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
Yes, material is a volume depenedent property and can be assigned to a volume.What could be the reason for assigning material to a surface? Is it for radiation model?
Hi Patil,
Yes, it is for radiation model.
Regards
Kindly refer to following sections of AcuSolve-Command-Reference-Manual.pdf in your installation folder\acusolve\win64\doc\Global commands > RadiationMaterial 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.
