Abstract

In an example embodiment, a process may calculate a fill ratio for each element in the background mesh. The process may identify partially filled elements of the background mesh based on the calculated fill ratios. The process may transform each partially filled element to an empty or filled element by identifying a node of the partially filled element and moving the identified node to a different location in the background mesh. The process may generate an updated background mesh, that includes only empty and filled elements, that may be utilized to perform one or more calculations for one or more time steps in a modeling/simulation environment to simulate a behavior of a physical material/object that may exhibit deformations.

Dependent claims

A system for modifying a mesh for a material point method that is used for geotechnical engineering, the system comprising:

an application executing on a computing device, the application configured to:
identify at least one partially filled element of the mesh that includes a plurality of elements that are connected by a plurality of nodes and further includes a plurality of material points, wherein the partially filled element includes an empty portion and a filled portion, and the at least one partially filled element is determined to be partially filled based on an area or a volume of the filled portion relative to an overall area or an overall volume of the partially filled element;
and
move a selected node, of a set of nodes that define a perimeter of the at least one partially filled element, from a first location to a second location in the mesh to generate an updated mesh,
wherein moving the selected node decreases a size of the filled portion of the at least one partially filed element and transforms the at least one partially filled element to an empty element, or
wherein moving the selected node decreases a size of the empty portion of the at least one partially filled element and transforms the partially filled element to a filled element.

A method for modifying a mesh for a material point method that is used for geotechnical engineering, the system comprising:

identifying, by an application executing on a computing device, at least one partially filled element of the mesh that includes a plurality of elements that are connected by a plurality of nodes and further includes a plurality of material points, wherein the partially filled element includes an empty portion and a filled portion, and the at least one partially filled element is determined to be partially filled based on an area or a volume of the filled portion relative to an overall area or an overall volume of the partially filled element;
and
moving, by the application, a selected node of a set of nodes that define a perimeter of the at least one partially filled element, where the selected node is moved from a first location to a second location in the mesh to generate an updated mesh,
wherein moving the selected node decreases a size of the filled portion of the at least one partially filed element and transforms the at least one partially filled element to an empty element, or
wherein moving the selected node decreases a size of the empty portion of the at least one partially filled element and transforms the partially filled element to a filled element.

One or more non-transitory computer-readable media, having stored thereon instructions that when executed by a computing device, cause the computing device to perform operations comprising:

identifying at least one partially filled element of a mesh that includes a plurality of elements that are connected by a plurality of nodes and further includes a plurality of material points, wherein the partially filled element includes an empty portion and a filled portion, and the at least one partially filled element is determined to be partially filled based on an area or a volume of the filled portion relative to an overall area or an overall volume of the partially filled element;
and
moving a selected node, of a set of nodes that define a perimeter of the at least one partially filled element, from a first location to a second location in the mesh to generate an updated mesh,
wherein moving the selected node decreases a size of the filled portion of the at least one partially filed element and transforms the at least one partially filled element to an empty element, or
wherein moving the selected node decreases a size of the empty portion of the at least one partially filled element and transforms the partially filled element to a filled element.
