Dear all,
I've just started using IES-VE MicroFlow for CFD simulation. After I
complete the simulation there is only a program to visualize the result. *I
wonder how can I export the result as an ASCII or Text file?*
Thanks in Advance,
Mostapha Sadeghipour
PS: I'm not sure if there is a separate list for IES-VE users. Let me know
if I should post it somewhere else.
Why do you want to export in text format?

Chris,
First of all I want to save different simulation results for different
scenarios. Then I want to use other visualisation tools (e.g. Tecplot) for
my presentation. If there be another way to export the result it's still OK.
Thanks,
Mostapha
You can save the results file under a different name for each simulation.
I'm not sure the results file is compatable with any other tools. You should
contact IES to confirm that.
The CFD tool in IES is a simplified, dumbed-down tool which is not suitable
for large domains and only performs steady-state analysis not transient. It
is sometimes difficult to achieve convergence unless the model has been set
up very well.

G'Day,
you cannot - and I'm not sure why you'd expect to be able to? what you can
do though is save the entire project and ship that around, of course it's
only openable in IES. You can also create images etc.
what exactly are you trying to do?
Norm
That's right! Actually I've already saved my files in this way (*.CDF). But
I can not load the result back to the model! When I load these files in the
MicroFlo Visualization, it shows nothing but the basic geometry.
As far as I tried it's not compatible at all! :)
Thanks,
Mostapha
Ah, of course you can save each individual run so that you don't need to
repeat the simulation.
Norm
HI Mostapha,
I do not think txt or ASCII can be exported by Microflo. However, VE can
export .cdf file. Bear in mind, the cdf file is encoded and therefore it is
not so friendly to be used by other program. I've heard that the format
could not be imported into Ecotect successfully due to the grid matching
issue. No harm to try, however, in your visualisation tools if it can import
.cdf.
If you are going to save different scenarios or export visible results
(either in picture or video format), VE can do it directly without exporting
any file actually.
Cheers,

Good afternoon,
I think it's reasonable to be able to export the simulation result (whatever
it is) in a text file. In the simplest case what I want to do is to use the
numbers instead of images to analyze the result and I want to use another
software instead of IES-VE.
Thanks,
Mostapha
Hi,
interesting. what do you expect the file to look like? a 3-D grid of
locations with properties such as temp, air flow rate, humidity etc? what
resolution? Seems a nice idea but very far fetched at present. Like you'd
need some sort of standard or at least an agreement on formatting. Don't
hold your breath :)
You can open any previous .cfd file in the Microflo viewer by clicking on
file and open. works for me!

Not as complicated as you said. Just think of NIST FDS or Fluent result
files. There is some geometry/grid/results file and you can import them to
TecPlot. Sounds reasonable for me! Isn't it? :)
Mostapha
Well...
1. It is possible to export simulation result, but not in text format. Does
your 3rd party tool ask for txt?
2. It is possible to see numbers by using Cell Monitors in Microflo if you
define them in advance
Cheney
Thanks Cheney! Good point to start...
Reasonable and likely are two different thing unfortunately.
why don't you ping IES Support (PAlly or David Geddes are very good). you
could also post on the IES forum (not the linkedinone, that's just
marketing) - you get to it from the help menu pulldown in VE-PRO
good luck - let me know if you get anywhere :)
Norm
Thanks Norm. I'll do it for sure and let everybody know! ;)
Mostapha
I think you have gotten some help on this issue already but

It is very important that any tool or service allows you to get your
data back out of it - i.e. it is not a one-way street allowing
data/model entry but not extraction.
Ideally open standards exist for such interchange, but if not some
simple table-based data dump is infinitely better than nothing.
Documentation of the tool's own file format is another way to achieve
interoperability.
I try very hard to avoid using tools where I have no way to get my
data back out. My experience of the building simulation area is
limited to date, but so far my impression is that the current
situation can best be described as 'poor' on this front.
Mostapha is quite right to expect some kind of open data export.
Wouldn't it be nice to live in a world where we could easily shift
data back and forth between different modelling tools?
Wookey
Wookey,
it is not an accurate statement to say that "the current situation can best
be described as poor on this front". Every simulation tool I use has a
feature where detailed reports on the input data are available.
Regards,
Chris

There is a recognised exchange format that is acknowledged in commercial
CFD packages and post processors. It is CGNS. Unfortunately I have not
seen reference to it in building simulation CFD packages.
