1 Correspondence to G.M. Lingaraju, e-mail: [email protected] Summary This paper discusses real time visualisation of free surface flows that are modelled using an Arbitrary Lagrangian Eulerian (ALE) approach. To integrate the dynamic simulation with the visualization, a comprehensive yet extensible Graphical User Interface (GUI) is used. The visualization technique employed is demonstrated on ...

We consider type IIA string theory on a Calabi-Yau 2-fold with D6branes wrapping 2-cycles in the 2-fold. We find a complete set of conditions on the supergravity solution for any given wrapped brane configuration in terms of SU(2) structures. We reduce the problem of finding a supergravity solution for the wrapped branes to finding a harmonic function on R×CY2. We then lift this solution to 11-...

Abstract We present a novel method for the solution of the diÆusion equation on a composite AMR mesh. This approach is suitable for including diÆusion based physics modules to hydrocodes that support ALE and AMR capabilities. To illustrate, we proÆer our implementations of diÆusion based radiation transport and heat conduction in a hydrocode called ALE-AMR. Numerical experiments conducted with ...

Laser plasma is modeled by Lagrangian hydrodynamical equations including heat conductivity and laser absorption. The hyperbolic part of the model is treated by Arbitrary Lagrangian Eulerian (ALE) method which avoids moving mesh distortion and parabolic heat conductivity part is treated by splitting and mimetic method. High velocity laser accelerated disc impact problems for which standard Lagra...

We discuss the origin of enhanced gauge symmetry in ALE (and K3) compactification of M theory, either defined as the strong coupling limit of the type IIa superstring, or as defined by Banks et al. In the D-brane formalism, wrapped membranes are D0 branes with twisted string boundary conditions, and appear on the same footing with the Kaluza-Klein excitations of the gauge bosons. In M(atrix) th...

Many studies have assessed the neural underpinnings of creativity, failing to find a clear anatomical localization. We aimed to provide evidence for a multi-componential neural system for creativity. We applied a general activation likelihood estimation (ALE) meta-analysis to 45 fMRI studies. Three individual ALE analyses were performed to assess creativity in different cognitive domains (Music...

The objective of the Arbitrary Lagrangian-Eulerian (ALE) methodology for solving multidimensional fluid flow problems is to move the computational mesh, using the flow as a guide, to improve the robustness, accuracy and efficiency of a simulation. The main elements in the ALE simulation are an explicit Lagrangian phase, a rezone phase in which a new mesh is defined, and a remapping (conservativ...

The worldvolume theory of D3-branes probing four D7-branes and an O7-plane on C/Z2 is given by a supersymmetric USp×USp gauge theory. We demonstrate that, at least for a particular choice of the holonomy at infinity, we can go to a dual description of the gauge theory, where we can add a Fayet-Iliopoulos term describing the blowing-up of the orbifold to the smooth ALE space. This allows us to e...

Mesh optimization has proven to be an effective way to improve mesh quality for arbitrary Lagrangian Eulerian (ALE) simulations. To date, however, most of the focus has been on improving the geometric shape of individual elements, and these methods often do not result in smooth transitions in element size or aspect ratio across groups of elements. We present an extension to the mean ratio optim...
