Fluent exceeding Solution Limits on faces
I am using Fluent with a compiled UDF to provide some boundary conditions, specifically a wall heat flux (but the UDF should be irrelevant to this particular issue). I have set the minimum and maximum temperatures in Fluent to 200 K and 2200 K, respectively via the Solution Limits box under Solution Controls. Despite this, when I use the UDF command F_T(face,f_thread) to query the temperature on a boundary face, Fluent often returns a value well outside these temperature limits (including very negative values). Do the Solution Limits specified under Solution Controls not apply to faces? How can I force Fluent to limit ALL temperatures (including faces) to these limits?
