Hi , I think I have solved the mesh issue now . However ,I just had a question about running the mass fraction parameter.  So I executed the commands as specified in the document  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 ‘ unable to find rpvar’. I have been looking at some solutions however , I havent found one suitable.  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 .  All I have done is parameterise the mass fraction using rp var define command and use the lambda script procedure to assign the value . I have only followed the steps given here https://www.computationalfluiddynamics.com.au/how-can-i-drive-fluent-udf-parameters-directly-from-ansys-workbench/
