hi,

since this problem came up at least twice i may ask if somebody in this forum did NOT read the manual of this board.

please simply click the button "Getting Started" on the left side of this page and one may read something which might be connected to the word "POLITE".

best regards
Stephan

Hi weihong yao,

since this would be very impolite - please use wikipedia to figure out what rtfm means.

best regards

It means "read the foam manual", where slip boundary conditions are explained. If you need more explanations, write your questions in complete sentences, telling what you want to know, not just a keyword.

If you only spend two seconds to write "sorry,what ablut free slip?" you shouldn't expect others to spend more than two seconds on an answer. This is what I consider politeness.
