Your videos are really very helpful. Thank you for your efforts. I have a question how do we realize that we have to use hybrid initialization or standard initialization ?
It depends on the problem. If you want to put the initial guess or any initial conditions you can use standard initialization. If you don't want to put then you can go for hybrid initialization.
i got a average velocity i need to have on inlet. can i somehow inpliment it into this formula to get the velocity_max to achieve this average velocity?
@@AnsysTutor At the Moment we insert a v_max as our starting velocity. But thats not the same as the "average velocity" over the whole inlet. Is there a way to just insert the de desired "Average velocity" rather than inserting v_max and use some iterations on calculating the average velocity appearing.
@ansys Tutor, please what is the difference of selecting "outlet pressure" and "outflow" for the outlet boundary condition. does it means the pressure at the outlet is 0. which selection can be used for the pressure at the outlet have zero pascal value
hi Expert, the below expression for the velocity profile 0.001[m/s]*(1-(x**2+y**2)/(10[mm])**2). was the velocity of the problem given as 0.001 and the Radius of the pipe wall given as 10mm.
Thank you for tutorial, i want ask, I want to ask, I tried to make a truck model in Ansys 2020, but after meshing when I entered the fluent black screen setup, could it be fixed so the screen wasn't black ?
I tried following your steps, I get an error message ("Empty Value") when I finish entering the velocity profile equation. what could be the problem. should I put a value for the x and y component OR Ansys understand it and solve accordingly
No need to put x &y value, only you need to check the expression , check if you had mentioned all the units and parameters etc. There should not be any space inbetween.
hello sir, how do I correct the following abnormally on the simulation carried out: 1. there seems to be something strange happening with my velocity near the inlet. 2. I expect the v velocity to be 0 or nearly zero everywhere. 3. The pressure drop should be linear. but I am getting a different value
For 2D case if flow is along x then its in xy plane or xz plane. For xy plane its similar as per the tutorial,but for xz plane you should take r =sqrt(x^2+z^2)
Thanks for the helpful videos. Can you make a video in which the Fluent data is transferred to Excel to show flow profiles? Subscription is already safe for you.
This can be easily done in CFD post processing, you need to insert a line as the location & can import velocity at these probe points to excel as .csv file. Thanks for your subscription because it motivates us to stay on this platform.
