Hi, 

Sintering process simulations in Mechanical are performed using the Sintering Process Add-on, which simplifies the setup of the sintering material model. An Additive Suite license is required to use the add-on. 

For more information about sintering process, please refer to the follwing Ansys Help Document:
Sintering Simulation Guide (ansys.com)
