fluctuation in simulation
 

Hi,

I am running my 2D simulation, using dynamic mesh.

Everything is working, except an unwanted flow which is an error developed next to a wall entity.

What can I do to fix it?


Thank you

Do you really believe that this is enough information for anybody to give you any useful advice?

Your question is similar to: "I have a car, which is usually running fine, but in some situations it does not. What can I do to solve it?" If you ask such a question to a car mechanic, he will not be able to give you any useful advice. He will need to see details, and it is the same here.

Look at the solution you have now, and try to think which things could be useful for people that want to help you. Add a picture of how the (unwanted) flow close to the wall looks like. Add a picture of how the mesh there typically looks like. Such things.

Hi,

I just think everybody with me in my case....
File is attached. Please notice the field formed at the right edge of the tank.
Its not suppose to be there, its came from nowhere.

Thank you:confused:
