Normally, we steer clear of DIY products on this site. The Bottlehead Crack is the exception. It has a legendary place within the headphone community, and with good reason. The Crack ships ready to be assembled, with detailed instructions, and only requires a soldering iron to build. It doesn't really deserve a spot on the main list - it's kind of in a class of its own - but if you have the adventurousness to build it, you'll unlock headphone perfection.
I fix it before by uninstalling unity hub and editor and installing again, it last for 2 days and the problem starts to show again. Did anyone here know a permanent solution? I need to fix it by now because we have only limited time making games and Im just new to game dev thank you for the answers.

For me, it has something to do with the wifi network I am using. If I am connected to some of them I cannot open my project.I think, but am not sure. If you do not allow Unityhub to use public or private networks it will not open your project because it can not check if your license is valid. If you for example allowed unityhub to only use private networks mybe try marking the network you are using as private. Or vice-versa.
what is the exact water mark you are getting? i am using unity 2017 4.8 personal edition but i get nothing like that. if someone checked development build then there is a water mark of "development build" in lower right corner.
Open website, upload the saved Unity_v2018.2.18f1.alf file, and generate a new license. After downloading, use this menu again to load the license, restart the unity watermark. . Note that you must restart unity after activation.
Hello everyone, I just found the true solution to t$$anonymous$$s. It's all because of C$$anonymous$$na. There are too many cracked version of Unity in C$$anonymous$$na. My best guess is that Unity is targeting C$$anonymous$$nese ip and putting watermark on C$$anonymous$$nese users. And probably because Unity considers Taiwan as part of C$$anonymous$$na, so Taiwanese users also get the watermark. So I use VPN and change my ip to a United States' ip. And then manually activate the license, restart Unity, the watermark disappears after building the game. If you are having t$$anonymous$$s issue, you are probably a C$$anonymous$$nese or Taiwanese user.
In several of the cases listed here, the game's developers released the source code expressly to prevent their work from becoming abandonware. Such source code is often released under varying (free and non-free, commercial and non-commercial) software licenses to the games' communities or the public; artwork and data are often released under a different license than the source code, as the copyright situation is different or more complicated. The source code may be pushed by the developers to public repositories (e.g. SourceForge or GitHub), or given to selected game community members, or sold with the game, or become available by other means. The game may be written in an interpreted language such as BASIC or Python, and distributed as raw source code without being compiled; early software was often distributed in text form, as in the book BASIC Computer Games. In some cases when a game's source code is not available by other means, the game's community "reconstructs" source code from compiled binary files through time-demanding reverse engineering techniques.
This paper proposes a stable generalized finite element method (SGFEM) for the linear 3D elasticity problem with cracked domains. Conventional material-independent branch functions serve as singular enrichments. We prove that the proposed SGFEM with the geometric enrichment scheme yields the optimal order of convergence in the energy norm, O(h), for fully 3D elasticity planar crack problems; h is the mesh parameter. To improve the conditioning of SGFEM, two stability techniques have been employed, namely, (a) a cubic polynomial has been used as the PU (partition of unity), instead of the standard FE hat-functions, to address the possible almost linear dependence between the PU functions and the enrichments, and (b) a local principal component analysis (LPCA) has been implemented to address the local bad conditioning produced by multi-fold enrichments at a node. The scaled condition number for the proposed SGFEM is shown to be \(O(h^-2)\) (same as that of a standard Finite Element Method), for various relative positions of crack surface and mesh. The robustness of the scaled condition number for the proposed SGFEM, with respect to the relative positions of the crack-surface and the element boundaries, has been observed numerically. The numerical experiments for both the planar and fully 3D planar crack problems are presented to show the efficiency of the proposed SGFEM.
The goal of this paper is to establish that a SGFEM with material-independent BB (Belytschko-Black) enrichments (3.4) in [11, 24, 33] (instead of material-dependent OD enrichments) could be obtained for 3D linear elasticity problem with a crack. This SGFEM will have the features (i)-(iii) mentioned above, in particular, the conditioning of the method will not be worse than that of the FEM. However, it requires some additional modifications - (a) the standard FE PU hat-functions are replaced by another piecewise polynomial PU functions [13, 43, 44, 46] to address the possible almost linear dependence between the PU functions and the enrichment functions; and (b) a local principal component analysis (LPCA) [22] is employed to remove redundancy in multi-fold enrichments at a node. We prove that the proposed SGFEM yields O(h) rate of convergence (optimal) in the energy norm with the geometric enrichment scheme for a fully 3D planar crack problems [21, 36]. To the best of our knowledge, a mathematical analysis of the convergence of the GFEM/XFEM for 3D elasticity crack problems is not available. We also show that the SCN of the stiffness matrix of the proposed method is \(O(h^-2)\), which is same as that of the standard FEM. Furthermore, we establish the robustness of the conditioning of the proposed SGFEM with respect to the relative position of the crack and the element boundaries. While the singular enrichments (3.4) are material-independent, they can uniformly resolve both the planar and fully 3D planar crack problems [21, 36] efficiently, as demonstrated in the numerical experiments.
