Generally speaking, how much will single precision affect solution accuracy from FLUENT? Is Double precision necessary for LES or DES?
Double vs Single
Memory: 2 : 1?
Computer Time: 2 : 1?
Accuracy: ??
yes, double precision is mandatory, not only using Fluent...
For example, iterative processes must be repeated until very small threshold value is reached, for example to ensure the divergence-free constraint in incompressible flows
can you explain in brief?
I am planning to simulate a turbulent flow with a relatively low Reynolds number using LBM, can anyone recommend a suitable open source code? OpenLB or Palabos or others? Thanks!
