1.2.1 Q-criterion The Q-criterion is one of the most commonly used vortex identification methods[2-3]. It borrows the definition directly from the second invariant of velocity gradient tensor. For incompressible flow, the trace of u is 0. Thus Q can be simplified as 1 22 2 Q Ω S (7) where the notation stands for Frobenius norm of a tensor.

* q_r: radiative heat flux. * T_b: temperature on the boundary. Often we start with a high epsilon and gradually decrease it during the training, known as “epsilon annealing”. The full code of QLearningPolicy is available here.. Deep Q-Network. Deep Q-network is a seminal piece of work to make the training of Q-learning more stable and more data-efficient, when the Q value is approximated with a nonlinear function.

If we are running the PIMPLE solver without any keywords, the solver operatings in the so called PISO mode. Therefore, we need to fulfill the stability criterion Co < 1. Based on the fact that we set CoMax to 3, this is the reason why the simulation will blow up. OpenFOAM outputs the operating mode of the solver after starting the solver:

Q If the field entry is set to a value other than U, the default name becomes . Q() This can be overridden using the result entry. Sample output The isosurface of Q-criterion you should plot is "some positive number that you like" Q-criterion is also dimensional in its pure definition, so one type of flow you take Q=1 and another type of flow you might take Q = 1000.
