Hi i am trying to couple openFOAM with Elmer FEM solver, i am using the flow over heated plate problem as a test problem. For this tutorial, i cannot find the density of the fluid as well as the solid which are required by Elmer solver, otherwise the solver stops and does not continue. I cannot calculate the fluid density from Prandtl number because the density cancels out in equation
$$Pr = \nu / \alpha $$ , $$Pr = (\mu / \rho) / (\cp * k / \rho) $$ .
For more details about Prandtl number equation: https://en.wikipedia.org/wiki/Prandtl_number

Also in the solid i cannot calculate it because alpha(thermal diffusivity) is provided as well as k(Heat Conductivity) but the cp(Heat Capacity) is not provided which also is required by Elmer. Is there a way to access these data or calculate it.

Thanks in advance
Hisham
