The ElmerModel manual says this
Material mat id
The material section is used to give the material parameter values. The following material parameters
may be set in Navier equations.
Rayleigh Damping Logical
Apply rayleig damping.
Rayleigh Damping Alpha Real
Rayleigh Damping Beta Real
The parameters of Rayleigh damping.

Rayleigh Damping
Re: Rayleigh Damping
Hi,
it sould work if you write
Rayleigh damping = Logical true
There is a SOLVER.KEYWORDS file in the lib directory of the Elmer installation. The "Rayleigh damping" keyword is not listed there, so Elmer doesn't know that it is logical.
HTH,
Matthias
