EnSight Standard is a general purpose visualization and post-processing tool for CFD, FEA, FSI, and other meshed 3D data. EnSight is unique for its ability to load results from as many as 16 runs at one time, large, transient models, and mixing different solvers to allow for comparisons. Also unique in outputing results in many 3D formats like EnLiten, STL, VRML, JT, and coming soon 3D PDF.
Image and movie quality, and realistic results via ray-tracking, textures, and antialiasing are other reasons EnSight is the BMW of post-processors.
