hi
I have used MHD and also a udf for slip velocity in my modeling.
in the UDF I have used macro defin_adjust to Calculate the gradiant of magnetic field that have modeled with MHD in every iteration. As far as define_adjust is a Void so I save the answer in UDM . I read somewhere that udm is not exclusive space in memory and if I use dozen of udf values of udm together, it can be filled and I Know MHD has a lot of udm.
my question is how can i allocate a udm to a different memory to save it?
i wanna know is it possible to allocate udm to a different memory and if not is there any possibility that fluent fill previous memory with wrong data?
