I conducted inverse dynamics analysis through MoCapModel, and asked whether the force derived from AnyFE2Abq plug-in was generated at a certain moment or at all moments in the process of movement, and whether the force at a certain moment could be obtained through Abaqus software.
The AnyFE2Abq export should be the forces over time, is that not what your export contains?
I'm not sure what you mean by
could you elaborate on that?
The output file generated by AnyMechOutputFileForceExport contains everything, the entire dynamic picture of the modelled system. When applying AnyFE2Abq to the output data - you generate an Abaqus input deck, which should have loading tables ( force/moment over time using *AMPLITUDE keyword). You can specify a particular moment in time in your Abaqus analysis, and, if everything is done right, it should get you what you need.
