wcj1n18 is on a distinguished road
Hello,

Is there a list of variables in non-field function form that can be used in a UDF? E.g. the DFBI contact example in the manual creates variables like...

ucarg(calculateForce, "Point", "BodyPosition", sizeof(CoordReal[3]));

This "BodyPosition" has no "$" so we know it's not a field function and is in "Point" form. There must be equivalents for body velocity, force, moment , angular velocity but I cannot find a list of these variables?

I cannot use a field function because the DFBI contact UDF function has type "PointSetProfile" and the manual says "Field function arguments are always arrays of cell or face values, even when the fundamental data that they represent is a single value" and I get an error "User function: Calculate Force, argument: $BodyVelocityReport, type: Cell cannot be evaluated on a point set: DFBI Point Set [User Defined 1]. Please check settings of body coupling", hence arguments cannot be of type cell/ face when the function is "PointSetProfile", hence I cannot use field functions but there must be an alternative?

Hope this makes sense.

Thanks for any help you can provide

Will

P.S. As an alternative, is it possible for me to have the output contact force in "cell"/ "face" form, rather than "Point". This would then mean I can call field functions to my heart's content
