StressRefine is a free and open-source p-adaptive finite element code designed to read finite element meshes and automatically extract more accurate stresses by performing higher-order analysis. It can also perform global-local (or “breakout”) analysis on large models by isolating a region of interesting, applying the displacements from the finite element results as boundary conditions on the interface between the breakout region and the rest of the model, and reanalyzing the local region with higher polynomial orders.
All the software and documentation is in a shared folder here.
The document are available in both office (word or powerpoint) and pdf format.
You can download all the docs in zip from in Office Documents.zip or Pdf Documents.zip, or download individual documents from the folder Office Documents or Pdf Documents
Documents include quick overview (readmefirst), description (StressRefine), user’s guide, theory manual, validation manual, and installation guide
StressRefine executable is a free version that works with Nastran model (.bdf or .dat) and ascii result files (.f06)
Download and run “stressRefineSetup.exe” to install the software. This installation file will create a folder stressRefine into which all executables and documentation will be installed..
Updated 2019 Version
Updated versions of the UI and analysis engine are available in the folder 2019Exe. After you have run stressRefineSetup.exe you can replace these executables in the stressRefine folder.
All the source for stressRefine is available in a github repository. There are two versions. If you are interested in the full functionality, but may want to make minor modifications, the more efficient version is recommended, which uses the projects fullEngine and fullUI. If you are interested in learning p-adaptivity or working it into your own code, the library version is recommended, which uses the projects SRwithMklProj, SRlibSimpleProj, and SRUiProj. This version is simplified to be more readable, but is less efficient for larger models.
