Ansys EmployeeHello,
Go to Materials in Outline View. Here, right click on the Solid or Fluid bar and click New. Now, you will see three options: Fluent Database, GRANTA MDS and User defined. Click on any of them which you want and you can see the list of materials you need.

Subscriberwhat i needed was to
define new species ,for the following data
[biochemical parametrs]
biochemical diffusion coefficient (m^2/s)
thrombin 6.47e-10
fibrinogen 3.10e-10
fibrin 2.47e-10[Reaction kinetics parameters]
parameter values unit
Kcat 3.540 min^-1
Km 3.160 nMol -

SubscriberA
material > fluid or solid> there is no mass diffusivity ( diffusion coefficient (m^2/s))
so i tried
material > mixture> mass diffusivity ( diffusion coefficient (m^2/s))
but there are other parameters too coming, other than whats needed. i dont have those data. i am doing with reference to a research paper. the paper doesnt specifies those. -

Ansys EmployeeHello,
I would suggest you to option A. If you do not know the other property values, you could use recommended or default values in the Ansys guide.
