Output Type
Currently, the available types of output variables are listed as follows.
Please note, in principle, it is possible to define any types on any recorders, but if the target recorder does not
support the type, trivial/empty values will be returned. If saving recorder does not create any files on the disk,
meaning that the output type is not available for the target object. For example, recording strain/stress E/S
values of any nodes is not possible and will lead to no output.
The complete support list is still under development. In principle, basic types such as displacement/velocity/acceleration are available for nodes. For elemental response, generally stress/strain and their components are available. Certain elements only support some output types. Please feel free to open an issue if you need more information.
