We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

      When a material property is defined with MPDATA command (e.g. MPDATA,EX,MAT,1,c0,c1,c2) each value (c0,c1,c2,c3,c4) corresponds to the property at the MPTEMP temperature (MPTEMP, STLOC, T1, T2, T3). Thus, the property table is associated with the temperature data table. On the other hand when MP command is used (e.g. MP,EX,MAT,c0,c1,c2,c3,c4) a fourth order polynomial as a function of temperature is defined: Property = C0 + C1(T) + C2(T)2 + C3(T)3 + C4(T)4
