Hi Roy, That property should show the moisture input. It is an output property, so it will only update after you simulate. Otherwise, it might be some other problem. If it persists, perhaps you can send us the model (or a portion of it), as well as the version number of the software you are using.

Hi Valentina, If you want the draw tool to follow the reference graphic, then make sure the yellow padlock button indicated below is activated. Also, open the menu under the button and make sure a tick appears next to References. I hope this helps. Let us know how you go.

Hi Roy, In the spreadsheet, the Airway Name property just shows the first line of the Airway Name. If the airway has a name, then that's the first line. If it doesn't, then it gets something else, like a Heat Preset, and makes that the name. If you want just the Heat Preset name in a property, you should see it here: Let us know if this clears it up for you and does/doesn't give you what you need.

Hi Roy, in Ventsim DESIGN 6.0.2.0, if you use the Data Display option in the Clone Options form, cloning airways will bring across the data boxes as well.

Hi Roy, this has been fixed in the just released Ventsim DESIGN 6.0.2.0. Thanks for bringing it to our attention.

Hi Michael, Firstly you should thoroughly check over your fan configuration and be confident it is modelled correctly. Do you have a measured flow rate as well? Is this measured duty point on the fan curve? Once you are confident of the fan set up, then the pressure difference would suggest that you are overshooting the network resistance of your mine. So you would have to investigate the model and try to determine where it might be that too much resistance is specified; this could be coming from e.g. airways sizes, friction factors, shock factors, regulator resistances.... A good place to start is the Audit Tool, which you can find in the Tools menu. Open this and it will run you through a few things to check in your model. It has a button which colours the model by an appropriate colour to investigate the question that each page asks. I would go through that first. Let us know how you go.

Hi Ruan, Firstly, click on the green plus button on the Levels tab of the Display Manager. Then either enter in your own levels, or click the magic wand to automatically generate levels. Then, you can right click in the viewer and select Clip Level. Click on an airway and the view will clip to the corresponding level. Or drag a fence to clip multiple levels. Page Up and Page Down will scroll through the levels. You can also just directly hit the Page Up or Page Down buttons and it will start scrolling through the levels starting from where your grid is currently focused. In all cases, hitting Show all (shortcut: End) will show all levels.

Thanks Roy, we weren't aware of this. It is detecting numerical noise when off. We can fix this for the next version.

Hi Roy, I'm pretty sure we can do this for the next version. We will get back to you.

Hi Roy, we've fixed this issue in the latest version of Ventsim DESIGN 6.0.1.9 which you can find here: Patches | Ventsim® Thank you for contacting us about this, any problems, let us know.

Hi Ruan, we've added this feature in the latest released version of Ventsim DESIGN 6.0.1.9, which you can find here: Patches | Ventsim® Thanks for the feedback!

Hi Mark, Sorry you've had this problem. This was a bug with an early version of Ventsim 6.0. If you go to the following link and download and install the latest version you will see the problem should go away. Patches | Ventsim® Let me know how you go.

Hi Haran, Go to your Visibility Manager and check that your transparency options are all on. If still happening, send us an email at ventsim.support@howden.com, either with a model, or some screenshots. Also go to Help | About and tell us which version of the software you are using.

Hi Roy, we've fixed this issue. Apologies. We will release a new version soon. I will post here again when it is available. Thanks for getting in touch.

Sounds like you need to activate the license Azli, or there is a problem with it. Send us an email at ventsim.support@howden.com with the details and we will sort out what is happening.
