Simple free 2D FE triangle mesh generator?
(OP)
FE Newbie here.
I am looking for a simple tool to help me do 2D triangle mesh generation ?
The geometry I am interested in modeling is several sets of concentric circles adjacent to other sets (electric field model of several adjacent wires with insulation).
I checked the FAQ. Didn't see much there.
I searched the old threads and found one old thread where the original poster was looking for a very simlar thing
thread727-137588: FEM 2-D mesh generator?
Looks like the one's mentioned were calculix, z88, and some preprocessor for Franc2D
Since the thread is old, I just wanted to check if these are still good choices (or any other opinions or comments)
Thanks in advance

All I need is a relatively easy way to generate node coordinates and list of which 3 nodes go with each triangle element.

I used to write them myself, back in the days when I got the boring jobs. We had to write them by hand because the element numbering defined the solution order and hence the wavefront.
An axisymmetric 2D mesh is going to be pretty straightforward, Excel might even be a good tool for it. You could use a robust node numbering methodology that generates telephone number length node numbers for each element, and then merge coincident nodes and do a renumber at the end.
