 ===== 2-D Fortran CFD code for tornado-like vortices =====
-The source code is here: [[https://github.com/bfiedler/ezan/blob/main/ezan3_2025.tar.gz]]
+The source code is here: [[https://github.com/bfiedler/ezan | at github]]
+The **eza** in the name is for //easy axisymmetric//. Perhaps **n** is //new// and **3** is version?
 I believe this code is what I used as the companion axisymmetric code in {{ :tornadobox:suction_vortices_and_spiral_breakdown_in_numerical.pdf | my 2009 QJ article}}.
 It produces slightly difference results than the code for [[https://12characters.net/anim2dvort/ | axisymmetric simulations prior to 2009]], mainly because the viscosity profile was simplified for compatibility with the  [[tornadobox|3-D Fortran CFD code for tornado-like vortices]].
