LOSTSTARS New Member wq yang Join Date: Oct 2023 Posts: 7 Rep Power: 2	Dear Sir/Madam, Recently I've been working on the post-processing of a flame. However, I encountered a problem. I used to get data of the flame front by creating an isoface in fluent and reading the data in Excel, but when I want to calculate the secondary gradient of temperature along the flame front, I have no idea (I want to use the macro F_C0 and F_C1). So how can I identify and extract the flame front using UDF? Or is there any method to calculate the flame displacement speed or flame consumption speed using UDF? Thank you.
