How to vary the meshing size automatically and smoothly?
Posted: Thu Nov 11, 2021 12:27 pm
Hello,
I initially developed a model with a constant meshing throughout the NURBS surfaces. However, I needed to densify the meshing within the region where the high deformability occurs. Therefore, I assigned to the corresponding NURBS small size of meshing. To achive a smooth transition among the dense meshing (0.5) and the coarse one (2), I added to the model additional Nurbs surfaces in order to assign increasing meshing dimensions (0.75, 1....). In this way, I tried to ensure that the aspect ratio among the neighbouring elements would be acceptable.
I wonder if there is an automatic way through GID, to achieve a smooth transition in elements sizes rather than introducing additional surfaces and assigning manually the size of the meshing. Please note that I cannot use the option of structured meshing as my geometry is a bit complicated.
Thank you very much.
