monitoring boundary and engineering data

Lawrence · April 2, 2010, 21:25

Dear all,

I am using STAR-CD 4.12. I am working on transient simulation with some monitoring boundaries. Then after the case has been run successfully, I get the engineering data file *.erd.

But there are too many data points in this file. I think the data at every iteration have been recorded rather than every time step.

Could you please let me know how I can set the recording interval for the engineering data? It seems that it is recorded every iteration by default.

Thank you!

Lawrence

The erd file records every time step. You can not change it.

Thanks Pauli !

I would like to convert this data file into some other format like txt or excel. Is it possible? Because I usually use Matlab to process the data.

Use edgraph & edload to load the erd/ecd information into the graph registers. Then use sdata to write the graph registers to a text file.

Yes, you are right!

I have got the text files using your method.

Thanks.
