Siegel Schleimer Ingénieurs-conseils Becomes COMSOL Certified Consultant

ZOETERMEER, Netherlands (March 24, 2011) – COMSOL developer of the industry-leading COMSOL Multiphysics modeling and simulation environment for scientists and engineers, announces that Siegel Schleimer Ingénieurs-conseils s.à r.l. has become its first certified consultant in Europe's BeNeLux region. As a COMSOL Certified Consultant, Siegel Schleimer Ingénieurs-conseils offers its clients a broad range of multiphysics expertise in areas as diverse as single fuel cell, fuel cell stack, chemical reaction technology, and battery modeling and simulation. The company also provides in-depth expertise simulating coupled physics phenomena in and around homes, large buildings, and office complexes including the design and layout of energy-efficient heating, ventilation, air conditioning (HVAC) systems.

“We’re delighted to partner with Siegel Schleimer Ingénieurs-conseils,” says Gerard Hegemans, Director of COMSOL BV. “They extend the reach and depth of COMSOL's technologies to our growing customer base in the BeNeLux region and enable us to better serve our users in such exciting and flourishing fields as fuel cell development and energy-saving, green building design.”

Located in Mondercange, Luxembourg, Siegel Schleimer Ingénieurs-conseils s.à r.l., was founded in 2010 by Christian Siegel and Markus Schleimer. Christian Siegel has worked at the Center for Fuel Cell Technology (Zentrum für BrennstoffzellenTechnik – ZBT) in Duisburg, Germany, in the field of polymer electrolyte membrane (PEM) fuel cell research and development. In addition to his experience in experimental and theoretical fuel cells, Mr. Siegel has extensive expertise in such fuel cell and fuel cell stack-related areas of investigation as:

  • Computational fluid dynamics (free and porous media flow)
  • Integral flow-field and cell layout
  • Heat and mass transfer (heating, cooling, and tempering concepts)
  • Analysis of structural aspects (localized fluid-structural interactions)

Markus Schleimer has been an energy consultant focusing on the design and layout of energy-efficient HVAC systems for small homes, large buildings, and office complexes for more than ten years. Among the specialized skills that Mr. Schleimer brings to building simulation are:

  • Coupling of building energy simulation to computational fluid dynamics
  • Combining simple energy calculations to integral simulations
  • Layout of heating, ventilation, air conditioning, and cooling applications
  • Temperature distribution
  • Fluid-flow around buildings
  • Air pollution, moisture, and contaminant dispersion
  • Smoke and gas distribution

Siegel Schleimer Ingénieurs-conseils excels at solving large-scale finite element problems and coupling numerical analysis with engineering applications. “With COMSOL Multiphysics running on our high-performance workstations,” says Markus Schleimer, “we are able to offer unique, specialized engineering and analysis services to any private, commercial, and governmental customer needing to solve large-scale finite element problems that couple multiple physics phenomena.”

"We work closely with our high-tech clients to better define, model, mesh, and solve their multiphysics problems as well as analyze simulation results,” adds Christian Siegel. “As a certified COMSOL consultant we will provide solutions for engineers on the cutting edge of research and development into new products and new technologies for fuel cells, batteries, as well as energy efficient building environmental systems.”
