What's New With Altair Inspire Cast

By Emmy Wolfe on October 24, 2018

A name isn't the only thing that's new in Altair Inspire Cast (formerly Click2Cast). When they changed the name they packed in a lot of updates that will help you make better informed decisions about your cast before it hits the manufacturing stage.

Altair Inspire Cast 

Altair Inspire Cast is a simulation-driven design environment software offering complete casting simulation in five easy steps in a highly intuitive user experience. They focused on making casting simulation as easy as possible by using foundryman's language in the software. This means every word in the interface comes from the casting process world. 

The software is the fastest growing casting simulation in the market and enables users to increase product quality and design better products with a quick ramp-up and only a few hours of training.

New Components 

New Components in Altair Inspire CastAltair Inspire Cast has introduced a new feature for designing or generating additional cast components. This allows you to easily identify or generate components such as core, chiller, riser and much more, as well as select the material used for each of these and can be resized using the geometry tool. 

Cooling Lines

Cooling Lines in Altair Inspire CastThe software now has the ability to support cooling lines. When casting, parts can get hot spots of porosity in inconvenient places, however, cooling lines can help reduce those defects and promote even solidification rates. You can easily create and position cooling lines via the generation tool and creation/manipulation options. With this new functionality, Altair Inspire Cast provides you with the ability to optimize your designs in a way that you never have been able to in the past which will allow you to make informed and upfront decisions to save time and money in the manufacturing process.

Exothermal Support 

Exothermal Support in Altair Inspire CastAt some point in casting solidification with metals, you may need them to stay in a liquid state for a longer period for better feeding efficiency. An exothermal sleeve can help accomplish this. By adding a sleeve to one riser, we are able to compare the results of the solid fraction. The results show that the riser with the exothermal sleeve has low solidification with constant feeding to the casting part and helps us avoid porosity defects. 

Pipe Shrinkage

Pipe Shrinkage in Altair Inspire CastThanks to Altair Inspire Cast, you have the ability to detect casting defects easily. The simulation is divided into two stages, filling and solidification. The result type of temperature, solid fraction and the visualization of shrinkage porosities will allow you to detect both the location and the size of the risers. Macroporosities are shown for an enclosed void of low density due to thermal shrinkage. To detect and dimension isothermal and exothermal sleeves you can use the pipe shrinkage. Microporosities can also be displayed, but their computation is based on Niyama.


Niyama Criteria for MicroporosityWhile a very minuscule defect that occurs in cast parts, microporosity has a devasting consequence on the quality of the project. It's associated with the Niyama criteria which can be defined as the relationship between high cooling rate and temperature gradient and differs from material to material. As you can see in the image, various materials have a different range of values. The lower the Niyama value, the higher the chances are of your part getting microporosity and shrinkage inside the casting.
