DRASTICALLY
CUT DEVELOPMENT TIME
Heat shield performance hinges on several key factors, including position, shape, material properties, and conduction within and between material layers. Environmental effects, such as natural or forced convection also affect shield performance. RadTherm allows extremely rapid and intuitive manipulation of these parameters through the graphical user interface. Geometry is imported as surface mesh only—this keeps model size small, and allows thickness to be assigned within RadTherm. Models can be set up in minutes and parameters modified in seconds.
With the model configured, RadTherm's state-of-the-art algorithms deliver a complete solution (radiation, conduction, convection, and advection) faster than any other software package. Your heat shield performance can be improved and modified faster than ever before. For example, to redirect radiant heat, quickly change material thicknesses or add an insulation layer—all within
RadTherm's GUI. There is no need to redevelop solid geometry or recalculate view factors. Your shield design can be improved and supporting data provided to your customers.
RadTherm helps to sell
your design as well, because steady-state or transient results can be viewed and animated by your customers anywhere—using our free ViewTherm software. Your customers will have greater confidence in shield performance.
RadTherm makes the
difference in the fast-pace world of
development; rapid model setup, short
solution times, and efficient
communication of results yield faster
product development and early closure of
sales.

IMPROVE
MODEL ACCURACY
RadTherm
offers a complete
external environment. Our terrain model incorporates the full effects of solar shadowing, multiple reflections, and re-radiation of geometric features (e.g., radiation exchange between vehicle exhaust systems and asphalt road surfaces). For validation data, click the "Support" tab on our

ILLUSTRATE
SHIELD VALUE
Quickly demonstrate improved thermal
comfort and safety around heat
sources: the model above was
constructed and solved by a novice
RadTherm user in a few hours, clearly
illustrating the benefits of a
single-layer heat shield. "What
if" design questions are answered
quickly and with minimal effort. If
your team needs immediate model
results, ThermoAnalytics offers
contractual modeling and consulting
services. We can quickly deliver
contract models and/or analysis. |

Import Your Surface Mesh Geometry
Import your surface mesh from your CAD system. RadTherm can directly read meshes from Autocad (DXF), Rhino3D, Sterolithography (STL), Nastran, Patran, Wavefront (OBJ), or Digital Elevation Maps (DEM). If you have CFD data available from Fluent or STAR-CD, you can import convection coefficient and film temperatures with your geometry. For further information about integrating RadTherm with CFD, review our Technical Bulletins #320 and
#330.
