Happy Holidays from ESI Group!

From everyone here at ESI Group, we would like to wish you and your family a safe and happy holiday season.

This animation shows Silane deposition onto the letters surface through chemical surface reaction using the ACE+ suite of multiphysics software from ESI. These types of surface reaction simulations are commonly used by semiconductor manufacturing engineers to improve their processing speed while insuring that they create a uniform deposition over the wafer surface. The simulation was created using the following features available in ESI’s CFD products:

Flow, Chemistry and Spray modules from CFD-ACE+
Tetrahedral volume meshing using CFD-GEOM
Visualization and animation creation with CFD-VIEW

Holiday Schedule

ESI CFD offices will be closed Dec. 24, 2009 - Jan. 3, 2010. We will have someone checking emails for emergencies, so please send emails to This e-mail address is being protected from spam bots, you need JavaScript enabled to view it if you have an emergency.

Always Make Sure You Have a Good Mesh Quality

The mesh has a great influence on the solver convergence and solution of every CFD Simulation. The user is strongly advised to check the quality of a numerical mesh.

Windows XP Service Pack 2 Issues

Windows XP with Service Pack 2 is becoming more prevalent in use. However there are a couple of issues for which you need to be aware. These issues have to do with the license manager and the display of the online help. This note gives solutions to problems that may be encountered.

Optimization using an Adjoint Method with PAM-FLOW

The CFD optimization of different car components has the potential of significantly shortening the design process (Othmer & Grahs, 2005). The adjoint method recently implemented in PAM-FLOWTM is an advanced approach which aims to compute the sensitivities of the cost function and to plug them into a gradient-based optimization algorithm.

Parametric Studies Using SimManager

Parametric studies are an important aspect of CFD analysis. Parametric studies are used to perform trend base analyses, optimize the deign of a device, and/or to study the affect of different parameters on a process (What if? type analysis).
