Fast visualization of finite element analysis results using multiresolution meshes

This paper presents a new method for fast visualization of finite element analysis results using multiresolution meshes. The original mesh of a finite element model is coarsened and simplified to quickly visualize finite element results, and the simplified coarse mesh is overlaid with the original mesh in local regions of high stress gradients. Local regions of high stress gradients are efficiently detected by using pre-computed weights for shape function derivatives of finite elements. A parallelization scheme is applied to further accelerate the visualization speed of finite element analysis results. Numerical results show that the present method can be appliable to fast visualization of finite element analysis results in real-time simulations.
