hi dear experts

static friction coefficient in what issues can be used? i have many tried to finding it's application in help of the software, but unfortunately i can't find any subject relevant to it.

The only thing I could find about it I've given below:

The rough component should be assigned a no-slip surface (via a negative static friction coefficient).

Is it only applied to simulate the flow in the pipes Or can also be used in open channel?


would be grateful for any commnets & introduce reference to it.

best regards
hamid

This variable is discussed in the Model Reference->Viscosity and Turbulence ->Wall slipe section of the help manual.

Use a negative value for a no slip surface, and and positive values for partial slip surfaces. Applications where you might want a partial slip are some type of coating inside of pipe. It could use it for a channel application, but not sure for what purpose. As the modeler, you would need to decide if it is correct for your application.
