the solution and an approximate numerical solution for the model of linear thermoelasticity with moving boundary. We apply finite element method with finite difference for evolution in time to obtain an approximate numerical solution. Some numerical experiments were presented to show the moving boundary’s effects for problems...

The computation of wakefield induced by an ultra-short charged particle beam is one of the most computationally challenging problems in high-performance computing for accelerator. With SciDAC collaborations in computational science, a novel moving-window technique is developed for the finite element time domain (FETD) code T3P to tackle this problem through the reduction of computing needs. The...
