mpoint fix command

Syntax

mpoint fix keyword ... <range>

Primary keywords:

pore-pressure    velocity    velocity-x    velocity-y    velocity-z

Set the mpoint velocity or pore pressure, if specified, and fix the quantity. This is accomplished for velocities by applying a penalty force to the mpoints. Fixing the mpoint node velocity (mpoint node fix) is preferable.

pore-pressure <f >

The pore pressure is fixed.

velocity <v >

The translational velocity is fixed.

velocity-x <f >

Fix the \(x\)-component of the translational velocity.

velocity-y <f >

Fix the \(y\)-component of the translational velocity.

velocity-z <f > (3D ONLY)

Fix the \(z\)-component of the translational velocity.
