Grid computing technology is a focused field in high performance computing. This paper describes an engineering computation oriented visual grid framework VGrid, which is capable to bridge the gap between currently deployed grid services and the computational applications. Based on the Globus toolkit, and coupled with a client component, a services pool and a server component, VGrid visually performs resource discovery, task schedule, and result processing. VGrid improves the efficiency of utilization of resources by introducing a logical resource concept. VGrid applications of numerical simulations in engineering sciences are demonstrated.
