Water stream problem

Hi

i try to generate a constant stream of fluid particles. this works, but i need it to fly an specific distance. The problem is when i increase the motionLimitMultiplyer my fluid fly's long enough but it has gaps. How can i close the gaps?

here is my fluid and emitter description:

float radius = 0.02;
float rPpM = 1.0/radius;

// create Fluid
NxOgre::FluidDescription desc;
desc.mMaxParticles = 32000;
desc.mKernelRadiusMultiplier = 1.0f;
desc.mRestParticlesPerMetre = rPpM;
desc.mMotionLimitMultiplier = 8;
desc.mPacketSizeMultiplier = 8;
desc.mCollisionDistanceMultiplier = 1.0f;
desc.mStiffness = 5.0f;
desc.mViscosity = 100.0f;;
desc.mRestDensity = 1000.0f;
desc.mDamping = 0.0f;
desc.mFadeInTime = 0.0f;
desc.mRestitutionForStaticShapes = 0.10f;
desc.mRestitutionForDynamicShapes = 0.10f;
desc.mDynamicFrictionForStaticShapes = 0.50f;
desc.mDynamicFrictionForDynamicShapes = 0.50f;
desc.mCollisionResponseCoefficient = 0.10f;

NxOgre::FluidEmitterDescription edesc;
edesc.mParticleLifetime = 2.0;
edesc.mRate = 300;
edesc.mFluidSpeed = 100.0f;
edesc.mType = NxOgre::Enums::FluidEmitterType_Pressure;
edesc.mReplusionCoefficient = 0.00f;
edesc.mDimensionX = 0.020f;
edesc.mDimensionY = 0.020f;


here you can see the gaps:

Never played with fluids, so this is total shoot in the dark, but perhaps increasing the rate for the emitter would do the trick?

That was my thought as well, and perhaps playing around with the particle lifetime.

hi,

hmm flow rate doesn't work because the emitter has the constant pressure type.

i played with the particle life time but doesn't change anything. Only if i set the motionLimitMultiplyer to 4 the stream has no gaps.

Maybe can i speed up the stream with a force field in front of the emitter?

You could try, but that is a lot of effort if it doesn't pay off.

I'm sure it can be solved by just altering the description. I haven't played with Fluids for a while now, so I'm not much help.

hi,

i've tried some settings and get the gaps with the following smaller


float radius = 0.03;
float rPpM = 1.0/radius;

// create Fluid
NxOgre::FluidDescription desc;
desc.mMaxParticles = 500;
desc.mKernelRadiusMultiplier = 1.0f;
desc.mRestParticlesPerMetre = rPpM/2;
desc.mMotionLimitMultiplier = 4;//2*radius*rPpM;
desc.mPacketSizeMultiplier = 8;
desc.mCollisionDistanceMultiplier = 1.0f;
desc.mStiffness = 8.0f;
desc.mViscosity = 50.0f;;
desc.mRestDensity = 1000.0f;
desc.mDamping = 0.0f;
desc.mFadeInTime = 0.0f;
desc.mRestitutionForStaticShapes = 0.00f;
desc.mRestitutionForDynamicShapes = 0.10f;
desc.mDynamicFrictionForStaticShapes = 0.20f;
desc.mDynamicFrictionForDynamicShapes = 0.20f;
desc.mCollisionResponseCoefficient = 0.1f;
