Re: 2D PJ Pressure analizer

No I´m not conserving the impulse.

i tested to see bernoulli effect, and an air foil and it dont work. I think i know what need to be done.

Going to correct this.

Re: 2D PJ Pressure analizer

Rossco, Thanks very much for your reply. (the better part of making a software for the community is to see others trying and using it!!) What is it written in? Can the extremes of the image not be walls? Sofar... very fun toy. Will be watching. It is written in pure C. I have tried to make the limit...

New Software for 2D Simulation

I´m making a simulation software, If someone is interested you can download it here: http://www.badongo.com/file/24174871 http://www.4shared.com/file/aL5C4Xty/2D-FlowSim.html Just save a image with max 1024x1024 in TGA greyscale (draw on paint and convert using xnview to 256 grey scale and to tga) T...

Re: 2D PJ Pressure analizer

Software RELEASED!!!! Just save a image with max 1024x1024 in TGA greyscale (draw on paint and convert using xnview to 256 grey scale and to tga) The black 0x00, is borders, any other grey is local pressure, 128 grey is 0. the image is pj.tga (next version i will you the filename inside config.cfg) ...

Re: Focused wave engine runs!

An video for a crude simulation from the software I´m making for this engine.

for a beginner, I´m thinking in building this design, it is better to try another one?
I think the properties of this design is good for a beginner.

Re: 2D PJ Pressure analizer

Just draw a simple open tube on paintbrush, and put to simulate.

This is the results:

Re: 2D PJ Pressure analizer

Some demos, without PJ walls

the simulation resolution is 10x10 nodes.

i put a point initial pressure on this video:

And 3 pixel points initial pressure on this:

2D PJ Pressure analizer

Hello all, this is my first post, I´m Robinson from Brazil and graduated in Engineering of control and automation. I have the wish to build a PJ for some time now, the first one will be probably Short Lady from Larry. Well, when i buy the necessary tools, I post something about that. (i dont have ac...
