Problem with Calculation of the CMIF in Modal Analysis-Package

Hello Together,

currently i am stuck with the Modal-Analysis package.

Short Story: We did a modal analysis of a workpiece on the fixture and got result as we needed, all working fine.

After that we wanted to measure the workpiece, with the tool in contact to see the change in the resonances closer to machining conditions. For that i used the previous setup, added some nodes in the modal geometry and added the needed FRFs for them aswell.

So i just expanded the previous verision, where it worked as it should.

Having done the modal analysis, in the modal test ,i can see all the data in the Modal Test and the correct modal geoemtry movement at the selected Frequency.

--> Than moving to the Modal Analysis Setting, i add all the included FRF, i can see them in Preview and select orders and frequency tolerances for the stability plot.

When i move to the MA-Estimation to select the stabe poles in the stability Plot i does not work. I am pretty sure it is becuse the CMIF were not calculated, but i checked that all the inputs FRFs are there nad none are empty.

---> After hours of trying and basically doing the same thin over and over it worked. I have no clue why, but it is really annoying, especially because there is no feedback at all, what may went wrong or is missing.

Did anybody expierence the same problem?

Additionally a more basic but important question:

• i like to look at all the FRF stacked on each other. --> For this i need to select each and every FRF by Hand, which is (sorry for rough Speach) a pain in the ass to select 214 points at a time. --> How can i multiselect all the FRF or some gesture like Shift+LeftClick in Windows to select multiple channels or inputs for the same plot.
• The same issue for example if i want to view the FRF and its synthesized equivalent all have to be handselected --> all extremly annoying, prone to error, and time consuming.

Thanks for eventual input.

Best regards

Daniel

Dear Daniel,

thank you for reaching out to us. Would you please be so kind and send us a data file so that we can look at it. Please refer to our solution on How to send your files to Dewesoft team.

Regarding the stacking of the FRS's, sadly there is no multiple select.

Kind regards.
