1 Redo-speed up

 

1.1 write and save BC setups in fluent

file/write-bc bc_setup

file/read-bc bc_setup

1.2 Data Interpolation :interpolation: :write bc:

 

1.2.1 Interpolate BC and data

1.) Run the simulation for coarse mesh 2.) Write interpolate file using command file–>interpolate–>write–>save (selected all variables) 3.) Write boundary conditions using TUI: file/write-bc <file-name> 4.) Read fine mesh using command

file–>read–>mesh 5.) Read boundary conditions using text command “file/read-bc <file-name>” (read same file generated at step 3) ( the file shoud be the loading path, you can check the loading path with pwd command 6.) Read interpolate file file–>interpolate–>read–>selected same file generated at step 2

1. Reduce the under-relaxation factors and calculate on the new mesh for a few iterations

to avoid sudden changes due to any imbalance of fluxes after interpolation. Then increase the under-relaxation factors and compute a solution on the new mesh.

1.3 Replacing the mesh

if you change the mesh, you do not need to setup all models manually again, you just need to replace the mesh file

• no need to save case setting and interpolate the existing data, these are done automatically
• replace the mesh globally
