4.6. pressureConstraint command

pressureConstraint(nodeTag, pNodeTag)

Create a pressure constraint for incompressible flow.

nodeTag (int)	tag of node to be constrained
pNodeTag (int)	tag of extra pressure node, which must exist before calling this command

For example,

ops.node(1, 0.0, 0.0)
ops.node(2, 0.0, 0.0, '-ndf', 1)
ops.pressureConstraint(1, 2)
