  3. Dual Number Automatic Differentiation

    05 Jun 2014 | Downloads | Contributor(s): Wenbin Yu, kshitiz swaroop

    DNAD (dual number automatic differentiation) is a simple, general-purpose tool to automatically differentiate Fortran codes written in modern Fortran (F90/ 95/2003) or legacy codes written in previous version of the Fortran language. It implements the forward mode of automatic differentiation...

  4. PreVABS

    16 Nov 2017 | Downloads | Contributor(s): Su Tian, Xin Liu, Haodong Du, Wenbin Yu

    PreVABS is a pre-processing tool for VABS and SwiftComp. This tool is designed to reduce the workload of preparing input files of beam cross sections for VABS and SwiftComp, and to make the process automatic for the design and optimization purpose. Cross sections with general and...

  5. Geometrically Exact Beam Theory

    11 Jul 2014 | Downloads | Contributor(s): Wenbin Yu, Qi Wang, Su Tian

    Geometrically Exact Beam Theory (GEBT), is a general-purpose tool for nonlinear analysis of composite slender structures, meeting the design challenges associated with future engineering systems featuring highly-flexible slender structures made of composites. GEBT is based on the mixed...

  6. PostGEBT

    15 Aug 2014 | Downloads | Contributor(s): Qi Wang

    PostGEBT is a post-processing code which can effectively visualize mass data generated by the nonlinear beam solver GEBT. PostGEBT reads and visualizes the results produced by GEBT for static, steady-state, transient dynamic, and eigenvalue analyses. More details can be found in the PostGEBT...
