Comprehensive Cardiovascular Device Simulation Data and Process Management
Cardiovascular related simulations such as nonlinear finite-element analysis and computational fluid dynamics (CFD) generate very large data sets of results. This data needs to be tracked and managed, especially when multiple mesh refinements and material changes are performed on each model such as the stent shown in Figure 1.
If alternate designs need to be explored, then it results in many sets of files generated during simulation. Design modifications and parametric studies magnify the volume of data as new simulation data are either used or generated for each computation.
Simulation data may include design models, model configurations, geometryfiles (CAD), FEM model files, results, design requirements, input & output documents, design validation documents, material properties, load cases, and test data. It may even include non-CAE type files such as documents, spreadsheets, Mathcad* or MATLAB* calculations, MS Outlook* message files, as well as any type of method or template file that generated the content for a computation (see the illustration in Figure 2).
If this huge volume of simulation data and the associated design history files are not tracked and managed effectively, then it results in unmanaged information chaos, resulting in poor knowledge sharing, inability to access and reuse prior results, ineffective communication, and process inefficiency within the company.

This figure shows specific sets of results and ways that they can be summarized and reviewed. SimManager dashboards or portals can be configured to provide specific views for project management and limited views for regulatory review and communication. There is tremendous potential for streamlining the regulatory submission and review process, resulting in significant time savings.
