TetWild not converging

[csverma610]

Hello,

I have been trying to use TetWild but it seems with the default values but it never converges. It keeps churning messages.

Am I doing something wrong?

Hi,

TetWild does not guarantee convergence (please refer to our paper). As far as I know, few mesh optimization algorithms have the guarantee to improving mesh quality in a certain specific quality measure to a given bound, like Delaunay refinement. But the output of Delaunay refinement can still contain poorly shaped elements, like slivers.

TetWild would stop when max optimization iterations are reached.

Please try using "--stage 2", which would take longer time but may produce higher quality output.

@csverma610 Do you have an example that you can share? Thanks!

1. can i get a topologically correct mesh ( poor geometric poor quality) mesh quickly?
2. is it poosible to get a good surface mesh without generating tet mesh?
3. it seems in one of the header files, you used tbb.h but where it is used? my system shows only one thread running.

thanks

1. can i get a topologically correct mesh ( poor geometric poor quality) mesh quickly? Please use a larger filter energy.

2. is it poosible to get a good surface mesh without generating tet mesh? No.

3. it seems in one of the header files, you used tbb.h but where it is used? my system shows only one thread running. We are not using tbb. Are you using the newest code?
