Causes:

You need to login into the Hysopt BIM Syncer to activate most of the buttons.

title	The volume (m³) of my space in Revit is zero or not calculated.

It is not possible to replace a base circuit ("CTRL-H") while Revit is highlighting an object. Instead you hear a Microsoft Windows sound.

This can e.g. happen when you click on a BC, while you are in the Sync Views mode.
Unfortunately this is a limitation of Revit. You just need to wait untill the highlighting is done, typically some seconds.

You can :

lower the higlight time in the settings page
Disable the Sync Views mode when replacing Base Circuits

title	What is the difference between Hysopt Optimiser and Hysopt BIM Syncer?

The best way to explain the difference between the Hysopt BIM Syncer and the Hysopt Optimiser, is to explain the common functionality and the specific differences they have.

Common

BIM Syncer

Optimiser

Both the Hysopt Optimiser as the Hysopt BIM Syncer share the functionality to:

Rapidly model P&ID schemes:

Fast P&ID modeler
BC methodology
Inspiration library
P&ID export to PDF and DXF
Digital Twin ready for calculation (use by Hysopt Optimiser)
…

Calculations:

System check
Propagation of power, flows and temperature regimes
Pipe selection

Specific BIM Syncer functionalities:

BIM & Hysopt model generation
Mapping
Validation
Synchronisation of system data
Synchronisation of building data
Synchronisation of calculation data from the Hysopt optimiser
Export P&ID & reports to Revit sheets
…

Specific Optimiser functionalities:

Optimise components
Simulation
Partial load analysis
Sensitivity analysis
Pareto Analysis
…

title	What if you change your Hysopt model or Revit model outside the Hysopt BIM Syncer

The changes will be detected when you re-validate.

Errors might occur when you removed some items. The mapping in the Hysopt BIM Syncer might think they still exist.

title	Which Revit components are taken into account by the Hysopt BIM Syncer?

title	How is a fitting (e.g. tee fitting) for which not all connectors are connected or a capped end handled?

Connector of tee fitting is not connected (disconnects)

In case of a disconnect, the BIM syncer will handle it as a fitting with two connectors, so it will not handle it as a Tee-point.

Info
In this case, the pipe segments primary and secondary from the T-point, will all be handled as ONE branch

Cap open end of tee fitting

Pipe is connected to tee fitting which is capped with a pipe cap
Tee fitting is connected with a pipe cap

BIM Syncer will handle that branch as a dead-end branch, and it will handle the fitting (from a hydraulic perspective) as a fitting with two connectors, so it will not handle it as a Tee-point.

Info
In this case, the pipe segments primary and secondary from the T-point, will all be handled as ONE branch

A non-capped pipe is connected

If a non-capped pipe is connected, then the BIM Syncer will handle it as a fitting with three connectors. It is assumed that this pipe is not fully modelled and needs additional pipe segments, fittings, and components.

Info
In this case, the pipe segments connected to the T-point will be handled as three different branches, seperated by the fitting

title	Revit and/or the Hysopt BIM Syncer crashes without any further notice

Solution:

Work through the following troubleshooting steps:

look into the log file and see if there is a message that helps you further.
look into the Windows Event viewer and see if there is a message that helps you further.
collect as much info as possible and contact your reseller. Check our support page.

Disable the Sync Views mode when replacing Base Circuits

If you enable the Sync Views mode, click on a Hysopt Base Circuit, and subsequently press CTRL-H to replace this Base Circuit, Revit sometimes intercepts the command to show annotations on the menubar. The Replace Base Circuit functionality of Hysopt is not loaded.

Image Removed

Unfortunately this is a Revit limitation that cannot be fixed.
However, there are some workarounds to avoid it :

don’t click too quickly on different hysopt Base Circuits
(give Revit the time to sync the view and highlight the Revit element before clicking on the next Base Circuit)

lower the higlight time in the settings page to 1 second

Can Hysopt BIM Syncer work with a central model when using Local collaborate or BIM collaborate?

Hysopt BIM syncer can work with a central model.

There are two situations:

Revit model is linked to a Hysopt model before central model creation
Revit model is not linked to a Hysopt model before central model creation

every user with a local copy is able to overwrite the Hysopt model.
