Software for test-analysis correlation
Software for test-analysis correlation
(OP)
I am comparing vibration tests with FE results (Femap + Nastran) and would like to know which software (preferrably free) does the following:
* Overlay plot of test and FE FRF (should be easy)
* Manipulation of data, e.g. multiply, divide...
* Presents the test damping
* Modal correlation/MAC
* Simulated notching?
I had a look at SDTools and seems to do what I want, but looks like it is an add-on for Matlab. Dynaworks looks capable as well. Are there any alternatives?
Thank you all.

Not exactly freeware nor cheep, but some call it state of the art of validating/correlating/updating FE models from measurement data.

Would recommend LMS virtual lab correlation module.
It has three sub-modules
1) pre-test : To recommend better accelerometer/excitation locations based on the FE data
2) Correlation: Comparison of Test and FE results in terms of MAC/FRAC
3) sensitivity analysis and model refinement: Refinement of FE model.

Basically the first 4 requirements are fairly trivial, if you can afford a canned solution then go with that, but you really are paying a lot for a little.
It'll be interesting to see how you go with MAC, it never was worth a damn in my field.
