My case is that:in a centrifugal pump,the impeller is rotating ,so the fluid is rotating too.The rotational speed is vary with time such as sin(t). You suggested me that I can define the fluid rotation using UDFs even though you don't have hook to attach the UDF

Use DEFINE_ADJUST macro and THREAD_VAR(tc) = your function

to define the rotation

My problem is that:after I compile it and load it,what should I do next? Could I have your email?

Regards lingo
