Remeshing 3D (FEM / Genormte Berechnungen/ANSYS)

Schau mal in der ANSYS Hilfe nach, bei der Version 10 gehts noch nicht (odder nur mit bestimmten Elementen und Materialien)

6.2. Rezoning Requirements
ANSYS supports manual rezoning for 2-D analyses. Rezoning requires that all multiframe restart files are available. Following are the supported analysis types, elements, materials, loads, boundary conditions, and other rezoning requirements:

Support Category Requirements
Solid elements
PLANE182 -- B-bar method only (KEYOPT(1) = 0).

PLANE183

All stress states (KEYOPT(3)) allowed: plane strain, plane stress, axisymmetric, and generalized plane strain.

Pure displacement formulation (KEYOPT(6) = 0) or mixed u-P formulation (KEYOPT(6) = 1) is allowed.

Contact elements
TARGE169

CONTA171 and CONTA172 with any of the following valid KEYOPT settings:

KEYOPT (1) = 0

KEYOPT (2) = 0, 3, 4

KEYOPT (3) = 0

KEYOPT (4) = 0, 1, 2

KEYOPT (5) = 0, 1

KEYOPT (7) = 0

KEYOPT (8) = 0

KEYOPT (9) = 0

KEYOPT (10) = 0, 1

KEYOPT (11) = 0

KEYOPT (12) = 0, 1, 2, 3, 4, 5, 6

Contact pair behavior
Rigid-flexible -- Target elements and pilot node cannot be remeshed. Maximum of two contact pairs on each solid surface.

Flexible-flexible contact.

Self-contact.

Materials
All hyperelastic materials (TB,HYPER).

Plastic materials defined by TB,BISO, TB,MISO, TB,NLISO, and TB,PLASTIC with TBOPT = MISO.

Analysis types Static analysis with geometric nonlinearity (NLGEOM,ON and SOLCONTROL,ON).

Loads and boundary conditions (BCs)
Displacements, forces, pressures, and nodal temperatures (applied via a BF,TEMP command). No tabular values.

Region to be remeshed The selected nodes inside the region must have the same nodal coordinate system.

Boundary nodes can have different nodal coordinate systems.

Elements must be of the same element type, material, element coordinate system, and real constant.

If two regions with different attributes require remeshing, you must remesh the regions separately. For more information, see Remeshing Multiple Regions at the Same Substep.

Files .rdb, .rst, .rxxx, and .ldhi.

The conditions specified apply only to the region to be remeshed. No limitations exist for other regions, although the analysis type itself must support rezoning.
