How can I reuse the results from a previous Fluent run to initialize my current Fluent calculation
File interpolation can be used to utilize the results from a previous Fluent run to initialize the new run. This will help reduce the computation time. To do this, you will write out an interpolation file from the previous run and then read in the interpolation file into the second run to initialize the flow field.
Create Interpolation file:
Read in your case and data files from your previous run.
Go to FILE -> INTERPOLATE.
Under OPTIONS, select WRITE DATA. Under FIELDS, select the desired interpolation variables, for instance, temperature, velocity etc. Under CELL ZONES, select the desired zones. Click on WRITE to write out the interpolation file.
Use Interpolation file:
Read in your new case file into Fluent
Go to FILE --> INTERPOLATE. Under OPTIONS select READ AND INTERPOLATE. Under CELL ZONES, select the desired zone(s). Click on READ and read in the interpolation file you wrote previously. The flow field will be automatically initialized via interpolation from your previous results
