It is now possible to calculate multipass heat exchangers with mechanised headers, with any number of passes, even though this figure is not exactly divisible between the number of tubes. Now there might be a single orphan tube left, maximum. A warning is still being shown when the number of...

Fix in calculations using Baffles. In the last version, because of the introduction of the 'divide and conquer' algorithm, some of the Baffles calculations were left out the overall calculation. This issue has been fixed.Other minor bug fixes and improvements.

Annular Space Heat Exchangers restrictions: Only horizontal geometries are allowed. Only sensible heat calculations are allowed. The program will raise an error when trying to calculate any condensing scenario (either in tubes or in shell) or when trying to calculate a vertical geometry for this kind of heat exchanger. Important...

Fix in Pressure Drop calculations: when multipass heat exchangers were calculated, the module pressure drop for tubes-side was not calculated correctly.Other minor bug fixes and improvements.

Creation/Edition of groups has been enhanced.Trivial checks for non-null positive flow in Heat Balance are now done before the calculation of Duty.Unexpected halt condition when saving a Project with unnamed Fluids is now fixed.Incorrectly conversion of Specific heat values between SI and Metric is now fixed.Fixed an issue that allowed...

A new option has been added so that multiple processes and configurations can now be done within a single project file. This will be useful for more complex projects that might need heating/holding/cooling subprocesses or several alternatives to be offered to customer. This can now be done in a single...

New menu item Release Notes (under Options menu).No need to manually calculate Baffles when NO Baffles are used. This case is automatically handled from the Geometry calculation.Fixed a particular case in which LMTD was incorrectly calculated when both ∆T (at the Inlet and Outlet) were almost equal and there was...

New option in Geometry for roller-expanded tubes: When roller-expanded tubes are used, a different forced minimum tubepitch of 1.25 x Tubes outer diameter is used (instead of the regular 1.20 x).User can now change temperatures and flows from within the Overall calculation page, provided that those changes do not raise...

Translations: Some fixes/corrections and new messages.New menu item to calculate Temperature/Pressure for Water/Steam based on the free parameter (under Options menu).Fix in .NozzlesInletDensityPerSquaredVelocity and NozzlesOutletDensityPerSquaredVelocity (both for Shell and Tubes). They were wrongly calculated with the heat exchanger inlet speed, instead of using the nozzles inlet speedsFix for some NullReferenceExceptions...
