BOAT3D V4.52 -- the Digital
has a long-term commitment to provide simulation software with
5/28/16 --- For a long time DMSolver, EDTECH, and
Flash Calculator have had Win32hlp help files (BOAT3D still has a
traditional text manual). However, Microsoft for a long time has been
trying to deprecate Win32hlp and finally eliminated it in Windows 10,
so the 3 Win32hlp files have been converted to html (not exactly as
good but close). For now you have your choice of Win32hlp as before
or using your browser to read the new files.
In a recent development, the DMSolver installer
has been found to have had a bug for some time regarding the
interfacing with the Free Pascal compiler. I apologize for this.
Also, I have been having for some time a difficulty preparing the
object code for DMSolver, and when trying to upgrade to the latest
Lazarus/Free Pascal nothing would work. I tried the next-to-the last
version, and finally found the problem--an obscure syntax rule. So
now DMSolver needs a slightly older version, but I should be able to
upgrade to the latest soon. Meanwhile, you can download the older
version here. older news
Some Digital Analytics products:
--- DMSolver provides a
language and algorithm for simulation of large (or small) systems
described by nonlinear ordinary differential and/or nonlinear
algebraic equations. Version 6.02 is now available. DMSolver 6.0x is
about twice as fast as V5.x and has a simplified user interface,
including the interfaces needed to set up problems using its
parameter estimation add-ins.
EDTECH editor for
technical data and graphics also provides a utility that produces
graphical output from files produced by other Digital Analytics
programs. New version 3.73 fixes the drawing printer interface so you
can more easily use modern printers. 3.74 has a "freehand
drawing" mode which may be useful to some people.
--- BOAT3D application
developed orginally by the late P. R. Payne to simulate planing boats
with 3 degrees of freedom, uses DMSolver methodology which has been
upgraded recently to include some of the speedups in V6.0 DMSolver.
--- Flash Calculator
does vapor-liquid equilibrium calculations for chemical engineering.
--- Some other products are not currently
supported, but details about them have been left in the web pages
because new versions may be developed in the future.
