Vtkpost is a conversion program, for Windows, which converts solution files of the freely available finite element solver CalculiX CCX into vtk version 2.0 format for viewing in the scientific visualization environment ParaView.

My euphoria on the topic of principal stresses was premature. I was so pleased to find that the eigenvalue method avoided all the EDividebyZero exceptions in certain test files that I didn't notice it raised a number of EAccessViolation exceptions in entirely different files. The solution was to put the two methods, eigenvalues and poly roots, in series, for version 1.3 of Vtkpost. My latest tests indicate that no nodes in the entire test file group escape from this treatment, (excepting files that fail conversion anyway).
Right after release of version 1.0 I learned it was tied to a .dll I was not aware of. Cutting this tie resulted in version 1.1. Shortly afterward I found I was able to do something I had wanted to do for some time: calculate principal stresses directly through eigenvalues rather than solve the cubic polynomial. This new method resulted in version 1.2. The eigenvalue route does not offer additional accuracy, but it does make it possible to calculate principal stresses for nodes which were not tractable before. For a concise explanation of the math dealing with principal stresses, see: http://www.complore.com/derivation-principal-stresses-and-stress-invariants So now I feel that Vtkpost is in better shape, and, surprisingly, is even a bit smaller!
