Improvements to water

[thebeech]

I believe that the water on algodoo could still be improved a lot:

First I think that you should be able to group water,
so you can have different areas of water of different colors. This could be used well in classrooms for showing the mixes of paints(the water particles mix), water should also have a scripting menu so you can add collide and everything normal geometries have.

Secondly I think you should be able to give water a killer/cutter option, so that it works like an acid and can erode geometries. This also would be useful in class rooms, and if water was group-able then you could mix acids, alkalines and water together and neutralise it.

Water in algodoo can be quite CPU intensive, so I believe that there should be an option to change the sizes of the water particles, this would also help in making items with water smaller, so you don't have to make really big items for water.

Finally I think that you should have a material menu for the water, so that you can adjust water density, this would mean you could have completely incompressible fluids like oils for hydraulics, and then you could have normal liquids that aren't quite so incompressible, also you could have a friction menu so you can make a liquid into a lubricant, or increase it so it can have some friction. This also has an affect on the erosion of a material as that's what fluids often do.

The liquid material meter has a selection of pre-made liquids, like now, but instead of helium etc. This pre-sets what the liquid does.

It took me quite some time to come up with these ideas so please say if you think they are good or not, also I know the acid idea has been thought of before but not as detailed a description of it.

Groupable water with adjustable properties makes sense if you intend to show that mercury will float on water for instance. or that steel will float in mercury.

[Fujitsu]

You can change the size of water particles, but it involves altering SPH.radius in the console.

[niffirg1]

You can also change the density and frictioin using SPH.
But i Support

[kilebantick]

You can make your own materials, there are pre-made stencils for them in the materials folder.
The rest can be done via the console. Takes a bit longer, but it still works. Not supported, sorry beechy

no you cant kile, he said make material for WATER. such as water, mercury, oil, blood, etc

[thebeech]

ok kile, chronos knows what i mean , but changing the SPH is possible for but its not the easiest thing for people that are knew to algodoo or teachers that don't want to learn about all of it.

[guyboy]

The water properties like chronos said require too much of a modification of phun's physics to be realizable, though multiple water settings and a script menu aren't a bad idea.

There will be improvements to the water model in future releases for sure (please, don't ask when). The new method used in Algodoo is novel (and actually patented), and promises alot for the future when it comes to mixing of fluids, setting viscosity, having adaptive resolution and much more. However, this is also an area of very active scientific research, so we really implement things as soon as we have the new methods fresh from research.

[thebeech]

ok thanks ken its nice to have admin's feed back

[Sonic]

Awesome ideas! I support!
(See Chronos? I DO Support Algodoo suggestions!)

[Sniperkasa]

But also you should propably to be able to controll the "density" of the liquids grouped, for example in mixing alcohol with water.

[Nxdt]

I fully support this, but things get complicated when mixing fluids, first fluids only mix when they are either both Di-polar or both non Di-polar fluids. There should be a tick box for this. Colors should "blend" when they mix, sort of works out the average color.

[thebeech]

thanks everyone and yes nxdt that's what i ment

[Sonic]

I've got another idea. You should also be able to adjust the vaporize time of the water.

[standardtoaster]

sph.vaporizeTime = time you want

[thebeech]

but that's not the easiest thing in the world for a teacher that just wants to do a physics lesson is it ?

[standardtoaster]

:/ I guess not. Although if a teacher had a question or problem about the water then we could tell them exactly what they would need to do. Remember that this forum is for a community of Algodoo and Algodoo: Phun Edition users and Teachers/students.

[thebeech]

yes I guess, but say a student put his/her hand up in a lesson and asked then it wouldn't be possible but ah well:) I see your point and I hope you see mine

[standardtoaster]

I see your point but I will ask this question as a response. When/why would a student in the middle of the class raise his/her hand and ask "Can I change how long it takes for the water to evaporate?"

Now you see my point.

[thebeech]

Yes I see your point, but they could ask about other stuff

[Sniperkasa]

Hmm just came upp to my head.. it would be cool to be able to controll water evaporation per water drop.. so you could make vaporising on collide on an "hot" object.. would get hard propably but..

[izacque]

I personally love the acid / alkalai idea
