Abstract
We designed integrated computer-aided engineering (CAE) middleware with a CAE solution for modeling and simulation work to reduce the cost and time of product development. This middleware automates an open-source-based pre/post-processor and solver simultaneously. We construct an open-source task scheduler to perform multiple tasks by using integrated CAE middleware in a heterogeneous cluster computing environment, and to conduct several simulations simultaneously. We also propose a data analyzer to obtain a suitable mesh model for efficient product simulation. The analyzer repeats the analysis with progressively-reduced mesh size until the change of the product displacement value becomes less than 0.1%; then, the mesh size is judged to be optimal, and the analysis result is judged to be accurate. Simulation of a cantilever beam matched the analytical results; this agreement verifies that the middleware is reliable.
