Quadratic Triangle Mesh Generator
Quadratic Triangle Mesh Generator
(OP)
Hello Dear Engineers.
I need to generate a quadratic triangle mesh.
Anyone know some freetool like a executable or fortran code available on Internet?
Thank you very much

Do you know another tool?

That is, does the optimum 6 node triangle have straight edges anyway?

RE: Quadratic Triangle Mesh Generator
I just need a simple mesh, doesnt matter the geometry of the edges, just need a good quality mesh. 3 nodes generator exist a lot of programs but 6 nodes i didnt find.

Can you explain in more detail what you see as being a problem here?

RE: Quadratic Triangle Mesh Generator
If the generator produce a linear triangle and the put the other nodes in the middle of the element, the generator are duplicating the number the nodes and it can produce to much nodes that my program will spend to much time to solve.
RE: Quadratic Triangle Mesh Generator
any good pre-processor will understand that there is an adjacent element with a similar mid-side node and it should apply the same node to both elements.
else you can "equivalence" the nodes (co-incident nodes check) and get the two nodes merged, and then if you Really want you can condense the node numbering (so you don't have gaps).
"I just need a mesh generator for 2D quadratic triangle mesh, like a open source." ... ahhh ! you're trying to "kluge" together your own pre-processor ... yeah, sorry, can't help you with that. but if you have a triangle mesher, then the mid-sides are easily calculated, and the co-incident nodes easily determined (I mean, each side will be on one or two elements).
