Hello,

The written UDF attached below is supposed to be used in my project. I'm using Ansys Fluent which needs UDF to impose a desired time-dependent function in BC's. I've imposed this UDF and it worked out, but the thing I miss is that my function has to have a specific time step that controls its shape. The desired time step that I need is (0:0.025:0.5). Also, the function is periodic so it is supposed to repeat itself back and forth.I suppose I should use (For ... Loop) to enhance such time step. Unfortunately, I'm not quite good at coding So I hope somebody can help me to rewrite the code with the desired time step mentioned previously.

Thanks in advance!!!
