ansys.mapdl.core.Mapdl.fj

Mapdl.fj(elem='', label='', value='', **kwargs)

Specify forces or moments on the components of the relative motion of a joint element.

Mechanical APDL Command: FJ

Parameters:

elemstr

Element number or ALL to specify all joint elements.

labelstr

Valid labels:

• FX - Force in local x direction.

• FY - Force in local y direction.

• FZ - Force in local z direction.

• MX - Moment about local x axis.

• MY - Moment about local y axis.

• MZ - Moment about local z axis.

valuestr

Value of the label.

Notes

Valid for MPC184 (joint options in KEYOPT(1)).

In a mode-superposition harmonic or transient analysis, you must apply the load in the modal portion of the analysis. Mechanical APDL calculates a load vector and writes it to the MODE file, which you can apply via the lvscale command.

See fjdele for information on deleting forces and moments.
