Re: converging large space with k-e model

Is my result still valid using the constant viscosity method?

It is my understanding that constant viscosity method will introduce an artificially high level of diffusion into my model.

Since I am modeling distribution of CO2 in my large space, is the cosntant viscosity method appropriate?

converging large space with k-e model

Hi,

I'm working on a very large space in microflo.

When I use the Constant Effective Viscosity method, my solution converges, and I seem to be obtaining mesh independence.

However, when I apply k-e to the model, it cannot reach convergence, even after adjusting time steps etc.

attached is my ...

Assigning memory to IES

Hi,

I'm currently working on a CFD for a large space but I cannot refine my mesh small enough without the program running out of memory.

Even though I am using a 16GB RAM computer, MicroFlo will only utilise about 4.5GB. How can I assign more of the memory to MicroFlo so I can refine the mesh more?
