However ,I just had a question about running the mass fraction parameter. &nbsp;So I executed the commands as specified in the document &nbsp;and it runs perfectly if I have the fluent window open and just change the parameter value in the workbench. However , it fails to initialise while running in automation unsupervised. Right when it switches to the next design points and undergoes setup changes . I get the error in the solution monitor as &lsquo; unable to find rpvar&rsquo;. I have been looking at some solutions however , I havent found one suitable.&nbsp; To expand on this , the simulation will run once I initialise it and if I need to run it again , it fails with the same error .&nbsp; All I have done is parameterise the mass fraction using rp var define command and use the lambda script procedure to assign the value .
