Multiple 'Define' macros to be hooked into one location

wcj1n18 · February 28, 2021, 12:25

Hi,

I would like to use both DEFINE_SDOF_PROPERTIES and DEFINE_CG_MOTION for just one SDOF object. Problem is, they should both be hooked into the same location (Dynamic Mesh - Dynamic Mesh Zones - SIX DOF UDF/ Properties). How can I assign a SDOF property and a CG motion to one SDOF object?

So far, I have put both of the DEFINE macros in one .c file and compiled with no problems. Problem is when I go into (Dynamic Mesh - Dynamic Mesh Zones - SIX DOF UDF/ Properties), it gives me the option of assigning one of the DEFINE macros to the object but not both?

Is this not possible or am I missing something here?

Thank you

PS. I have one rather more long-winded back up plan, however, simply doing it as described above would make things easier.

I'm working on something that involves a similar problem. Were you able to solve this particular problem? If you did then please let me know xx

in define_sdof macro, dt_vel_cg option can be used to define motion which is intended in define_cg_motion.
both macro have certain difference.cg_motion imposes the motion which is irrelevant of 6dof equation and associated forces.