The paper is organized as follows. The 3D crack model problem is described in Sect. 2. Various existing GFEMs are introduced in Sect. 3. The SGFEM with general PU functions is proposed in Sect. 4, where we prove the optimal convergence order of SGFEM with BB enrichments for the fully 3D planar crack problems. In Sect. 5 a cubic PU is constructed, and the LPCA has been implemented to overcome the almost linear dependence caused by the multi-fold enrichments at a node. The numerical experiments and concluding remarks are presented in Sects. 6 and 7, respectively.
For a domain D in \(\mathbb R^3\), an integer m, and \(1 \le q \le +\infty \), we denote the usual Sobolev space by \(W_q^m(D)\) with norm \(\Vert \cdot \Vert _W_q^m(D)\) and semi-norm \(\cdot _W_q^m(D)\). The space \(W_q^m(D)\) will be represented by \(H^m(D)\) in the case \(q=2\) and \(L^q(D)\) when \(m=0\), respectively. We note that D can be a cracked domain with a crack surface \(\Upsilon \), and in this case, the functions in \(W_q^m(D)\) may be discontinuous on \(\Upsilon \). Since the elasticity system is considered, we denote the vector-valued function space by \(W_q^m(D;\mathbb R^3) = W_q^m(D)\times W_q^m(D)\times W_q^m(D)\). We use characters in bold, e.g., \(\mathbfu\), to represent vector-valued functions in \(W_q^m(D;\mathbb R^3)\) or vectors in \(\mathbb R^3\), and denote \(\mathbfu=[u_1, u_2, u_3]^T\). The norm in \(W_q^m(D;\mathbb R^3)\) is defined by \(\Vert \mathbfu\Vert _W_q^m(D;\mathbb R^3)^2 = \sum _i=1^3\Vert u_i\Vert _W_q^m(D)^2\).
Let \(\Omega \) be a bounded cracked domain in \(\mathbb R^3\) with the crack surface \(\Gamma _O\), where O is the crack front, see Fig. 1. \(\overline\Omega \) is the closure of \(\Omega \), and \(\Gamma = \partial \overline\Omega \) is the boundary of \(\overline\Omega \). The unit outward normal vector to \(\Gamma \) is denoted by \(\vec n\). \(\Gamma \) is composed of \(\Gamma _D\) (where an essential boundary condition will be prescribed) and \(\Gamma _N\) (where a natural boundary condition will be prescribed), i.e., \(\Gamma =\Gamma _D\cup \Gamma _N\) and \(\Gamma _D\cap \Gamma _N=\emptyset \). For simplicity of presentation, we assume that \(\Omega \) is a plate of thickness 2t given by \(\Omega = \varpi \times [-t,t]\), \(t
which is associated with a planar crack problem in that it is constant along the z-direction. If A(z) is taken as \(1+z\) or \(1+z+z^2\) for example, we have fully 3D planar crack problem (neither plane strain nor plane stress), which involves factors \(r^\frac32\) and/or \(r^\frac52\). Both the planar and fully 3D planar crack singularities are resolved in this paper.
It can be checked that (2.5) can be written as (2.8), and the last two terms in (2.5) satisfy (2.9). The term \(A(z)\mathbfS^\frac12\) in (2.8) is referred to as the major singular function of \(\mathbfu\). We note that there is an essential difference between 2D and 3D crack problem, and in 2D the major singular function is like \(\mathbfS^\frac12\), which is much simpler than \(A(z)\mathbfS^\frac12\).
The singular part \(A(z)\mathbfS^\frac12\) of (2.8) in the paper addresses only the edge-singularity. However, there is also a vertex-singularity where the crack-front (a vertical line in this case) intersects the boundaries \(\varpi \times \t\\) and \(\varpi \times \-t\\). To the best of our knowledge, the analytical form of the vertex-singularity is not known. In this paper, we assume that the solution is not affected much by this singularity (i.e., z-component of the singularity has small magnitude) and the error in considering the singular function \(\mathbfS\) is small. We mention that we have incorporated the analytical form of the edge-singularity into the approximation process, discussed later in this paper. However, if the vertex singularity becomes available, that information could also be similarly incorporated into the approximation process. \(\square \) 2ff7e9595c
