However, this feature still returns strains and not opening information.
As explained in manual, you need to output the length using command:
- Code: Select all
TimeHistoryList HIST {
sg-GageName length
}
You need to subtract the initial length to get the change, though.
How can I determine the strain (or better length change) on a curved surface?
You can choose two end points on the curved surface, set Segments keyword to be the resolution you want, MARS will discretize the two end points by number of segments, then project the middle points onto the curved surface. In this case, the length of the gage is on the curved surface. This feature works in version >= 2016.9.05.
Is it possible to set a gage between two different tetlists, e.g. two loading blocks ?
No, it has to be inside the same tet list.
