# Pressure (hwx.inspire.core)¶

A pressure is a distributed force that acts perpendicular to every point along the face.

Pressures typically arise from gases or liquids pressing on a face and can act in either the inward or outward direction on a solid. To apply a distributed force to a face that acts in a single uniform direction across the entire face, use a force instead of a pressure.

## Attribute Details¶

### active : Bool¶

Returns or sets the object activeness.

Setting this on or off sets all children. Setting to True sets all the parents active too.

### color : Color¶

The color assigned to the Boundary Condition.

The search radius for the Boundary Condition.

### connectionType : Enum (rigid, flexible)¶

The type of the connection. Valid choices are:

• rigid
• flexible

### direction : Direction¶

Returns the direction vector of the entity.

### distributed : Bool¶

Returns whether the applied boundary condition is distributed or not.

Boundary conditions applied across the entire feature area (for faces) or length (for edges) are distributed and at a single point boundary conditions are non-distributed.

### features : Attribute¶

Returns a list of features the entity is applied to.

### inward : Bool¶

Returns True if pressure acts in the inward direction on the solid, False if it acts in outward direction.

### localToPart : Bool¶

Returns or sets ‘Rotate with part’.

It makes boundary condition not to rotate or rotate along with its associated part.

### location : Location (units=”length”)¶

Returns the location of the entity.

### magnitude : Double (units=”pressure”)¶

The magnitude of the pressure, specified in terms of force per unit area.

### mode : Enum (direction, components)¶

Specifies the mode of the boundary condition.

Valid choices are:

• direction
• components

### name : Attribute¶

Returns or sets the name of the object.

It can be any text string, including spaces, although it’s best to avoid using the following characters: ” ‘ * ? and \$.

While these characters are allowed, they could create difficulties when you export the model to other applications.

### part : Attribute¶

Returns the part on which the entity is applied graphically.

### parts : Attribute¶

Returns a list of parts on which the entity is applied on.

### type : Enum (Uniform, Interpolated)¶

The type of the pressure.

You can apply a non-uniform distributed pressure (Interpolated) using the interpolationData property.

### visible : Bool¶

Determines whether the Boundary Condition is visible or not.

## Property Details¶

interpolationData()

A list of named tuples containing the position (Point(x, y, z)) and the magnitude of the pressure in it, used to apply a non-uniform distributed pressure. To set you can pass nested iterables where the inner flattened has four elements. For example, valid inputs are [(math.Point(0, 0, 0), 100)] or [((0, 0, 0), 100)] or [(0, 0, 0, 100)].
