# Mat Sim
The Mat Simulator utility is a powerful utility used to predict the hardness, volume phase fractions, and strain for a defined thermal process for a single point rather than a 2D or 3D geometry. The heating/quenching schedules can be applied as time-temperature tabular data, or rate-temperature-time tabular data.
## Use Case
The Mat Simulator utility is an FEA tool used to predict the strain, volume fraction, etc. for a specific point, based off of a thermal history.
For this example, we are going to use the 1020 material found inside the DANTE material database.
As for the heating and cooling schedule, we defined a rate of 5 oC/s to a target temperature of 950 oC and a cooling rate of -20 oC/s to a target temperature of 20 oC.
One input that can be adjusted depending on the material is the initial phase composition. For this analysis, the initial phase composition is 50% ferrite 50% pearlite. If the initial phase composition was 100% martensite, the strain will be affected, which will affect the final stress and distortion of the part.
Similar to some of the other utilities, Mat Simulator can also be used to adjust the phase transformation kinetics to personalize some of the default materials within the DANTE material database.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://dante-solutions-inc.gitbook.io/dante-6.3-help-documentation/introduction-2/mat-simulator.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
