Thanks alot for your answer. I wrote a post for you but I think it was not posted successfully, so if you see my answer probably twice I appoligize to you for it. I have allready read the paper that is done in dealii and I saw the homepage that you gave me and downloaded the code. But actually my problem is that I have to input my geometry in dealii and refine it in my certain direction of the crack, which is for me not clear in the paper how it has been done in the software. I know the theory of it but how to implement it with the software is my problem. It would be nice if you could tell me how can I do it or if I can fine somewhere accordingly its tutorial or the way of it.Thank you. Kind regards Reza
