Adding additional solid layers above a roof surface

[tkc]

I am trying to create additional layers on top of a roof surface which i obtained from the tutorial model. Anyone has any idea on how should i go about doing it?

My idea is to obtain a temperature distribution of up to 10m above the roof by additional addition layers above the roof layer

Hi,

Do you mean you want to add rooms on top? To do that then just set your Plane Height (on Shape Settings when you start to draw in Plan view) to the height the roof is at and the rooms you draw will be placed ta that height.

Alternatively go into side view and you can draw in that perspective or copy rooms upwards if you wanted.

Hi Phil,

Yes i am intending to add rooms above the model as provided in the tutorial.

I trace/overlap the outline of the drawing based on the Plan view and gave it a height of 10m and plane as 0m. I didnt check the box for create inner volume.

Can i check if what i done is right? My main intention is actually to obtain the temperature at the areas above the roof surface of up to 10m. Hence i draw additional rooms above the roof to try and obtain the temperature there using mircoFlo

Hi,

To add the rooms above existing is easy enough. Just draw in Plan view and choose the Plane to be the height of the current roof (i.e. the height you want the base of the next room to start) and then the height to be as high as you want the additional room to be so if Plane is 4m and Height is 10m then you will be drawing a room with its base at 4m and it's top at 14m. You'll get the hang of that part quickly (if you don't then...).

In terms of what you are trying to assess in MicroFlo I'm not so sure. I think it was yourself via Tech Support who had asked about measuring the heat coming out of a roof for your academic project and we previously advised it wouldn't be possible using MicroFlo external cfd analysis ("MicroFlo external simulation is isothermal only and so cannot determine temperature distributions outside the building") so I guess you are now trying to assess this internally instead but please be aware of limitations of MicroFlo in this regard and be careful with any results you are able to achieve.

When you have an idea of the modelling aspect then you could consider posting further in the MicroFlo section of this forum to discuss this project and the problems you face.

Hi Phil,

Thanks for the help. Another question I like to enquire is that if I drew a total of 4 rooms, any possible ways I can make only 1 room visible in the model view II (the 3D version) only. I will have 1 room (opaque) as the base, with additional 3 rooms above the base room being set as transparent which I want them to be "invisible" in the model view II instead of showing up as solid surface.

to have a room(s) hidden in Model Viewer ll you can hide them in the workspace. To do this

1. Select the room(s) and then in the key-in field at top left of ModelIT workspace type vis=off and hit the Enter key

or

2. Untick them in the Rooms Browser (bottom left of the workspace)

You will see they are then hidden from the view in the ModelIT workspace and when you open Model Viewer ll they are not displayed either.

got it,thanks!
