hi anindya, you certainly have the definition of that q criterion which is based on velocity gradient. Fluent do not provide it directly,i mean you have to compose it from computed velocity gradient as a custom field function. for that: define>custom field function and type the name of the criterion "q" for example. you will be then able to visualize the q value on a specified surface on the

criteria that remain invariant under coordinate changes of the form y=Qx + at, where Q is a proper orthogonal tensor and a is a constant velocity vector. For a three-dimensional smooth velocity ﬁeld v(x,t), available Galilean-invariant vortex criteria use the velocity gradient decomposition ∇v = S+Ω, (1.1) where S= 1 2

It uses three criteria, assigning one point for low blood pressure (SBP≤100 mmHg), high respiratory rate (≥22 breaths per min), or altered mentation (Glasgow coma scale15). READ MORE.

This integration makes the calculations faster, more memory efficient and easier to use. The Q criterion is written as Q = 0.5*(vorticity 2 - strain rate 2) > 0 meaning relative dominance of the rotational component over the stretching component in deformation of a fluid element.

you will be then able to visualize the q value on a specified surface on the 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.

In this video we’ll show you how to calculate Q-Criterion, plot the results, and compare the performance of Plot3D and SZL file formats for this work. In this example, we are using the final time-step of a transient simulation of a wind turbine. Q-Criterion is an important calculation used to identify vortices.

In Tecplot 360 2020 R2, we’ve added a new capability to reference variables by name. This is important because sometimes you may have two simulation runs where one … The Q s-criterion is objective and can be turned into a mathematically exact vortex deﬁnition for two-dimensional ﬂows.
