post processor

I am new to the w2 model...I have been able to pre process and run the example models, but still haven't determined how to post process an .opt file...when the models are running, the array viewer displays for example temp, residence time and dissolved oxygen. How is this determined that only these three parameters are displayed?... and I assume that once I post process an .opt file, I can view results from other parameters. Also, do I post process any .opt file? Could someone shed some light on these topics for me? added March 28/03 - I was premature with posting only the above paragraph before reading through the forum completely...I see that the program does not have a post processor to display the results...any suggestions on an user friendly way to view output for a first time user of the model?[addsig]
