Code for fluid dynamic in 3D written in Scilab

AI Thread Summary
A user seeks code for simulating fluid dynamics in 3D using Scilab, Mathematica, or Fortran, specifically for non-Newtonian fluids in a single screw extruder. The response highlights the complexity of fluid dynamics, noting that it encompasses numerous problems and requires an understanding of various algorithms. It emphasizes that simple code examples are rare and often involve extensive learning and multiple modules. Additionally, the discussion points out that requesting proprietary or complete codes is inappropriate, suggesting that users should refer to specialized texts for guidance. Overall, the conversation underscores the challenges of learning fluid dynamics programming and the need for foundational knowledge.

Hallo.

I am new at forum, could please somebody send me a code for fluid dynamic in 3D written in Scilab, mathematica or Fortran. I will use it to start with learning!b

Thaks,

JG

I have no idea what you are asking here. Mathematical fluid dynamics includes a huge number of problems with a huge number of formulas and algorithms. Are you asking for someone to give you all of them in "Scilab, mathematica, or Fortran"?
 


Hallo,

i would like to make a simulation of some non Newton fluid in a single screw extrudor, what is known alkso as kneader. For solving the equations of motion btw navier stokes in cylindrical coordinates I must solve a set of pde EQUATIONS. i know those three programs, but I would like to get a sample how to solve a simple system and will in next step mirror it to my sysietm.

Can you send me some example?

Thanks JG
 


It's not appropriate to ask for a code made from scratch or to ask for a proprietary code, and expecting it to be free.

One can find texts on the subject of non-Newtonian fluids, e.g., Finite Element Analysis of Non-Newtonian Flow: Theory and Software (Hardcover)

The problem is that you're asking for a simple example, or a sample code snippet, which does not exist. Even the most simplistic code could potentially involve dozens of modules and take a great deal of learning in order to understand what's actually happening.

In graduate school, we wrote a quasi-1D explicit solver (only 3 coupled equations, not 5), and it took the entirety of two semesters of class and programming.
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
