hi i have a problem with using UDF available in the following site http://www.stanford.edu/class/me469b...ing.pdf#search=%22low%20re%20ke%20model%2Budf%22 this UDF is for low-reynolds number-ke model by using scalar equaitons by deactivating the k and e equations. when i compiled the udf its getting complied but when i am initialising the velocity inlet, i am getting fatal error. i dont know the reason why i am getting this fatal error. pls can anybody try it out and tell me the solution. thanks for ur patience.

have you enabled all the UDS and UDM memory slots in the solver?

Also, the Low Re k-e model is already available in Fluent but it has to be enabled using the text user interface.

thanks for reply i enabled all UDS in the solver. yah i know that low-re-ke model is available in fluent. but i want to try with UDFS and compare the results with other models
