hi,
I downloaded this programme a few months ago but I forgot to install it... today when I was looking for some file on my computer I realized that I forgot to try it out...
lol stupid me - I've just tested it - and it's great


Basically, it's a pneumatic circuit simulation... you can build almost any pneumatic diagram you want to...

it uses pneumatic symbols to build circuits, in case you are not familiarised with them each symbol is described in layman terms, there are even schematics showing how each part works and help function really works as it should

you can create a pneumatic circuit comprising of an air source, then you can add a couple of valves, air cylinders, QEVs and much more... there are also a lot of electronic elements available...

then you can start the simulation and it actually works... you can see that valves switch, air cylinders extend etc.

everything is fully adjustable and the best thing is that this is a demo version

what do you think guys ??

EDIT
link to english version added

yeah its pretty cool. i downloaded something like this but i couldn't get it to work.
is there a visual simulator ? like the one that Antonio uses i think his might just be animation

simulation is visualised via the diagram itself

full version has a lot educational materials, videos etc. but even the demo version has every component described

It's pretty advanced... probably more than I need really..
I am not saying that it's difficult to use - in fact it's really simple to use...

but it's for real pneumatics so it's not a program designed for spudders... you can tinker with it if you want to use DCV valves, air cylinders and other pneumatic elements to design and build: a timer circuit that I built a few days ago; or a circuit that automatically meters fuel, ignites the mix and then vents the chamber; or just anything else

there in one pretty annoying restriction in the demo... you can't adjust flow control valves... but that's not such a big deal as you can adjust the inbuilt flow control valves on time delay valves

well i downloaded it, and its in sum strange language lol

its in some strange language lol
lol sorry, I don't remember where I downloaded it so I posted a link to version 3.6 but I just realized that you can download only korean and italian lg version...

but there is English version of fluidsim 4... I edited the link in my first thread... now you can download there english version

lol ok, ill download it later when i get on the laptop

Ah nice. Now I can replace my korean one with an english one.


EDIT:
What the flip man! It only goes up to 20 bar.
Pfft.

the version I have (3.6) can use up to 20 Mpa...
not that I think it's needed though.. you might have serious problems finding valves with working pressure higher than 300 psi...

besides I think that the future HPA spudguns would operate more less like the design I proposed a couple of months ago in tech's thread...
you know I am talking about the one that combines QDV with an air cylinder...

I don't think there is any point in pressurising controlling circuit to 1000 psi or so... all you need is HPA in the main chamber and air for the circuit contolling the air cylinder (which opens the main valve) can be regged dwon to standard pressures... in this way you one could use quite a lot of off the shelf parts

velocity has mentioned that his newest spudgun operates more less on this principle... I can't wait to see it


I've checked the newer version of fluidsim (the one in my link in the first post here)
and I've got to say that it's even better... there are almost no restrictions and more parts

I won't have problems machining them though...

there are valves for hydraulics that are rated to 3000 psi - it seems that they are worth trying out one day

but generally speaking it would be better to pressurise just the main chamber and the main valve with HPA... it would be cheaper and you would use less air for piloting
