Web-based simulation of systems described by partial differential equations

Abstract

Esta es la versión de autor de la comunicación de congreso publicada en: This is an author produced version of a paper published in: ABSTRACTThis paper describes how to take advantage of Internet services and object technology to solve 2D partial differential equations (PDEs) in a distributed manner. This is accomplished by means of a distributed object oriented continuous simulation language designed by our research group, called OOCSMP, and a Java (and C++) generating compiler for this language (called C-OOL). We also describe a graphical mesh generator, which produces OOCSMP code. The mesh generator may be invoked from the simulation model allowing the generation of domains and meshes during model execution. The simulation of the heating of several moving pieces is shown, in the single machine case, and in the distributed case.

Visual Interactive Simulation for Distance Education

“…Other ways to integrate simulation and Web services [11] are distributed execution [12] and distributed modeling [13,14]. In the distributed execution of continuous simulation models in the Internet, one cannot use traditional ways of fine-grain parallelization (such as solving a set of equations in parallel by assigning one or a few elements of the resulting equation matrix to each node in the network).…”

“…One approach is to express the model as a collection of objects that interact, group the objects that interact more frequently, and place them in the same machine. Objects in different machines will interchange messages through the network, possibly using remote method invocation techniques [12]. This approach is similar to that taken by the High-Level Architecture (HLA) (see http://www.dmso.mil) for the parallel execution of discrete simulation models.…”

“…Figure 11 shows an excerpt of the necessary SODA-1L code to describe this page. The listing shows how to use SODA-1L to define the page title (line 7), some textual explanations (lines 8-10), a table with a caption and images (lines [12][13][14][15], and how to invoke the previously defined OOCSMP model (line 18). The MODEL instruction has some parameters to customize the user interface that C-OOL generates for the simulation.…”

“…Many disciplines are re-evaluating their strategies and techniques in view of the services offered by the Internet [6]. Simulation is as much affected by this technology as other techniques, because it represents a fertile area for performing computer simulation research [7][8].…”

Virtual Tools for Remote Analysis and Simulation

“…• Web-based simulations: Some examples of Web-based simulators are in [6], [7], [8], [9], [10], [11] and [12]. These examples present client-server architectures, in which the clients access calculation systems with minimum configuration levels and with specific objectives.…”
