| Pre-Processor is the part
of the software that prepares the data for the solver, creates shapes, generates meshes and
defines boundary conditions. HEAT
Designer's Pre-processor is equipped with a GUI specialized for thermal design of electronics. |
|
Wizard Tools |
|
The solver in HEAT Designer uses an interactive Wizard
that permits specification of the calculation parameters
that control the calculation convergence rate.
HEAT Designer can also automatically set the calculation
parameters by specifying the target object of the
calculation. |
| Mesh Generation |
The structured grid in HEAT Designer is simple and easy
to use. HEAT Designer mesh generation is
practically automatic and suitable for complex
geometries. The multi-block function offers the
capability to locally refine the grids in a particular
area. Multi-block can be used to locally increase
grid resolution in high gradient regions.
 
A new meshing capability in HEAT Designer is called
Connect Block. Connect Block permits connecting
groups of multi-blocks together. This is
especially useful when meshing objects that are located
very close to one another, a common situation on an
electronics circuit board. Locally refining grid
resolution only where needed also reduces the memory
needs and computation time while maintaining high
accuracy.
The Pre-Processor in HEAT Designer features a macro
function. The macro function can construct a
special menu to automate a series of operations that are
often repeated. |
| Deformation Function (rectangular approximation) |
There are cases that mesh is not generated uniformly or as you want it to be with the use of automatic mesh generation.
To prevent such nonuniform mesh generation and false recognition of the original geometry, the geometry can be converted into shapes with staircase pattern prior to mesh
generation. This function enables you to fix mesh location and keep surface area and volume after meshing.
 |
| Condition Setting |
HEAT Designer focuses on simulating air flow and heat transfer, so that condition setting can be easily done in
accordance with wizard.
HEAT Designer is based on scSTREAM, multi purpose thermal fluid analysis system with structured mesh, and they basically share the same wizard. Therefore, you can smoothly move
up to scSTREAM wizard if you want to use more functions of
scSTREAM.
  |
| CAD Import |
Heat Designer can import 3D CAD data (e.g. Palasolid(X_T),STEP(.stp),STL) and IDF data, which is used in electronic
board designing as a model geometry. The useful functions such as the simplification of complicated geometry, the batch deletion by size and the click-designated deletion help
you to utilize the CAD data, especially for analysis of electronics that may include complex component, too little parts and/or too many parts.
 　
Initial wizard also enables placement of parts and assembly, scale conversion and creation of various computational domain according to what kind of simulation you would like
to do. |
| CSV file |
An user usually defines material property, but it would be too much work for a data that contains hundreds or thousands
of parts and it would increase the chance of making a mistake. As a solution to such troubles, HEAT Designer is implemented with CSV file interface which enables you to create
parts data in an Excel format with part name, material property heat flux and so on to set those data at once . In addition, you can ask somebody else to prepare those data by
giving the excel file since it does not require a license, and you can reduce your workload.
