Comments
- Fields 3, 4, and so on of this entry correspond, field-by-field, to fields 3, 4, and so on of the MAT2 entry referenced in field 2. The value in a particular field of the MAT2 entry is replaced or modified by the table referenced in the corresponding field of this entry. In the example shown, G11 is modified by TABLEDi 32; G33 is modified by TABLEDi 15; RHO is modified by TABLEDi 44 and GE is modified by TABLEDi 62. Blank or zero entries mean that there is no frequency dependence of the field on the MAT2 entry.
- The MATF2 entries may refer to blank entries on the respective MAT2 card. In this case, they will be applied to default values of respective parameters.
- In Modal Frequency Response Analysis, the frequency-dependency is only used in the frequency response part of the solution, not in the modal analysis part of the solution.
- This card is represented as a material in HyperMesh.
