Reduced method modal analysis

[alexchr]

Could anyone help me how after performing a reduced method modal analysis we can see results such as participation factors and mass distribution percentages for each mode extracted in GUI steps?

Hi,
what you are asking is very well "hidden" in Ansys. It is written in the Output window. Here's the bad news... But the good news is, you can redirect the output to a file:
/OUTPUT,filename,extension,<append>
where the <append> option decides if the file is overwritten each time a new run occur, or if the results are appended to the existing ones.
In order to re-direct the output to the window again (and stop writing into the file), simply issue
/OUTPUT,
this will get back to the defaults.

Thanks Cbrn,

You are right, some simple things are very well hidden with no reason.

By the time, after performing a modal analysis and try to apply an acceleration vs period SP spectrum i get no results.

Could you write (if you have used it) in single steps in GUI command just the procedure?

Although I read manual very carefully and the examples i can't manage it

Hi,
I did spectrum analyses several times, but exactly with the procedure described in the manual, so right now I can't help you on why you can't achieve it...
Perhaps need some more info about what exactly is going wrong.
