Amplification factors wind analysis

[st_george]

thank you for the reply Liam.
I really owe you a couple of beers mate.

[liamh]

No problem. You never know one day I might try to collect those beers

[st_george]

Mate I mean it.
In my country this is not just a "saying". When I say something I mean it.

Also, if you need any other kind of help, just let me know, ok? There is private message or email, here, just send me one, and I will help you if I can and know.

Liam.
To be quite honest I did not understand you the way I could calculate the velocity in those 10 points.

But I can calculate it in Solidworks, and then export both excel files, edit them into single one (to get the amplification factors) and then import it into MicroFlo to get the plot from those points.

Can you help me with that part? How should my Excel file`s structure look like, in order to be able to import it into the MicroFlo and get the plot from these points?


Sorry for inconvenience, and thank you once again.

Now you have me confused.

The way I suggested you do it was as you couldn't produce a contour slice image in Microflo you could just provide a table of values in your report rather than an image, e.g.

location reference | amplification factor
1 | 1.2
2 | 0.9

And then give an image in your report showing the location of 1, 2 etc.

You can't import data into Microflo from another CFD program to get Microflo to produce plots.

I then gave you a method how to find the velocity at certain points in a Microflo model just in case you decide to do the CFD in Microflo rather than Solidworks.

I can't tell you how to do it in Solidworks as I have never used it but it sounds like you can get the numerical data out to do a Amplification Factor calculation which you could also put into a table.

Now I am confused Liam.

I though I can get the results (velocity) for certain number of points in MicroFlo.
Do this for both cases - with and without the new building. Then export the data into 2 excel files. Then by dividing the values of velocities from these two excel files I would get amplification factors.
Then I would import back these amplification factors into MicroFlo, and get a 2d plot from it?

Q> I though I can get the results (velocity) for certain number of points in MicroFlo.

Yes.

But be aware that the numbers dumped to the location files in the "cell" subdirectory are the x-, y-, and z-components of velocity. So you will have to do a little more maths to find the velocity magnitude, i.e. the air speed.

(x-velocity^2 + y-velocity^2 + z-velocity^2)^0.5
= (numberFromColumm1^2 + numberFromColumm2^2 + numberFromColumm3^2)^0.5

In other words you:

1) find the numbers in the 1st 3 columns of the last line in each of the cell location files
2) square each of these numbers
3) sum the three resulting numbers from step (2)
4) take the square root of the sum from step (3)

Q> Do this for both cases - with and without the new building. Then export the data into 2 excel files. Then by dividing the values of velocities from these two excel files I would get amplification factors.

Yes.

Q> Then I would import back these amplification factors into MicroFlo, and get a 2d plot from it?

No. Microflo can't do this.

You cannot get Microflo to do **any** kind of plot of amplification factor, including a 2D slice contour plot if that is what you mean by a "2d plot". As you can't get Microflo to do a plot I suggested you put the amplification factor into a Table of values rather than rely on a plot.

If you don't understand what I mean you'd better give me your email address so I can contact you directly. If you click on the email button at the bottom of one of my posts you'll be able to send me an email with your contact details.

I see.

This is what I meant by "2d plot" (just instead of "Velocity" I want to get "Amplification factor"):



Then MicroFlo is not what I need. Because I can get the amplification factor for certain points in a excel table from Solidworks. I already got it, take a look:



What I fought, is that MicrFlo can now import this excel file, and then show me the "2d plot" of amplification factors. But now I understand MicroFlo can not do this. Solidworks also.

Sorry for all the mess and disturbance.
I know the topic, and all your explanations will be useful to somebody else, definitively.

You even offered me email contact, after all this explanations? I really do not know what to say. If I can anytime, help you with anything, just send me an email here, ok?
You never know when you will need it.
