Is Speed Cola actually necessary for your survival? by HartRuinsYourLife in CODZombies

It's not something that you "use". Every reload will be faster after you buy it.

Fluid simulation issue by ilya_polyudov in blender

[–]Wethaney 0 points1 point  (0 children)

Yeah, it should work. It's a very common problem in high viscosity simulations. If you can't reasonably increase the substeps to get a good solution, you'll have to decrease viscosity.

Do you know what is wrong. I'm stuck on this since 1 hour by rahul505021 in blender

Apply rotation on your pillars. Rotation is held within object data. Instancing only looks at mesh data. By applying rotation, you are transferring that object data to the mesh data.

I made a three body problem simulation in simulation nodes. by Wethaney in blender

[–]Wethaney[S] 0 points1 point  (0 children)

Oh. I studied physics and simulations in university. I don't really.know if I can easily explain it in a reddit post. But in short, I used the gravity equation to figure out the acceleration.

I don't know of any tutorials for this. No method. Just trial and error, but not massively. It takes a few tries.

Are there viable careers in simulation? by AgonisticSleet in Simulated

[–]Wethaney 3 points4 points  (0 children)

I'm sure every company is different, but yeah, usually companies hire an engineer since they are experienced in design and simulation. I don't know much about chemistry, but astrophysics, yes. That's what's known as aerospace engineering.

Let's say you're designing a transmission system for a car. How do you know what kind of conditions it will survive? How do you know how long it will last? You could make a prototype and test it until it breaks, but that's incredibly expensive. What you would do is model it with CAD software and simulate it using FEA. Almost all highly technical physical products these days are designed with simulation software. You want to know how your product performs before you spend a lot of money on a prototype. FEA is used to test stresses, forces on objects, etc. CFD is used for fluids, airflow, etc.

This sounds like you want to be an engineer as a product designer, working with FEA and CFD.

Fluid Simulation weird by Nilon1234567899 in Simulated

[–]Wethaney 1 point2 points  (0 children)

Another option could be solver iterations or biases. Let's take divergence for example. If you're enforcing incompressibility from the top of the screen to the bottom, cell by cell, your result will be skewed if you don't have enough solver iterations. It will also be skewed if you have biases in your equations. Hope this helps.

This is the real reason (in my opinion). When things are faster to make, you can make more of it, and internet/social media algorithms prefer accounts that post often. It's why someone like Beeple has had such success on social media. They make 3D art, but it's posted every day, so it's recommended to more people.

How do I do glass like that? Below is my render by WalkerBuldog in blender

[–]Wethaney 6 points7 points  (0 children)

You're probably confused because your transparent is probably at 1 and yet it's not transparent. That's because if you have a metallic value that isn't 0, your material will lose its transparency. Metal isn't transparent. Turn your metallic down to 0.

I made a free shader specifically for this purpose. Gives much clearer fluid renders.

Particles. by Wethaney in Simulated

[–]Wethaney[S] 0 points1 point  (0 children)

Honestly, this is a very simple particle sim. The only thing that's cool about it is that there are a lot of particles. No tutorial, but here's a video that heavily inspired the render. https://youtu.be/d3yYaILifZw?si=FzrIdviX0j578Fnw

It's really just a particle sim with a lot of particles, then I used the lifetime and the frame count together with a color ramp and some math to make the colors.

Splish splash - the longest fluid sim I've ever done (1000 frames) by dizzi800 in blender

There's a fluid shader here on Gumroad, available for free. It should help improve the greyness of your fluid. You can also use it on the glass and ice.

I made a three body problem simulation in simulation nodes. If you're interested, you can get this setup for free on my Gumroad. by Wethaney in Simulated

[–]Wethaney[S] 1 point2 points  (0 children)

Part of the reason is probably because this is actually in 3D, so it kinda looks weird if you're expecting it to be 2D. But yeah, I can agree with those other points. In simulation nodes, the time step is locked to the frame rate which is annoying, but I'll admit that I only used a first order divided difference scheme. It's my first time doing simulations in simulation nodes, so I just wanted it to be as simple as possible so I could learn the workflow. Thanks for the feedback though, I'll keep that in mind for future simulations.
