Notes

The usrdof command specifies the degrees of freedom for the user-defined element USER300.

Although you can intersperse other commands as necessary for your analysis, issue the usrdof command as part of the following general sequence of commands:

Issue the et command for element USER300, followed by the related The type statement command.

Issue both the usrelem and usrdof commands (in either order).

Define your element using USER300.

The DOF list ( DOF1 through DOF10 ) can consist of up to 10 DOFs. Use any valid and appropriate DOF (such as UX, UY, UZ, ROTX, ROTY, ROTZ, AX, AY, AZ, VX, VY, VZ, PRES, WARP, TEMP, VOLT, MAG, EMF, and CURR).

You can specify a maximum of 10 DOFs per usrdof command. To define additional DOFs, issue the command again.

The maximum number of DOFs for a user-defined element–the number of nodes times the number of DOFs per node–cannot exceed 480.
