Appendix 5: Data file for remeshing
Note: By default, one can realize a remeshing with an empty .REM file, i.e. containing 8 blank lines. In this case, the default options are taken into account.
| 1st line (12I5) | |
|---|---|
| LCASE5 | Choice of the transfer method for σ and κ for the internal elements |
| = 0 → interpolation between the new IP and the old IP by the1/RN method (default option) | |
| = 1 → interpolation between the new IP and the old IP by the generalized finite differences method | |
| = 2 → 2-step method a) in the old mesh, extrapolation of the IP at the nodes by modified interpolation functions and then average at the nodes which belong to the same material; b) interpolation at the IP of the new mesh by the classical interpolation functions of the element. |
|
| NSTAR10 | If LCASE = 0 → exponent N of the 1/RN interpolation (N=2 by default) |
| If LCASE = 1 → number of points included in the radius of the central point to be interpolated = 16 or 20 = 100 if one wants all the nodes of the mesh |
|
| If LCASE = 2 → no effect | |
| METH15 | If LCASE = 0 or 2 → no effect |
| If LCASE = 1 → choice of the method to select the points of the patch = 1 inscribed in a square = 0 inscribe in a circle |
|
| IANGLI20 | Parameter for the automatic computation of the lines (solid angles of intersections) in case of parabolic elements |
| = 0 (default value) | |
| = 1 allows not to consider as line the elements sides topologically parabolic (see parameter ANGPRE for the definition of a topologically parabolic side) | |
| NPT25 | Number of points for the smoothing of P and τ of the contact = 1 by default |
| IEMUL30 | Signification of the real parameter EMULT (cf. line 4) |
| = 0 → EMULT is the multiplyer of the number of elements of the father mesh (default value) | |
| = 1 → EMULT is the absolute number of elements of the son mesh | |
| IADP35 | Plastic admissibility for the elastoplastic law 72 (PLASOL) |
| = 0 → nil (default value) | |
| = 1 → the stress states transgressing the plastic criterion are corrected by a return on the plasticity surface (recommended if LCASE=2 and/or if hardening). This return is made along the normal to the modified plastic surface (dilatancy equal to zero). In case of hardening, the hardening variable (equivalent plastic strain) is computed by the transfer of remeshing algorithm, and the derived variables are actualized from the hardening rule. | |
| MODETQ40 | Regrouping method for the triangles used by GMAILL (see manual) |
| = 0 → default value | |
| = 1 → other method | |
| ITYPC45 | Type of meshing created by GMAILL (see manual) |
| = 1 → frontal meshing (default value) | |
| = 2 → structured meshing | |
| IMARK50 | Actualization of the passive markers stocked on the file *.MKP |
| = 0 → nil (default value) | |
| = 1 → actualization of the markers | |
| ICONIN55 | Particular treatment of the new interfaces |
| = 0 → nil (default value) | |
| = 1 → the εeq are put to zero for the new CNTCP groups (useful if interfaces for which the elastoplastic law PLASOL is used with hardening are added). | |
| INDMOD60 | Number of nodes whose coordinates have to be modified according to the user's choice |
| = 0 → nil (default value) | |
| > 0 → Number of nodes whose coordinates have to be modified (to be defined later in the file) | |
| 2nd line (7I5, 2G10.0) | |
