Thank you for your previous answer about zero jacobian.
Now, I got another problem;;
I made 2 *.geo files.
file 1 : 3d_test_2.geo
file 2 : takeda_model3_3d.geo
First one can accept advanced mesh options "Optimize quality of
tetrahedra", "Optimize quality of tetrahedra with Netgen"
But second one generates error message that "run time error"
You can know if you run the file 2.
My question is, why this error message occurred? Although file 2 is
somewhat complicated one compare with file 1, basic structure and order
is same as file 1. So, I couldn't understand why this message was occurred.
And second question is what is the difference between option "Optimize
quality of tetrahedra" and option "Optimize quality of tetrahedra with
Netgen"?
Indeed, the mesh generated by the 3D Delaunay leads to elements that are
completely flat, which the optimizers cannot recover... We will keep
your file in our bug database.
Two solutions until we fix the problem:
1) Use the Frontal 3D algo, which works fine on your example
2) Extrude your mesh (cf. the "Layer" command in Extrude)
I attached both file 1 and file 2.
Thank you for reading.
