Version 7.60 will have FULL dynamic streamer loading with breakout 
voltage inputs and even ground strike distances and ground strike 
modeling :-)))))

There is always power in the "streamer load" even before breakout or 
there would not be energy heating the, yet to be created, streamer 
channel.  Not realizing that was always the problem with dynamic 
streamer load before.  I will probably have to write another paper on 
how my dynamic load model works...

Good idea ;-))  I actually open and close the files all the time 
too...  I "good" programmer could probably fix a lot of my 
mistakes...  Just "getting it to work at all" is my goal ;-))  I 
usually print files "all the time" for debugging in case it crashes.

Yes.  You could run Csec = 10 to 20 in one program and have another 
program running Csec = 21 to 30.

Yes,  The dynamic streamer loading in version 7.50 is not very good 
yet.  You need a minimum Cload or the streamers don't start 
right.  The new version will fix that.  Version 7.50 had the program 
set up for dynamic streamer loading but it was waiting on those 
models to become available.  I guess mine got here first now.  I 
think there is also a problem where the model keeps running "forever" 
in V7.50 with dynamic streamer loading.  I have been working hard on 
these problems!!

I hope to have the new version out in a day.

Cheers,

        Terry
