These ParaView resources are often used by CFD analysts: Calculator filters; Connectivity filter; Gradient filter's option to compute Vorticity and Q Criterion

According to what I understood it is better to use Q criterion or lambda-2 directly by CFD-post or by custum field function in Fluent ,,,

The widely used Q criterion for. Turbulent Flow Simulations (IFDT) is a new prototype visualization and CFD data The volume rendered solution is colored by Q-Criterion and the transfer 26 Sep 2013 While RANS models are indeed the workhorse for industrial CFD Difference in isosurface of Q-criterion between RANS (left) and SRS (right) skills and knowledge of CFD and transition modeling have proved integral to this 5.21 Isosurfaces of the Q-criterion = 0.00009 using AFT2019b on the S-76 10 Jul 2018 Q: Calculates the second invariant of the velocity gradient tensor.

24 Jan 2016 Using paraview to visualise vorticity (Lambda2, vorticity, Q-Criterion) use the advanced option of 'Gradient' filter to calculate vorticity, Q-Criterion. FreeCAD 0.17 + OpenFOAM CFD module now works on wind

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.

The Big_X for me has rows at different snapshots and columns as the velocity magnitude at all points in a small 3D domain. I successfully ran this code but not sure how to use the output to make contour plots or Q-criterion.

I have read online that Ansys is more robust, but you have to program UDF in C, whereas Comsol is simpler to use but less powerful per se. https://www.google.co.uk/search?q=lambda+2-criterion&hl=en&source=lnms&sa=X&ei=jda8UvvYGYexhAe69IH4Ag&ved=0CAYQ_AUoAA&biw=1920&bih=989&dpr=1#hl=en&q=lambda+2-criterion The Big_X for me has rows at different snapshots and columns as the velocity magnitude at all points in a small 3D domain. I successfully ran this code but not sure how to use the output to make contour plots or Q-criterion.

In OpenFOAM version 4.0, the ‘non-GUI’ post-processing tools have been unified within a single command line interface (CLI). Post-processing functionality includes data processing, sampling (e.g. probes, graph plotting) visualisation, case control and run-time I/O. Functionality can be executed by: Programming CFD: OpenFOAM programming that utilizes the unlimited flexibility of open source software. Developing maintainable CFD tools using OpenFOAM coding standards with C++. From the leaders of the OpenFOAM project and creator of OpenFOAM. 100% open source. 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.
