Framework: ANALYZER

 Versatile Postprocessor & Analyzing Tool Set

Postprocessing in Sim4Life provides complete insight into intricate simulation results and measurement and imaging data through advanced visualization and analysis capabilities. Viewers tailored for medtech simulations (e.g., volume rendering, streamlines, maximum intensity projection, surface fields on arbitrary 3D structures) and calculators for recurring tasks (resampling, filtering, functional evaluation) on unstructured/structured field data are included.

Streamline view of H-field produced by the loaded MRI gradient coil      (1 MHz).

A novel pipeline architecture allows for the setup of complex analysis sequences and simple reevaluations with modified input data or parameters. Analysis steps can be stored in and re-loaded from analysis or visualization “projects”.

Processing (interpolation, interactive cropping/masking, etc.) and visualization of the simulation results together with the measured/imaging data directly on the models.

Derived quantities based on any solver results or measurement data can be computed and visualized by maximally exploiting the algorithmic and visualization capabilities of the VTK, including interpolation, DFT, and a generic calculator.
