Feedback for "fix1"

fb_fix1(o, n, i, description)

• o list of objects
• n names field
• i index of fix1 object
• description string with Text to identify the object for the user

fb_fix1_name(o, n, i)

• o list of objects
• n names field
• i index of fix1 object

These functions provide Feedback for Free Body Diagrams.

"fix1" is a unidirectional support. It is to be replaced by a single reaction force.

Checks done by the fb_fix1():

• Is the object really of type "fix1" (just for developers)?
• Is the object deactivated?
• Has meclib found any reactions by proximity check?
• Is there exactly one reaction?
• Is the reaction of type "force" as opposed to "moment"?
• Is the reaction normal to the direction of unconstrained motion?

Checks done by the fb_fix1_name():

• Is the name a single character?
• Does the name of the reaction match the name of the support point?

Two-node PRT

Feedback variables:

obj: stackjson_parse(objects);
[text, isOK]: fb_fix1(obj, names, i_fix1, "Loslager A: ");
[ntext, nOK]: fb_fix1_name(obj, names, i_fix1);

PRT node 1 test for correct direction

Algebraic test for isOK = true and feedback of {@text@} for both branches.

PRT node 2 test for correct name

Algebraic test for nOK = true and feedback of {@ntext@} in the false branch (with penalty of 0.5).
