Finite Element Analysis (FEA) Videos
A model with line bodies that represent beams can have static structural analysis followed by eigenvalue buckling analysis, important for safety.
Multiple line bodies cannot have multiple end releases at a shared vertex. To treat the ends of beams as released in all rotations at a shared vertex when those beams are in a single line body, converting the BEAM188 elements of the line body into LINK180 elements can provide a workaround.
This video illustrates creating an AVZ file from an ANSYS Workbench Mechanical result, so that the file can be sent to customers or others who do not have ANSYS software.
The end of a 3D solid pipe (or nozzle) model is sometimes loaded with specified forces and moments, or by connection to the end of 1D piping elements in a larger FEA model. A pipe end face can be loaded from a remote point at the centroid of the pipe section.
A user may want to solve a very large model with multiple load steps. A restart can work from the end of one of the load steps to then consider a different loading history for subsequent load steps, saving the time required to run the load steps prior to the restart.
Users sometimes want to add some APDL processing commands to an ANSYS Workbench Mechanical model that has already been solved. This video illustrates adding APDL commands after solving, and seeing the results of those commands.
There is an ACT object on the ANSYS customer portal that can be used for element birth and death in Workbench Mechanical. This video tutorial presents a method that uses simple APDL Commands Objects to kill a spring element, and to bring it back to life, at selected load steps during an analysis.
This video illustrates using a free ACT object to obtain direct thermal-structural coupling, letting elements carry both thermal and displacement degrees of freedom.
A thermal analysis may be run in anticipation of a coupled structural analysis with bodies that are to be joined by a joint or other connection. Joints do not support heat transfer. This video illustrates two ways to include heat transfer between faces that are separated by a gap.
A Workbench Mechanical model was created with two independent beams that have coincident vertices where they can be joined. In this video we illustrate a general joint between the two coincident vertices, and control which joint degrees of freedom are set to be free.
Recent versions of ANSYS Workbench Mechanical include detection of contact between line bodies and faces. This video reviews details of a model that detects nonlinear contact between a circular line body, and the face of a solid cylinder, and the settings that make the contact work in the simulation.
A two-dimensional ANSYS Workbench Mechanical finite element model with bolt pretensioning is reviewed. The need for a user-defined coordinate system that defines where the search to cut a bolt in two is described, with its X-axis in the direction in which the bolt tightening takes place.
