Apply Loads
The final step in the model building process is to apply constraints and forces and to create or assign coordinate systems.
Before you apply loads, create a load collector. Loads are displayed in the color assigned to the load collector. The size of loads and constraints is based on model units and can be modified from within the boundary condition panels.
HyperMesh stores and displays all loads in the global coordinate system. Depending on the analysis code being used to calculate results, HyperMesh transforms the loads appropriately to any local nodal output coordinate system.
- Accelerations
- Applies an acceleration at a node. Accelerations are displayed as a single-headed arrow with an optional label, A. The label may also display the magnitude of the acceleration.
- Constraints
- Applies a constraint or enforced displacement at a node. Constraints are displayed as a triangle with an optional label that displays the degrees of freedom affected by the constraint.
- Equations
- Applies a general equation constraint between nodes. Equations are displayed with the label, EQ.
- Fluxes
- Applies a flux load at a node. Fluxes are displayed as a thick arrow with an optional label, flux. The label may include the magnitude of the flux.
- Forces
- Applies a concentrated force along any user-defined vector at a node. Forces are
displayed as a single-headed arrow with an optional label F. The label may include the
magnitude of the force.
Linear interpolation input files for forces require 6 values with a space in between, as follows:
<X location> <Y location> <Z location> <X component> <Y component > <Z component >
- Moments
- Applies a concentrated moment about a user-defined vector at a node. Moments are
displayed as a double-headed arrow with an optional label, M. The label may include
the magnitude of the moment.
Linear interpolation input files for moments require 6 values with a space in between, as follows:
<X location> <Y location> <Z location> <X component> <Y component > <Z component >
- Pressures
- Applies a pressure on an element or geometry. Pressures are displayed as a
single-headed arrow with an optional label, P. The label may include the magnitude of
the pressure.
Linear Interpolation input files for Pressures require 4 values with a space in between, as follows:
<X location> <Y location> <Z location> <magnitude>
- Temperatures
- Applies a temperature constraint at a node. Temperatures are displayed as a straight
line starting at the node at which the temperature is applied extending upward, with
an optional label, T.
Linear Interpolation input files for Temperatures require 4 values with a space in between, as follows:
<X location> <Y location> <Z location> <magnitude>
- Velocities
- Applies a velocity at a node. Velocities are displayed as a single-headed arrow with an optional label, V. The label may include the magnitude of the velocity.
