Use Size Field

+

Determine whether or not you want to use size fields when generating the volume mesh. Generating the volume mesh using size fields can require additional memory as you increase the number of processing cores. This is because the size field is replicated for each core as the size field is not properly distributed. When using size fields, you are limited by the size of the machine. When not using size fields, however, you require less memory and you can use a higher number of cores with limited RAM, leading to a faster mesh generation.

Specify the number of times a primitive element (that is, an element of the initial mesh, as created in the mesh generator) can be subdivided recursively. Adaptive meshing involves up to M levels of element subdivision, by default M equals 3. Depending on the conditions to satisfy, elements are recursively split into sub-elements. With each level of subdivision, the local element density increases by a factor up to 4: three levels of subdivision potentially increase the number of elements by a factor up to 64. There is never more than one level of subdivision between adjacent elements. Unless conformalization is asked, quads are usually subdivided into quads; tris are subdivided into tris. However, other subdivisions are possible when the aspect ratio and/or the skewness requires it.

After this interpolation, the contact_field values are no longer limited to being either 0 or 1, but can be intermediate values (for example, 0.3).

Contact is formally described with a step function taking values 0 and 1.

The threshold value is used for removing the uncertainty and assessing contact beyond the threshold. By default, the threshold is set to 0.8.

You can change this and specify a User Value when prompted.

Maximum displacement

User Displacement

In order to avoid highly distorted elements in the layer of elements adjacent to the free surface, the displacement of the mapped nodes is limited to this value. A good practice is to define the maximum displacement as 10 to 25 percent of the minimum element size imposed in the adaptive meshing setup. The default value is calculated from the typical mesh size.

Three options are available: a value of max displacement sets the penetration tolerance to be equivalent to the maximum displacement; a value of penetration accuracy sets the penetration tolerance to be equivalent to the minimum of the penetration accuracies; a value of user input allows you to provide your own value for the tolerance.

For the curvature method, this value is dimensionless, and its default value is 0.2. This value should lead to almost 30 elements to mesh a circle. Sufficiently close to the contact mold, element size will be a given fraction of the local radius of curvature, unless it hits the minimum size as lower bound. The selected default value of 0.2 suggests that about 5 fluid elements can be created for matching 1 radian (57 degrees) of a curved mold portion.

Tolerance

help text for filtering threshold on fluid fraction

Some variations of the fluid fraction in the wet zone (far from interface with dry zone) may be filtered with this parameter: all variations higher than this threshold will be smoothed. The variations smaller than the threshold will be unchanged. For example, with a threshold of 0.1, if the local value of the Fluid Fraction is 0.95 (instead of 1.0 ideally), then the variation = 0.05 (= 1.0 - 0.95) is below the threshold. Consequently, the value is unchanged. However, for a value of 0.89 (instead of 1.0 ideally), then the variation = 0.11 (= 1.0 - 0.89) is above the threshold. Consequently, the value will be filtered (value reset to 1.0).
