Material setting

Recommended Posts

Hi,

I want to simulate time-dependant car cabin cool-down. However, how can I setting material for different surface?
From my study, only geometry volume model can be specify the material..

Please advice.
Thank You

Kindly refer to following sections of AcuSolve-Command-Reference-Manual.pdf in your installation folder\acusolve\win64\doc\
Global commands > Radiation
Material Model Commands > Emmisivity Model

You could specify emmisivity for different surfaces to achieve your modeling goals.

Hi patil,

so thats mean each surfaces only need to define the emissivity model and solar radiation model?
And, what about material properties such as specific heat (Cp), heat conductivity coefficeint and density?

Have you checked the "Workshop10 – Modeling of Automobile Cabin using Solar and Enclosure Radiation" ?

http://training.altairuniversity.com/analysis/cfd/cfd-acusolve-workshops/

The workshop should answer most of the above queries.

Anyways, materials (air) properties are required for CFD simulations and AcuSolve is no exception. Material properties would have to be defined and assigned to appropriate volumes .
Emmisivity model need to be defined for surfaces.
