CFD-ACE+ Tips [more...]Specifying Body forces on Macroparticles via User Subroutine
Multiphase
flows occurring in various scientific and engineering fields and application
areas like biotechnology, bio-defense, micro-fluidics, chemical processing and
environmental research etc., can be modeled using the Macroparticle module in CFD-ACE+.
CFD-FASTRAN Tips [more...]Avoiding Chimera Errors in CFD-FASTRAN
This note discusses a
common error encountered by users when trying chimera meshes in CFD-FASTRAN.
Such errors are easy
to avoid and hopefully this note will assist you.
CFD-GEOM Tips [more...]Model Inversion in CFD-GEOM V2008.2
With the new CAD model import options in CFD-GEOM, it is now easier
than ever to read your solid models into CFD-GEOM. Once the model is
in CFD-GEOM, you have the solid representation of the part but in many
cases the fluid, or negative space, in the CAD model is of importance
and the area which needs to be discretized (i.e. meshed).
CFD-VisCART Tips [more...]Grouping of Geometry Surfaces in CFD-VisCART V2008.0
In CFD-VisCART V2008.0, a new Group/Ungroup capability has been added for geometry surfaces. Grouping is
useful for collecting multiple geometries having the same meshing parameters and/or boundary conditions.
CFD-VIEW Tips [more...]Getting Average Quantities in CFD-VIEW V2008.2
Many times
post processing results requires computing average quantities of variables over a
surface or volume. CFD-VIEW V2008.2 made it easy by adding three new calculator functions
under the ‘Miscellaneous’ function category as shown in Figure 1.
CFD-CADalyzer Tips [more...]Inverting Models in CFD-CADalyzer
Computational Fluid Dynamics (CFD) requires the discretization of a
geometry bounded by it's wetted surfaces. In CAD, the solid parts are
created without the corresponding fluid volumes, i.e. negative space.
CFD-TOPO Tips [more...]CFD-ACE+ and CFD-TOPO Coupling
There is a growing demand and challenge in different
industries, especially semiconductor and MEMS areas,
to have increased wafer size with reduced feature
size, i.e. high quality process uniformity.
General Tips [more...]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.
