What is CAE Pre and Post Processing?

Simulation CAE pre/post processing is the working bench on which engineering knowledge, analysis solution tools (solvers), and CAD designs all converge.

CAE pre-processors are employed to correct geometries, proceed with discretizing it, apply loads and constraints, and define the properties of the model’s materials. Ultimately a ready-to-run file is generated to be imported into the solver for its calculation. Since pre-processing consumes the majority of work-time for a simulation analysis, automation tools and customization capabilities are very important in reducing the overall analyst workload. Managing the imported data from CAD systems is also a big part of pre-processing due to differences in modeling between CAE software as well as differences in data handling between CAD systems and simulation systems. Ultimately the mesh quality of the discretized model and the definition of the physical problem determine the accuracy of the analysis, while the levels of automation and the case-specific modeling tools determine the time required for the modeling process.

Post-processors import the result files from the solvers and provide the environments and the tools to create comprehensive reports through model visualization and charts. With a vast amount of data coming from the solver, the preprocessor should provide the required tools to select, control, and properly display the results, while also provide the required automation to reduce the duration of this time-consuming process.
