Methods and systems for identifying, filtering and classifying contact-pairs
A model (e.g., mechanical computer-aided design (MCAD) model) representing an assembly is displayed in a graphical user interface (GUI). The assembly contains at least a first body and a second body. The physics type of the model is determined in response to an assignment of a physics condition to the first body and/or the second body. Contact-pairs are detected in the model according to the determined physics type. The GUI is updated to indicate where the contact-pairs are located in the model for revision of the contact-pairs. Markers are shown in the GUI to represent corresponding contact-pairs. Markers are logically separated from bodies and faces in the model. The revision of the contact-pairs can be managed with a filtering mechanism either by bodies/faces or by markers.
1. A computer-implemented method comprising:
displaying a model representing an assembly to a user in a graphical user interface (GUI), the assembly having a first body and a second body;
receiving an assignment of a physics condition to the first body and/or the second body as input from the user, and determining a physics type of the first body and/or the second body in response to the assignment of a physics condition;
detecting one or more potential contact-pairs between the first body and the second body according to the determined physics type;
for each of the one or more potential contact-pairs, automatically creating a default contact-pair between the first body and the second body based on that potential contact-pair, wherein the default contact-pair is associated with a default contact type;
updating the GUI to indicate where each default contact-pair is located in the model with a visual marker, wherein the visual marker for each default contact-pair is configured to be selectable by the user to review that default contact-pair;
providing a contact review pane via the GUI that comprises:
a summary of all remaining default contact-pairs still associated with the model;
a first interface element configured to be selectable by the user to convert a selected default contact-pair into a confirmed contact-pair having a same contact type as the default contact type;
a second interface element configured be selectable by the user to convert the selected default contact-pair into an overridden contact-pair having a different contact type from the default contact type; and
a third interface element configured to be selectable by the user to remove the selected default contact-pair from the model.
2. The method of claim 1 , wherein the physics condition is assigned to a portion of the first body and/or the second body, the method further comprising: presenting a set of user interface elements in the GUI, the set of user interface elements respectively indicating separate possible physics conditions for the portion of the first body and/or the second body, wherein the physics condition is assigned via a selection of the set of user interface elements.
3. The method of claim 2 , wherein the physics condition indicates a boundary condition applied to the portion of the first body and/or the second body.
4. The method of claim 1 , wherein the physics condition belongs to a set of possible physics conditions comprising three or more of support, force, pressure, displacement, moment, mass, bearing load, bolt preload, contact, and joint, wherein the physics type belongs to a set of possible physics types, wherein the set of possible physics conditions and the set of possible physics types are related according to a configured logic, and wherein the determination of the physics type is based on the configured logic.
5. The method of claim 4 , wherein the set of possible physics types include a structural type, wherein the set of possible physics conditions include a support condition or a force condition, and wherein the support condition or the force condition is associated with the structural type according to the configured logic.
6. The method of claim 1 , wherein the contact review pane is provided in response to the user selecting any visual marker to review the associated default contact-pair.
7. The method of claim 1 , wherein the detecting the one or more potential contact-pairs further comprises: determining whether the first body and the second body are located within a predefined proximity.
8. The method of claim 1 , further comprising: receiving a user selection of the first body and/or the second body via the GUI.
9. The method of claim 8 , wherein the first body includes a face, the method further comprising:
identifying one or more default contact-pairs associated with the face of the first body; and
updating the GUI to:
indicate the visual marker for the identified one or more default contact-pairs associated with the face of the first body; and
omit the visual marker for any default contact-pairs not associated with the face of the first body.
10. The method of claim 1 , wherein the default contact type is a permanently bonded contact type and the different contact type is a sliding contact type.
