Fix for a NullReferenceException triggered after loading a project in some particular cases.
Fix for a System.IO.IOException when saving the application settings that occurred when several running instances were closed simmultaneously and every instance tried to write to the same configuration file (as a result of a shutdown/logoff for...
November 2020 will see the release of AHED as
commercial product. Accepting licence terms & conditions will be a
necessary step when launching the program. This current release will serve as the template for the commercial product so license terms & conditions appear for the first time here.
This will be one of the latest updates of the program under the current name. For months we have been
working on a new version of the application, with a new registered commercial name and that will run from its
own new domain name.
When the time comes, the...
Some unnecessary warnings are now suppressed. They were
shown during internal calculations of some values that later were not
used in subsequent steps of the calculation.
When certain fields were left empty, an exception
occurred. This issue has been fixed now and proper messages describing
New feature: Mixtures:
The new feature for Mixtures in HRS-AHED allows the user to
define mixtures of the following 48 compounds (initially, more to be
added in the future):
Acetone, Acetylene, Air, Ammonia, Aniline, Argon,Benzene, Butane,Carbon dioxide, Carbon monoxide,Decane, Ethane, Ethanol, Ethylene, Ethylene dichloride (EDC), Ethylene glycol,Helium, Heptane, Hexane, Hydrochloric...
The calculation of Baffles is not possible whenever an error happens in Geometry: The button 'Calculate' is disabled.
In some cases of incorrectly calculated geometries (or
with errors), tubes where shown outside of the shell (results from
previous valid calculations) or a drawing exceeding the expected limits
When Condensation processes are calculated, the inlet Vapour Fraction
is always set to 1 and the outlet is set to 0. The fluid's physical
properties in liquid phase are left
empty (not calculated) when the vapour fraction is 1
(there's no liquid phase). In the same way, when...
Due to the growing number of data that was being shown
in the Heat Balance page (fields for inlet/outlet, shell/tubes, fluid
data table, etc.), we have decided to simplify
this page and to move the fluid information to two
previous pages, exclusively dedicated to the selection of the...
Heat Balance: More fixes regarding the Fluid edition for
cases in which the unit system was not Metric. Molar Mass field was
always handled as Metric, regardless the unit system
used and for that reason there was not a correct unit conversion
for it. The constant used in the property...
Heat Balance: The last release had a bug that made that,
despite the user might change the measurement units of a project, the
fluid data tables (for both tubes and shell)
were not updated. This issue has been fixed. Now the change of
measurement units refreshes the data tables accordingly....
