Thanks a lot. This is really helpful. I still cannot turn on the read_kf to true. I am trying to simulate the imposing tangential velocity tutorial. So, I initially created a drum geometry, regions for initial particles, inlet, outlet, and wall. Defined mesh, initial conditions, and boundary conditions. For this tutorial, I am asked to create a text file with time and velocity values. I have used the same values as in the default tutorial. Now when I copy the required .f and .inc files, I couldn’t find the usrnlst.inc in the mfix source. However, I proceeded with compiling with the build solver button. The building was successful. I believe for the keyframe file(the text document with velocity data) to be read, it is necessary to turn on the read_kf to true in the advanced pane. This is where I face issue. I couldnt find the read_kf option. I also tried copying the usrnlst.inc from the default tutorial, but then when I try compiling using the build solver button, it throws an error. I don’t know where I am going wrong. Please shed some light.
Thanks in advance.
