Reading CSV files with magnitude/phase data with complex plot type

KrisGarner

Hi,

I am trying to read a CSV file that has frequency response curves as follows:

column 1: common frequency values

column 2: curve 1 magnitude values

column 3: curve 1 phase values (degrees)

column 4: curve 2 magnitude values

column 5: curve 2 phase values (degrees)

etc…

i.e. of the format X,Y1m,Y1p,Y2m,Y2p,….

However, Hypergraph does not seem to recognise this -even when reading in an Optistruct pch file, and writing out in the above format (albeit with the mag/phase columns switched around).

So, can it be done for a CSV file? I can read a pch file above and it automatically handles the mag/phase components. However, unfortunately, Hypergraph does not seem to be able to load multiple subcases from a pch file, so I don't seem to have a way to load multiple FRFs in complex format to then do some curve maths with.

Thanks,

Kristian
