Review the following known issues and limitations:
Use Metric units for sintering analyses to avoid issues associated with Imperial units in Ansys releases 2022 R2 through 2025 R2.
Upon initiating a solve, the Sinter Material object generates an APDL script corresponding to the APDL sinter material. The Sinter Material object is a standalone implementation that is currently not integrated into Engineering Data.
Certain features of the APDL nonlinear material are accessible only with APDL scripting. For such features, Ansys recommends you specify the material assignment via APDL commands (TB, SINT).
Anisotropic shrinkage (TB, SINT,,,,ANICONST)
Time step control based on maximum viscous strain increment (CUTCONTROL, VSLIMIT)
Newer users who are less familiar with APDL scripting for material assignments can use the wizard to generate the ds.dat input file and use it as a reference.
