What is DesignSpace?

• DesignSpace is a simulation tool from ANSYS, Inc.
  that was developed to be used in conjunction with
  3D CAD to provide designers and engineers with
  quick feedback on product design performance
  during the design process.

DesignSpace Technology

• Knowledge-Based Automation is simply taking a
  process, that normally may be complicated or
  require manual intervention, and intelligently
  automating it.
• This is the key to the fast learning curve and
  high degree of success that DesignSpace users
  find.
• Our strategy makes minimal sacrifices in
  flexibility, while gaining tremendous benefits in
  capability, reliability, and speed.

Fatigue Module

• Most parts fail over time due to fatigue. The
  DesignSpace fatigue module allows you extend your
  simulation to address the performance over the
  required product life.
• This module works with the Entra, Advansia, and
  Optima packages. Plus, the license floats
  between multiple copies of DesignSpace.

Fatigue Module

• Fatigue Sensitivity
• Shows how the fatigue results change as a
  function of the loading at the critical location
  on the model.
• Result may be scoped to parts or surfaces.
• Sensitivity may be found for life, damage, or
  factory of safety.
