<p>The cost of preparing analysis and data handling is remarkable compared with the speedup from parallelization. Several studies have reported for a problem solving environment (PSE) or a cloud computer aided engineering (CAE) service. However, few studies have covered part of CAE process. This paper proposes design of cloud CAE platform and development of a web-based all-in-one CAE system. The platform design takes account of applying to large-scale analyses by imaging methods and data structures. Assembling them, we provide cloud CAE services. As numerical examples, we apply the system to some finite element analysis models. We confirmed that this system has ability for CAE work which has a hundred million degrees of freedom.</p>
