ISTVectorPostProcessor
I wrote a Windows tool for postprocessing finite-element results: figures, animations, and reproducible scenes from EnSight Gold, VTK, and STL files.
Everything it draws is vector-based — contours, Gouraud shading, PDF export included. No bitmaps on sight. No GL2PS either!
Multi-step transient analyses, tensor fields, and symmetry replication are supported.
Free, self-contained, documented:
