    DAPS4e.6

    A Fortran code for design and analysis of ring-stiffened shells

    DAPS4e.6 is an updated version of a Fortran code by John Renzi and William Gordon for design and analysis of monocoque and ring-stiffened circular cylindrical shells [DOI: 10.13140/RG.2.2.18176.92165]. The following failure modes are considered: • Shell stresses and displacements at mid-bay and ring-frames. • Axisymmetric collapse (AC). • Elastic and Inelastic Interbay Buckling. (EIB and IIB). • Elastic and Inelastic Monocoque Instability (EMI and IMI). • Ring-frame stress and Elastic Instability analysis (EFI). Solutions compare favorably with DTMB experimental results. DAPS4e.6’s IO is managed through a Visual Basic UserForm. Pre/post processing is done using macro-enabled Excel workbooks. The file DAPS4e.6.zip includes: • DAPS4e.6 executable and Fortran 95 source code. • Visual Basic UserForm and its 2022 Visual Basic project code. • Excel workbook pre/post processors. • Technical documentation

    Zgoubi is a raytracing code. Since 1972 it pushes charged particles through accelerators and beam lines, by stepwise solution of Lorentz force equation - and their spins via Thomas-BMT differential equation. Zgoubi simulates beam dynamics and polarization in a variety of accelerators (storage ring, synchrotron, cyclotron, betatron, microtron, FFAG, multi-pass ERL, etc) and optical systems (beam lines, magnetic and electrostatic optical components, time-of-flight and mass spectrometers, etc). The code includes built-in fitting procedures with a wide variety of constraints; stochastic SR energy loss; the tracking of synchrotron radiation (SR) Poynting vector; space charge models; various Monte Carlo procedures, etc. Contact: francoisgmeot@gmail.com Documentation (History of accelerators that zgoubi deals with, theory, tutorials): https://link.springer.com/book/10.1007/978-3-031-59979-8 https://link.springer.com/book/10.1007/978-3-031-16715-7, Chap. 14.

    HostDesigner

    General purpose de novo molecular design software

    Although many potential applications exist in chemistry and material science, software to allow the general application of de novo structure-based design methods in supramolecular chemistry was non-existent. To address this limitation we created HostDesigner, a code that builds and evaluates millions of molecules in minutes. This command line executable builds 3D molecular structures by covalently connecting user-defined input fragments with pre-computed hydrocarbon fragments from a library. The results are ranked with respect to desired geometric constraints defined by the user. See the User's Manual for further details including a list of literature citations for example applications. Download includes User's Manual, HostDesigner 4.3 source code (in Fortran), data files, example input, HDViewer executables for MacOS, Linux, and Windows, and mengine source code (in C). HostDesigner was developed and posted by author Dr. Benjamin P Hay
