Automating using steady state solutions to feed transient
 
Hello,
I am using ANSYS fluent workbench to run a steady state solution to initialize a transient solution. I have successfully done this manually but having trouble automating the process for different parameters in workbench (my parameter is inlet velocity and a changing dt for the transient simulation). I have tried writing a macro within the Calculation Activities and this works for the current design point but when it shuts down Fluent to run the other design points, or I have saved the project then open it again, the macros have disappeared. The ANSYS manual suggests using workbench to link one solution into another but this doesn't seem to work either. Has anyone successfully done this? Are there other ways to go about this? Thank you in advance!

Have you tried a journal file?

Hi LuckyTran, thanks for the reply - I have not tried a journal file, I haven't used this method before. Do you know if these are useful for running multiple parameters through Workbench or do you set up the journal file to run through multiple parameters just using Fluent?
