[FAQ]

Yes, it is possible to use a UDM with the Eulerian model. By using the C_UDMI(c, t, i) macro (i being the UDM number), it is possible to save any numerical value for each cell. This data is used well in a UDF and is a very useful feature because it is also saved in Fluent data files. However, when using the Eulerian model, it requires attention. In the Eulerian model has three thread case of the calculation of, for example, two-phase. 1. mixture thread (thread of mixture thread phase) 2. Primary Thread (thread of the first phase) 3. Secondary Thread (thread of the second phase) Some variables have to have a value only at the primary / secondary thread and other variables have a value only at the mixture thread, but the UDM has a value only at the mixture thread. For this reason, it is not possible to save the numerical value for each phase even in the Eulerian model, you can save only one number from each cell. If you want to save the numerical value of each phase, you need to use two UDMs. Keywords: multiphase, UDM, user-defined memory, user defined memory, Euler, phase thread
