While fiber-reinforced composite materials add strength to a component while reducing its weight, problems with differential cooling of the fiber and matrix can lead to residual stresses and strains, resulting in deformation. Ansys Composite Cure Simulation (ACCS) software combines the thermal and structural simulation capabilities of Ansys Mechanical with a chemical solver to solve curing problems throughout the process. The chemical solver’s embedded transient thermal system simulates the development of polymerization, the transition temperature, and internal heat generated by exothermal crosslinking reactions to ensure that the final component has the desired size and shape with no deformation.
Emerging threats worldwide require rapid response in the form of new defense technologies. Engineers are using Ansys multiphysics simulations to reduce development costs for advanced avionics, hypersonic, stealth aircraft and autonomous aircraft.

Ansys EnSight animation of the internal flow and combustion of an internal combustion engine. EnSight’s keyframe animation was used to introduce the parts of the model and uses particle traces to show the complex transient fluid flow. EnSight’s data fusion capability shines by displaying a plot side by side with the 3-D model. This was all done in EnSight, not in a separate video editing application.
