COEFF_p_divV

factor to switch on and control the p*div(v) term in temperature equation

COEFF_p_divV = 1.0
Default: COEFF_p_divV = 0.0 This term is switched off by default because for incompressible flow problems it is zero. But for weakly compressible flow problems it becomes more important so that it is needed to use COEFF_p_divV > 0 for switching on this term. COEFF_p_divV = 1.0 means the term \( p \, (\nabla \cdot \mathbf{v})\) is multiplied by one, thus the temperature equation \begin{align} (\varrho \, c_v)\left(\frac{\partial T}{\partial t} + \mathbf{v} \cdot \nabla T\right) &= \nabla \cdot (\lambda \, \nabla T) - p \, (\nabla \cdot \mathbf{v}) + \Phi \end{align} is used, whereby \( \Phi\) is the dissipation function.
