Cavity remeshing

Author: Vicente Mataix Ferrándiz

Kratos version: 7.1

Source files: Cavity

Case Specification

In this test case,

The following applications of Kratos are used:

This is a very simple remeshing test, where we remesh a cavity 1x1 using the distance to the center as test function.

Original.

Results

The results obtained after remeshing can be see in the following figures:

Solution

The color map of the distance:

Distance

The variation of the element size:
