OK,
Im frankly speaking getting a bit tired of some of the postings here and need to let off some steam.

There are a couple of issues I feel the need to address so we can improve the quality and intention of this forum.

1. If you see that your question is not getting an answer it is because you are either not being specific enough or that its difficult to understand what the problem is. Either way, I dont have a crystal ball and I cant guess your problem.

2. There is no need to post the EXACT same question multiple times (we got it the first time)

3. There is no need to post the EXACT same question under different threads, this will only
lead to the same question being discussed in different places.

I want to help out as much as I can when people have problems to promote the spreading of OpenFOAM, but christ people. If I have to guess your problem I will/can not help.

I think there are 2 main problems you need to consider - choose a relevant subject of your question and try to be clear about what the problem is and if you have some sort of error output then it often helps to supply it.

If you still find that you dont get an answer dont post it again, please. Try to reformulate it. There are no stupid questions, we have all been beginners, but I sometimes get the feeling that the person posting the question doesnt event know what he/she is doing and how can you expect help when we have to guess your problems.

There I've said my piece,

Yours,
Niklas
