“Be careful when using Dwork vector for saving 2D-array after reshaping it into vector. Because if you choose the Dwork vector length to be equal to the total number of elements in the 2D-array. Next, you reshape the 2D-array into vector. After that, you save the "vectorized" 2D-array into the Dwork vector. Then for unknown reason, the Dwork vector will save only half of the 2D-array elements. This will be the case no matter what you try!
But fortunately, after long effort of trial and error, I found solution for this problem. Simply by choosing the length of the Dwork vector to be double...” more

“As far as I see, it has no direct way to avoid the unsymmetry via integration by parts (only switches the derivative from the solution function to the test function). It remember me the cases with weak formulation of non-self-adjoint systems e.g. advection-diffusion problems (e.g. -u'' + ku' = 0).
But, I am not an expert on that, however if you need some direction try to ask to experts in Discontinuous Galerkin as well as who uses UMFPACK. After, if possible give us here some feedback.”

A new theorem for summation of the rigid body real generalized velocities with these new additional kinematic characteristics is formulated.

The absolute motion of an arbitrary asymmetric rigid body is studied. This motion is determined after its relative motion has been obtained. The most important peculiarity in this dynamical rigid body model is that the selected pole does not coincide with its mass center. Seven new kinematic characteristics have been defined. The first ones are the following vectors: real absolute, transmisive and relative generalized velocities. The second ones are the vectors-real absolute, transmisive, relative and Coriolisian generalized accelerations. Two new theorems are formulated. The first one is...

Dike infrastructure is of vital importance for the safety against flooding. The standard methodologies for the assessment of dike safety for macrostability are based on limit equilibrium methods, which result in a safety factor against shear failure. The more advanced alternative consists of using finite element method to compute the safety factor against shear failure. However, these approaches do not take into account the capacity of the dike to retain water, but are only concerned with the mechanical equilibrium of the dike's initial composition. With the recent advancements in the...

“Are you looking for making a loop so that you "automate" calculating the flood load per each velocity..etc? If that's what you want, either create loops ( like *do loop) inside the APDL or create a macro, indeed, inside the apdl ( like the segment you want to repeat, start with "macro" ...put your code, then "end macro". OR you can save the macro code into a separate file and call for it. On either situation there is no escaping from making *do, loops inside the apdl.

The soccer ball is modeled as an ideal rigid hollow spherical body with six degrees of freedom, which performs a general motion in an immovable air environment with constant parameters. The ball 3D orientation is determined by the three Cardan angles. The aerodynamic forces and moments with which the air environment acts to the ball are taken into account.

We predicted BX monolayers with two different atomic stacking sequences of ABBA and ABBC, referred in this work to 2H and 1T, respectively. Analysis of phonon dispersions confirm the dynamical stability of BX nanosheets with both 2H and 1T atomic lattices.

We propose a study of primal and dual Steklov-Poincaré approaches for the data completion problem in linear elasticity. After giving elementary properties of the discretized operators, we investigate the numerical solution with Krylov solvers. Different preconditioning and acceleration strategies are evaluated. We show that costless filtering of the solution is possible by post-processing Ritz elements. Assessments are provided on a 3D mechanical problem.

Being able to seamlessly deal with complex crack patterns like branching, merging and even fragmentation, the phase-field model, amongst several alternatives, is promising in the computational modeling of dynamic fracture in solids. This paper presents an extension of our recently introduced phase-field cohesive zone model for static fracture to dynamic fracture in brittle and quasi-brittle solids. The model performance is tested with several benchmarks for dynamic brittle and cohesive fracture. Good agreement is achieved with existing findings and experimental results; and particularly...

A phase-field regularized cohesive zone model (CZM) was recently proposed for both brittle fracture and cohesive failure within the framework of the unified phase-field damage theory. Motivated from the fact that this model gives length scale and mesh independent global responses for problems with or without elastic singularities, we further apply it in this work against the size and boundary effects of concrete under both mode-I and mixed-mode failure. More specifically, for the two independent experimental campaigns of three-point bending notched and unnotched concrete beams under mode-I...

Conditional reliability measures provide a more detailed description of the performance of a system, being representative of different initial configurations. Commonly, since the failure region is characterised by a small probability of occurrence, advanced sampling techniques are required to reduce the computational effort of a simulation based approach. These techniques if on one hand decrease the number of samples needed to identify the failure domain, on the other hand do not generally allow a direct estimation of the conditional failure probability for different given inputs. This...

This paper proposes a new node-to-node (NTN) scheme for modeling two-dimensional contact problems within a scaled boundary finite element method (SBFEM) framework. The analysis is formulated and solved directly as a mathematical programming problem known as a mixed complementarity problem (MCP). Polygon elements with arbitrary number of edges and nodes are constructed in the SBFEM modeling. Only the edges of these polygon elements are discretized thereby accommodating highly non-uniform discretization. Non-matching meshes are easily converted into matching meshes by appropriate node...

Buildings are being constructed at ever faster rates, fuelled by population growth and urbanisation.

The majority of the mass and embodied energy (60% to 70%) in a typical multi-storey building structure exists within the floors [2], making these a primary target for sustainable structural design.

In this way the real and imaginary parts of the enhanced frequency response functions are...

In recent years, aircraft concepts and configurations have become more diverse and complex thus pushing many synthesis packages beyond their capability. Furthermore, many examples of aircraft design software focus on the analysis of one particular concept thus requiring separate packages for each concept.

Protein structure prediction (PSP) is computationally a very challenging problem. The challenge largely comes from the fact that the energy function that needs to be minimised in order to obtain the native structure of a given protein is not clearly known. A high resolution 20 × 20 energy model could better capture the behaviour of the actual energy function than a low resolution energy model such as hydrophobic polar. However, the fine grained details of the high resolution interaction energy matrix are often not very informative for guiding the search. In contrast, a low resolution...
