CAD-Centered Integration and Efficient Visualization of Multidisciplinary Simulation Data

Multidisciplinary simulations are becoming imperative for the design of complex products. However, it is not an easy task for designers to quickly view the simulation results. The reason is that the simulation data are usually too huge to be transferred quickly and they are heterogeneous and have to be visualized in specific tools. In this study, a novel CAD-centered method of seamless integration and efficient visualization of multidisciplinary heterogeneous simulation results is proposed based on the intermediate model. Here, a common simplified mesh model is used as the intermediate visualization model in CAD platform by analyzing different simulation requirements. The mapping association is established between the intermediate mesh and the simulation meshes of different disciplines based on relative coordinates. Based on the mapping association, an interpolation approach is proposed to achieve the simulation results for visualization in CAD platform. To accelerate the transmission speed, several strategies are deliberately devised: parallel mapping, parallel interpolation and incremental transmission. Several examples are provided to demonstrate the out performance of the proposed approach.
