Is there a way to determine the volume of an element following a structural solve? The postprocessor simply reports the volume of the elements as they were meshed, before deformation.
Yes, alhtough this is not something that is directly available in the ANSYS postprocessor. There is however, a way to do this using the UPCOORD command. Using the UPCOORD command in a subsequent solve, the new displacements of the nodes will be retained and the new volume can be reported in postprocessing. Users should investigate the UPCOORD command before use it to be sure they understand what changes may take place to the model. Below is a simple one element model containing an element of unit volume under pressure and showing the use of the command to report the new volume.
