ProSIM is a modern web application designed and implemented in "Ruby on Rails" especially for CST simulation toolkit to work as a communication and collaboration layer between the simulation experts and other design and planning teams

ProSIM is open source and released under the terms of the GNU General Public License v2 (GPL).(get the source code)

Demo simulation models:

  1. MefistoFlugsteig
  2. MefistoHochhaus

Selected results of demonstration projects:

4D Animation
Animation for the minimum project duration(click here for a full screen animatione)

Construction Simulation Toolkit (CST)

CST is a simulation toolkit for construction industry built on top of the Tecnomatix Plant Simulation-Siemens PLM Software .

It aims to simplify and accelerate the process of creating simulation models for construction project planning.

Multi Model Assembly and Analysis (M2A2) Platform

Platform for the generation and analysis of multi models - consisting of arbitrary heterogenuous, cross domain models; programatic extensibility for domain model parsers, filters and viewers; declarative extensibility for XML-based domain models; multi model query language MMQL with interpreter; TCP/IP based MMQL server; multi model viewer; reusable software components for creation of arbitrary multi-model applications

BIM Filter Toolbox

BIMfit is a modular toolbox for filtering and querying of Ifc building models.
It offers a basic set of different generic, semantic and algorithmic filter functions which can be used to build complex domain and application specific filter operations in a flexible way.
