determination for heat transfer analysis, normally between
50,000 and 1,000,000 points
points with fixed temperature and internal heat sources
convection fronts and two radiation fronts
transient process analysis
of graphical results display: temperature at sections by
planes, 3D view of the whole body, plots of temperature changes
as function of time, display for both temperatur and
parameters may be uniform or different in different parts of
It takes few
minutes to create an arbitrary or axisymmetrical body shape with
various holes in it. Then, the program processes the model
geometry. After this, you must define the material parameters
and boundary conditions like convection or radiation fronts,
fixed temperature points, initial temperature etc. Then, the
heat transfer analysis starts. The process is monitored during
the process and you can see the propagation of temperature in a
default section of the body.
figure shows the 3D view of the contours that describe a body
with a hole in it. The grey lines correspond to the main body
and the yellow/red ones are the "holes". The parts of
the holes that ore outside the main body are irrelevant. The
"hole" in the main body is determined by the
intersection of the hole shape and the main body. It takes less
than 5 minutes to create shape like this.
You can see the
body you have created as a solid, as shows the following figure.
Suppose that the
initial temperature of the body is equal to 22 degree C, and
that a flow of hot water at 90 degree passes through the canal
(a hole) of the main body. The body is made of steel. The
environment temperature is equal to zero degree, and all the
boundary of the body (except the cillindrical hole) is the
convection front, the body being cooled by an air flow. The
following figure shows the same 3D view with the temperature
reached after about 20 seconds, marked by different colors The
yellow corresponds to about 60 degree, dark blue is about 20
The results can be
seen from different angles and in different sections of the
body. Below you can see the section by a plane perpendicular to
the maind body axis, near to the right end of it.
