Pulling a net tight

Cloth Sewings springs I would add a sewing edge to each corner of the surface and set its ending point to a pinning group. From the linked page of the manual: ...Sewing springs are virtual ...

wind / pressure inside a volume?

Simulating actual airflow and pressure would require complicated fluid dynamics simulation - but you could simulate the effect using Soft Body physics. Create you mesh and add Soft Body in the ...

Blender 2.8: Restrict influence of Force Field to its Collection

I hope it's not too late for this answer, I just found out how to do it. In the properties of your particle system, at the Field Weights tab, there's an option named Effector Collection, select the ...

Cycles smoke not responding to wind

Wind Falloff The force field in the scene is being affected by a high dampening due to the simulation of gravity introduced by the Falloff settings you are using. The wind is now acting as if it was ...

How to add a force pulling some vertices of a cloth?

Create your sail, assign the vertices on the right and on the left to the same group. Give your sail a cloth simulation, choose the group as Pin Group. Select the vertices on the right and press CtrlH ...

What does seed control in force fields?

Various data that is generated for things like simulations will use random numbers to get their results. In reality, we don't get true random numbers, we get pseudorandom numbers, which is a ...

What does seed control in force fields?

More detail can be found here. The seed input determines the noise pattern of the force. This makes the force uneven and more realistic, especially useful for wind simulations, but also when dealing ...

How to create tentacles moving with the wind?

You can achieve this by using a Soft Body Lattice to automatically deform your mesh and react to the physics. The advantage of this over making the whole mesh a Soft Body is that each tendril can be ...

How does the Turbulence Force Field work?

A force field is a vector field, meaning at every point in space it defines a vector based on some vector-valued function. In the case of a force field, the vectors represent forces pushing the ...

"Time remap" or slow speed of cloth particles driven by a force

Final: Overview: This is pretty easy solution surprisingly. Only thing you need to do is keyframing Cloth > Speed > Multiplier value. Slow down speed is exaggerated in this example just to be ...

How to get wind to affect hair particles with group or object render

Finally I understand what @Brenticus was getting at when he kept using the word "deform"! If you use either the "Object" or "Group" methods to render the particles, you can in fact affect the rotation ...

how to make sure that the forcefield does not affect particle system

You have two possible options in the Particle Properties. It depends on if you only want to keep those particles from being affected or if you want them to be effected by force fields but not the ones ...

Wind force field not working

I had a similar problem, and my flag started to react to the wind force once I scaled it up 10 times. The bigger the flag was (in Blender Units) the more it reacted to the wind force. Check your ...

How to enforce planetary gravity on fluids?

You could use particles set to 'Fluid' type and rendered using a Metaball as the dupli-object. While this won't produce a full fluid simulation it might be good enough for your usage. Using particles ...
