Dear Dr. Khaled Al-Farhany,

Technically speaking, it is YES for FLUENT. However, everything will depend on the precise target & the type of your problem!! For instance, you can take a look at the "Solidification/Melting Module of Fluent" where the effect of porous of media is IMPLICITlY added as the SOURCE TERM in the momentum transport for Solidification/Melting problems.

Anyway, I am recommending you again to check the THEORY and USER MANUAL of FLUENT for further details.

Additionally, a link on "Porous Media Conditions" in Fluent is given below:

"http://www.afs.enea.it/project/neptunius/docs/fluent/html/ug/node233.htm".

Please check it, and I hope that you will find some hints for your target.

Khaled Al-Farhany

Dear Dr Akter Hossain

many thanks for reply. FLUENT easy to use but difficult to believe of his results.

Many thanks again, I will do my best with it or go to COMSOL

Regabds

In my understanding, all commercial Softwares are same in terms of the accuracy of results !! The potential users are required to verify the results based on the "Physical Laws" and the "Experimental Result" if it is available. It is simply because USERS are not allowed to check the "Numerical Coding" directly in case of the Commercial Softwares! Anyway, all the best for your work!

Thanks for your wishes

In COMSOL Multiphysics it is very easy. For example, when you use Brinkman-Darcy model, the Darcy terms can be added to the components of the VOLUME force.

So you agree with me, they using just fluid flow model and then added the effects of Darcy or Darcy-Brinkman as Fraction terms only... i mean (they not use the Brinkman model of COMSOL).
