Extract parameter from Model Analysis

[JCReynolds79]

Hello all.

I wish to extract a parameter from the results of a XSEC analysis and put it into another excel analysis, as an input cell.

Ordinarily this would be simply, creating the analysis feature with the right parameter enabled so I could then select this parameter to input into the excel analysis, but this isn't so straight forward...

When performing an XSEC analysis, the last result in the information window is the Section Moduli... it is one of these values that I wish to extract to a param, but when editing the analysis feature, it isn't one of the options to create a parameter for.

So my question boils down to, how do I extract that piece of information in a form that can be input into another feature, i.e. the excel analysis?

Many thanks in advance.

Hello again,

Just to try and simplify my question...

How do I create a parameter for Section Modulus?

or

How do I extract a piece of information from the results of a Model Analysis that appears in the Information Window?

Cheers!

John,

In ProE 2001 (qnd this shoul be similar in Wildfire versions), right click on the Anlaysis feature in your model tree and choose INFO. A new window will appear and at the end you will see the parameters holding the values of your analysis if you have chosen to create them during the analysis creation feature.

You can save this as TXT, edit the file, simplify it and you can import it in your EXCEL.

Hi Hora,

Thanks for your input, although that doesn't quite allow me to just create an excel analysis with one of the inputs being the result of the analysis feature I am trying to extract.

I have founda way round it now by using the moment area of inertia, which is a usable parameter and a distance analysis feature (representing Y) both of which I can calculate the section modulus from...automatically.

Works a treat now! automoated FFoS determination.

John, you can allwas add relations in Pro to use the analysis feature parameters to obtain what you need. Then export these values in Excel.

Ex:

IXX = INTERIA1:FID_ANALYSIS1


Good luck.

Yeah this is my point, there is no feature parameter for Section modulus.

When you do a Xsec analysis feature, in the info window it shows you lots of information, including the section modulus, but the section modulus is not one of the parameters you can enable in the feature analysis setup.

So its a bit annoying that it is going to the trouble of working it out, but not letting you use it as a parameter.

Cheers,

Jon

OK I see.

The parameters you can use in an analysis feature are:

XSEC_AREA
XSEC_INERTIA_1
XSEC_INERTIA_2
XSEC_XCG
XSEC_YCG
XSEC_IXX
XSEC_IYY
XSEC_IXY

Probably you some more shown in the info window. There will be a workaround as yiou said.

A workaround:

You'll have to derive the section modulus from measured values in the model. As I'm sure you are aware, the section modulus S is the moment of inertia divided by the distance of the extremity of the section to the centroid (in the direction you are interested in finding S for), so S = I/c.

You have I from your section analysis, now you need to make another analysis to find c. You might want to redefine X-sec analysis to create a point at the section's centroid, so that you have something to measure from for the second analysis.

Once that's done, you can create a new Relation analysis to calculate the section modulus. The syntax for the relation should be:

section_modulus = XSEC_IXX:FID_SECTION_ANALYSIS[/color blue] / DISTANCE:FID_DISTANCE_MEASURE[/color blue]

Where SECTION_ANALYSIS and DISTANCE_MEASURE are the feature names of the X-sec analysis and distance measurement, respectively. Clearly, this corresponds to the section modulus about the x-axis, so if you need multiple section moduli, you'll need to repeat the process for the measurement, but you should be able to lump all of the relation analyses into one feature.

The parameter section_modulus should then be available for your Excel analysis. A pain, I know, but it's the only way to get these values that I can think of. You should also contact PTC when you get the chance and file an improvement request..

Hope it works out!

oops.. It seems I scrolled too quickly when reading through the thread.. You've already solved the problem!

justkeepgiviner,

Thanks for your thorough answer, but yes, this is exactly how I worked around it.

Seems a pain that it works it out but then you can't directly use it.

Thanks anyway!
