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.

Threshold value
-This field triggers the mapping of the nodes. The contact algorithm uses internal fields that are named contact_field and are defined on the free surface. This field stores the contact information for each node and initially has a value of either 0 or 1. If a node of the free surface is in contact, the field value is 1, otherwise the value is 0. However, after a remeshing step, the contact_field values must be interpolated onto the newly generated mesh. 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). If a node of the free surface has a contact_field value greater than the threshold, the node is assumed to be in contact and will be mapped. The default value of the threshold is 0.8

Contact is formally described with a step function taking values 0 and 1. With the calls to adaptive meshing and the subsequent interpolation of fields, the transition stripe from non-contact to contact areas may diffuse. The threshold value is used for removing the uncertainty and assessing contact beyond the threshold. By default, the threshold is set to 0.8.
Scaling factor
-This parameter is used to determine if a point on the free surface is in the vicinity of the mold surface. The distance between the free surface point and the mold surface must be less than typical_size*scaling_factor, where typical_size is the maximum size of a face (or a segment in 2D) of the mold surface. The default value of Scaling factor is 0.6.

+Maximum Displacement Mode
+Allows you to set the method for determining the maximum displacement of surface nodes during the mapping stage of the adaptive meshing as either Program controlled or User Value. It is the upper bound of the displacement applied to nodes that are mapped onto the contact surface. By default, the value is Program Controlled. 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.
Penetration tolerance
-This parameter is used to provide a tolerance level for the distance between the free surface and the mold surface. If a point on the free surface is located inside the mold at a distance from the mold surface below this tolerance, the point will not be moved; otherwise the position of the point is corrected. 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.
