u3.03.01 Mesh file interface IDEAS with Aster

Summary:

The purpose of this document is to describe the principle of the IDEAS (SDRC) interface with*Aster*.

This interface is activated in*Aster* by the procedure PRE_IDEAS [U7.01.01].

The datasets in the universal file I- DEASTM re-read by the IDEAS - Aster interface are dataset 151 (title), datasets 15, 781 or 2411 (node coordinates), datasets 71, 780 or 2412 (description of the meshes), datasets 752, 2417 - Aster, read again by the - Aster interface, are dataset 151 (title title), datasets 15, 781 or 2411 (node or mesh groups), datasets 71, 780 or 2412 (mesh description), datasets 752, 2417, 2417, 2429, 2429, 2430, 2430, 2431, 2432, 2435 or 2467 (cluster of nodes or meshes), and the dataset 735 (knots or meshes attached to curves, meshs area and meshs volume).

Therefore, the versions I- DEASTM currently supported are versions 4, 5 and 6 as well as versions 1., 2., 3., 4., 5., 6., 7., 7., 7., 8., 8., 8., 8., 8., 9. and 10. of Master Series.
