I am finally fed up of thinking it and want to get the ball rolling... I want to create 2 simulators

1 Tsunami Simulator
2 Earthquake Aftershock Analyser

The reason... I have a sister in Japan and I want to make sure the worst is over. ever since the devastating earthquare and tsunami in february there have been over 300 aftershocks something the media has not told you about.

Now we all should understand that many aftershocks is not normal unless something is on its way, someone with more experience in this field please correct me if I am wrong with that statement.

So I wanted to create an application that A can be used to design tsunami barriers of sort and also an earthwuake analyser both of which I believe will just require Dark Physics.

I was relieved I could make use of fluids on my current fresh install of win 7... I was only confused on how to create more than a little fluid with a single emitter water commands were confusing... I want to know how to create a large amount of fluid in order to emulate water flowing over terrain.

Hope you get my point and my goal here, I hope to turn this into a community project with a real goal to create a free publically available simulator where any country can recreate their own terrain and run simulations to help them to create prevention systems. Tsunamis are not going to remain a rarity so anything we can do to create something to help in whatever way possible I think we should make every effort to do so.. I am only a member of these forums and only know DBPro as a programming language, and I believe we can come up with something.

Thank you for your time, and please if you feel you can make something of this post up and we can make a community system to work on this together.

regards

MrValentine

Unfortunately,I'm not very enlightened on this topic,however I did find this interesting - Aftershock

Maybe that is of any assistance to you?

hmm would be useful for equations perhaps... saddened that your not enlightened...

Could be,Where I live,there never has been a tsunami and high-magnitude earthquakes aren't common either,so my interest on the subject was rather small,until this happened...

None the less,If you need anything visual done for this project,maybe some test terrains,etc. , let me know

Good luck.

thanks... I live in the UK, however I have a second home land and its Asia more specifically Japan and China, its not about not having the issue where you live, its about helping others whom do ^^ but I get your point and in some way accept your view ^^

but yeah anything that can contribute will be most welcome

I understand where you are going , however you must realize that my country is formerly socialist and really access to anything foreign was cut off until the late 90's.Heck,even food was hard to get without the proper connections...

Don't get me wrong,I'm more than willing to help someone in need,just didn't have that mentality back then (I guess you call it brainwashing).

Enough out of me though..don't want to derail the topic.

hehe I am sure a little social aspect is not too bad, yeah I know some of what happaned in the Balkans, my humble respects to you.

but yeah, consider this making a tsunami simulator can also be used inland to assess rivers, streams, reservoirs ^^ dams too... and we are all too aware what happens when a dam fails, so it can be used to simulate any water based environment to assess what would havven and where it would be safe to be, in the example of a dam failing, it could be used to assess which area of land would be safe to evacuate to and can be used in conjunction in the creation or an evacuation plan.

thanks

I know that what is going on over in Japan is terrible and if you have relatives over there it must be doubly worrying, but I'm going to have to step in and be the voice of reason.

Without meaning to cause any offence, DBPro and DarkPhysics would not be sufficient for what you are trying to do.
PhysX's fluids probably don't use completely accurate fluid models, rather fluid models that make it quick to process the data to make them seem fluid like. (Things like fluid pressure is not modelled)

You would need a greater understanding of structural mechanics and the geology behind earthquakes. To also predict the size of an incoming tsunami would require a lot of sophisticated computational work.
Really, you need Civil Engineers, Mechanical Engineers and Geologists working on this, which I can pretty much guarantee places near active fault lines employ to work on these problems daily.

If you are interested in finding out how Engineers and Scientists computationally solve these problems, look into MATLAB, which is a C like language built for solving scientific problems.

I know, but the spin off from this would be the capability of using the gained experiences for the people involved and the following readers to make use of the code generated and mainly also make it free and affordable for smaller companies/groups of people who do not have millions of (currency here) of government funding and wish to see on any scale a measure of analysing these elements.

I'm sure these exist and are used by scientific boffins, as described by BiggAdd. While you're intentions are noble, when you decide to make something complicated like this, you have to ask yourself:

Why am I making it? If the answer is for fun, go ahead. If the answer is to sell, or make available to professionals etc. you have to then ask yourself am I qualified/knowledgable/smart enough to make it, has someone done it before, and is it better than anything I can do?

I don't know you, but I agree with BiggAdd that to do it properly you'd have to be a PHD level mathematician with an expert knowledge of geology, plus have access to a lot of raw data from historical earthquakes. If you tick all those boxes, you could probably spend a few years and make something truly useful, but if not, then I refer you to "has someone done it before, and is it better than anything I can do?", and I'm pretty sure the answer will be yes to both of those questions.

It's a noble pursuit, but I think it'd be time wasted. My 2 cents.

thanks, but yeah I am trying to say its not intended to be 100% accurate, only a rough simulation perhaps the eartquake one will be an impossible with what we have, hwoever I do believe we can at least simulate the flow of water and see in draft detail where it might spill to first and perhaps its flow speed, so its just to get an rough idea of the best places to run to if you follow my lead,

dont think I dont know what your telling me already, im not that numb (as we all can be sometimes lol come on admit it lol)

but my simple point is to at least attempt at it, for the water simulations its not a huge difficulty
I know how to load terrain and make it phy enabled, im just stuck with the water commands everything ive found so far has other elements blended in... have a look at the competition 2008 demos, the source code is poorly documented.

if no one is even bothered with this, I just want to know how to add and control water aspects from Dark Physics and I shall no longer waste your time with this, thanks.

You know man, if you think you can do it then you can! I wish i could help you with DP but i have no experience there...

DarkPhysics wouldn't, for the reasons you said. But I think DB would technically work if he were to write his own physics engine. The simulation certainly wouldn't run in realtime, but neither does Nasa's bomb simulator. (at least I think it was nasa that wrote an a-bomb explosion simulator) Whoever it was, it can take weeks to run a realistic simulation with precise effects.

First of all, let me applaud your willingness to help those in need with the skills we have as humble software developers. Second of all, let me reassure you there are those like us specialized in their subject doing this. Third of all, let me try and say what BigAddd said in words that fit the scope of your ambitions: If anyone trusts whatever you're making (while not understanding the water commands in DBP) in the case of a real tsunami, you have a good chance of ending up with that person being nominated for a Darwin Award in addition to suffering a severe case of dead.

Water is hard to simulate, thats why we spend millions to hire engineers, physicians and geologists to do this kind of stuff. DarkBASIC and Physics are created to make games and offer simplified models of reality to make us feel the games behave realistically. Things like Surfing Games and Rafting Racer.

thanks guys, I know pretty much most of whats been said here, however I thank you for the input nevertheless... I think I worked out a method to recreate land masses for the terrain I just need help with the DP water commands...

also it was my bday yesterday and I got my new blog live click my banner to go there I will be updating my banner soon.

Regards

MrValentine
