Codes Description

Notes: For heat transfer, code 9 is used for all heat transfer elements.

When using shells in heat transfer, it is important to enter a code for each layer inchronological order if post file is to be correctly read by the INITIAL STATE orCHANGE

STATE options.


10/16


417

Note that you do not need to select nodal values (that is, displacement, velocities and

accelerations, and temperature for a heat transfer run) as these are automatically written tothe post file.

Eigenmodes (dynamic analysis) and eigenvectors (buckling analysis) are written to

the post file only if indicated by the RECOVER orMODAL

INCREMENT/BUCKLE INCREMENT option.

Layered quantities for beams, shells, composite shells, composite solids, and

rebar quantities.

For many post codes, a layer number is required, and is conventionally one to the last layer

number in the element. Layer 1 is the top layer, layer 2 is the next layer, etc. for shells,

composite shells, bricks, or rebar elements. In many shell applications, the number of

layers in different elements is not the same. Two alternative mechanisms may be used to

specify the layer number:

I.The user can specify the following layer codes:

15000 - top layer

10000 - bottom layer

5000 - middle layer

If the number of layers in a shell is an even number, it will use (nlayer +1)/2 where

nlayer is the number of layers.

II.If the user specifies the layer ID for the composite elements, then the user must specify

the layer ID. This is useful in ply drop-off simulations.

Note that post codes 91-107 refer to failure indices for different failure criteria and postcodes 601-617 refer to associated strength ratios. More than 17 quantities are allowed in

the analysis but only the first 17 quantities are available for postprocessing. For example.

if three failure criteria (say, max. stress, Hoffman and Puck) are flagged, post codes 91-

97/601-607 would contain the six indices/ratios associated with maximum stress, post code

98 / 608 would contain the one index / ratio associated with Hoffman and post codes 99-

103 / 609-613 would contain the five indices / ratios associated with Puck criterion.


11/16


Post codes 691 and 694 provide access to the first and second orientation vectors

respectively. These vectors depict the alignment of the material coordinate system at theelement level with respect to the global cartesian system. They are available for elements

that are either composites, or using materials that are orthotropic/anisotropic / requiring the

HOOKLW ANELAS user subroutines, or using the ORIENTATION option to identify the

material coordinate system. Note that these element orientation vectors are averaged across

all integration points of the element and presented as a single set of vectors at the element

centroid. They are always calculated on the current element geometry and any layer IDs

associated with post codes 691 and 694 are ignored. Note also that while the normal usage

of these post vectors is in conjunction with the ORIENTATION option, if no special material

orientation is provided, then they can also be used to obtain the element coordinate system

for orthotropic materials, composites, etc. For composites, post code 697 provides access

to the fiber angle in any layer. If used without any associated layer id, post code 697

provides access to all layer angles. Else, the user can obtain the angle for a specific layer L

by using 697,L as the post code. Note that if there are no composite elements, post code

697 is ignored. The orientation vectors on the post file are available for visualization in

Marc Mentat. Either element orientations or layer orientations can be plotted. Note that for

layer orientation vectors to be available for a set of layers, the associated layer orientation

angle should be available on the post file through post code 697.

For post codes 411, 421, 431, and 441, global quantities for shell elements are reported for

as many layers as requested and the same layer numbering system is used as for regular

shell quantities. Layer 1 is the top surface; layer 2 is the next surface, etc. This convention

is followed from MSC.Marc 2000 on.

Caution has to be exercised in interpreting the results when strain and/or stress tensors are

requested for beam and shell elements:

1. For most elements in this category (elastic beam elements 31, 52, 98 are exceptions),

stress tensors (post codes 311, 351, 361) or their associated component values (post

codes 11-16, 51-56, 61-66) and total strain tensor (post code 301) or its associated

component values (post codes 1-6) can be requested with or without an associated layer

number. When no layer number is requested, the generalized strains (stretches, shear

strains) are reported for the strain post values and generalized stresses (axial force,

shear forces) are reported for the stress post values. Generalized curvature strains and

generalized moments can be requested through post codes 641 and 651 for shells and

numerically integrated beams. Note that for shell elements, the generalized stresses are

forces per unit length. Refer to Marc Volume B: Element Libraryfor a definition of the

generalized strain and stress output for each element type. When a layer number is

used, the actual strain and stress components at the requested layer are reported. Layer

number are ignored for post codes 641 and 651.


12/16


419

2. For conventional (non-numerically integrated) elastic beams (types 31, 52, 98), there

are no layers - so only the generalized strains and stresses are reported for theseelements. Refer to Marc Volume B: Element Libraryfor a definition of the generalized

strain and stress output for each element type. Equivalent quantities are not computed

for these element types since they do not make physical sense. The thermal strain tensor

(post code 371) or its associated components (post codes 71-76) are available.

3. For other stress tensors (post codes 341, 391, 411) and strain tensors (post codes 321,

331, 371, 381, 401, 421, 431, 441, 461), there are no generalized values and they can

only be requested for a particular layer. If no layer number is provided by the user, by

default, the tensors are reported for layer number 1. Numerically integrated solid-

section beam elements (type 52 or98) have layer numbers and from a postprocessing

perspective behave as open or closed section beams or shells.
