Here I came up with something which is simple.<br data-mce-bogus="1"></div><div>First thing is, I was trying to access the co ordinates of the inlet boundary elements for my free stream turbulence model(Von karman).</div><div><br data-mce-bogus="1"></div><div>I have an idea to get the using cbc(f,e,1) but I just would like to know is there any quick way to get the inlet bounday nodes coordinate.<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Second thing is about the making of random numbers.<br data-mce-bogus="1"></div><div>I know that in fortran there is an inbuilt function to generate random numbers (call random_generator(iseed)) but it seems it is an expensive process since my number of modes of turbulence model is 150.<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>So just I have a question that how you usually generate random numbers when you model free stream turbulence?<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>By the way I have completed the FSI calculation of NACA0012 at Re 64000 in NEK5000.
