Hi! It's a useful video! Can someone tell me how is build the x-motion profile? I'd like to kwon how to change it by my own depending on the movement I want to give (ex go back and forth, what speed and so on). Thank you in advanced!
Thanks. I briefly explained in the video. Just re-type what I showed and change the numbers...two number for the time indicates the beginning and end of motion, the same applies for v_x showing the respective velocities. if you need more info, search for how to write profiles for Fluent but if your motion is simple, you can use what I showed.
@@pulsedflowsolutions9058 thank you! I tried, changing positive values it works; but if I try to use negative value I do not manage. ex: ((x_motion 3 point) (time 0.001 0.002 0.003) (v_x 0.05 -0.05 0.05) and in the mesh motion preview I use 0.001 for the timestep size and I set 300 as number of time steps. I've also read about how to write profile in Fluent now as you said, trying to use this ((x_motion transient 3 0) in order to assign different values at velocity, but it doesn't work too. Last question is if you have an idea for this? anyhow thankyou!
Good video, here why you are making the surface_top to move with the flow. If wall body is moving in fluid the adjacent top_surface will not move in real scenario.
The Fluent manual is not clear about this but I guess this is merely for mesh generation and it doesn't mean that the flow in the top region is moving with the same speed. However, I am not sure about this. You need to run the flow simulation to ensure this statement.
great video, i followed this video step by step but i faced "float point exception error" after clicking run calculation, what should i do?
Why are we not fusing all the interfaces as interiors?

Ali Moslemi thanks for your quick reply
thank you so much!
