Unread postAuthor: JDP12 » Wed Apr 23, 2008 9:47 pm

k when i enter measurements for volume (plus i think you should just be able to enter the volume) i get a different answer than what i get on my calc.

i'm trying to do a coax gun in it, and thus found the volume of the actual chamber space to be 97.2 inches. then i divided this by pi, then divided it by r2 of 4" pipe. and it says it should be 7.7 inches long, and this checks out. but when i run these exact same calculations in GGDT, it comes out with 25. something cubic inches... am i just way too tired right now or is GGDT messed up??

ALSO, how can you try and portray a coaxial gun in GGDT? would you just run it like a barrel sealing gun?

Thanks

Well, I don't know if you're an idiot or not, but right there you've shown that you don't know how to read the fracking manual. Hint: You CAN just enter the volume if you RTFM and CONFIGURE the simulation accordingly.

Can we see a screen capture?

RTFM.

coaxial's are barrel sealing guns, for coaxial's you put the barrel diam in the inner diam section of the chamber data bit and it takes the barrel volume out of the chamber volume for you.

woops.... forgot about the manual, i had the manual saved on my desktop then i transferred GGDT to my flash and just the exe file is on it for space reasons... sorry guys..

and i thought when it said outer diameter and inner, i thought that that was of the pipe of your chamber... i didn't realize it was for a coaxial, sorry. so then for a normal gun would you just enter the outer diameter and then nothing else? Sorry for asking but right now i am at school and it doesn't let me run GGDT so i cannot look at the program right now, sorry
