AutoFEM Analysis Non contacting bodies | |
Mode Contacting groups of bodies reflects groups of bodies not having physical contact with other bodies or groups. If the body which does not contact the others is characterized by insufficient boundary conditions (e.g., it is not fixed in the space in the case of static analysis), an algebraic system of equations may prove to be degenerative, and the process of calculations may stop. Therefore, in some cases, the presence of independent groups of bodies in the study can indicate incorrectness of the problem setting. The diagnostic mode shows all independent groups of objects and has two additional options. On default, the system shows fully separated groups of solids or surfaces which have no any common points In the second case, there are two button right from the list which allow the user exclude some bodies from the calculation or re-include previously excluded parts. Bear in mind, that excluded parts are not deleted from the study! They are remaining on the list of study objects, though it is impossible to apply boundary conditions to them and they are not visible in the Pre- or Post-processor window.
Non-contacting groups of bodies in the study. Buttons on the left allow exclude any object from the calculation.
