There are two commands which allow one to examine the forces applied to the system. These forces are computed in the post-processor, so the time step of the computation is that at which the forces are computed.

The options common to both commands are:

-EVENTS, EVE_BEGIN, EVE_END, EVE_INC-MAG_DEFINE, A(1), .. A(n)-FORCE, FORCE_NAME(1), ....., FORCE_NAME(n)

The **-EVENTS** option selects the events which will be considered. Here EVE_BEGIN and EVE_END are the beginning and ending event numbers for which the results will be
computed, and EVE_INC is the increment for computing results. After the results have been computed, MOSES places the user in the Disposition Menu so that he can
dispose of the data. The corresponding form of the **REPORT** command is:

REPORT, REP_NAMES(1), REP_NAME(2), ... -OPTIONS

Here, REP_NAMES(i) is a set of report names which may be selected and will depend on the command issued. The only option available for reporting is again **-EVENTS**. The
**-MAG_DEFINE** option defines how the "Magnitude" is computed. You can have one, two or three A(i) and each on must be either **X**, **Y**, or **Z**. If you specify all three (the
default) then the magnitudes will be the length of the vectors. Alternatively, the magnitude will be the length of the vector projected on to either a line (if one is
specified) or a plane. For example

-MAG_DEFINE X Y

will give you the length of the vector projected onto the X-Y plane. For the **-FORCE** option, FORCE_NAME(i) is a selector which selects forces from the list: **WEIGHT**,
**CONTENTS**, **BUOYANCY**, **WIND**, **V_DRAG**, **R_DRAG**, **WAVE**, **SLAM**, **W_DRIFT**, **CORIOLIS**, **DEFORMATION**, **EXTRA**, **APPLIED**, **INERTIA**, **A_INERTIA**, **C_INERTIA**, **FLEX_CONNECTORS**,
**RIGID_CONNECTORS**, and **TOTAL**. If this option is omitted, only the total force will be computed. The meaning of these forces can be found in the section of FORCES.

The command

ELMFORCE, :ELE_NAME -OPTIONS

is used for elements with two vertices, and the

LDGFORCE, LG_NAME, NODE_NAME(1), .... NODE_NAME(n), -OPTIONS

**LDGFORCE** command is used for generalized plate elements or load groups. For an **ELMFORCE** command, forces will be computed at the two end nodes of all elements which
are selected by the selector :ELE_NAME.

The **LDGFORCE** command operates somewhat differently. Here, one can select only a single group, LG_NAME. The other data on this command is a set of node names,
NODE_NAME(i). If this data is specified, then the forces will be computed at the specified nodes. The computation of force at the specified nodes is accomplished by
first computing a force applied to the element. A least square fit is then performed to reduce this total force and moment to forces at the specified nodes.
