Main features

  • Easy creation of 3D bodies with holes, 3D views with different angles

  • STL files import. You can import the body shape from STL files created by CAD/CAM or other 3Dsoftware

  • Automatic net determination for heat transfer analysis, normally between 50,000 and 1,000,000 points

  • User-defined points with fixed temperature and internal heat sources

  • Two convection fronts and two radiation fronts

  • Dynamic transient process analysis

  • Various modes 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 temperature gradient

  • Material parameters may be uniform or different in different parts of the body

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.

EXAMPLE

The following 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 degree.

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.
