/ANIM/NODA - Animation Files containing Nodal Scalar Data

Description

Generates animation files containing nodal scalar data.

Format

/ANIM/NODA/Restype

Data

Description

Restype

Nodal data type:

DT - Nodal time step

DMAS - Mass variation (see time step control /DT/NODA/CST)
(Comment 1)

DINER - Output of added inertia per nodes (Comment 2)

NDMAS - Non-diagonal mass variation (see time step control /DT/AMS)
(Comment 3)

DAMA2 - Damage for TYPE2 interface (Comment 4)

DENS - Nodal density (Comment 6)

P - Nodal pressure (Comment 6)

TEMP - Nodal temperature (Comments 5 and 6)

Comments

1.anim_noda with DM = M - M0.
M0 is the nodal mass at the beginning of the restart
M is the current mass
2.DM is re-set to 0 at the beginning of each restart file.

anim_noda_diner

I0 is the nodal inertia at the beginning of the current run
Inertia(t) is the current inertia
3.In case /DT/AMS is used, a non-diagonal mass matrix is used, which allows to increase the time step on each line of the mass matrix, the lumped mass M0 is increased with some value symbol_triM which is compensated with non-diagonal terms, in order for the total mass to remain constant. Then:

anim_noda_ndmas

4.DAMA2 damage percentages for interface TYPE2 with rupture (Spotflag = 20, 21, or 22):

anim_noda_norm_displace

anim_noda_tangent_displacement

5./ANIM/NODA/TEMP is used generally to output nodal temperature for finite element formulation of thermal exchange.
6.These options are also available for 3D ALE and FVM airbag problems. The material density, pressure, and temperature is extrapolated to the element nodes, in this case. For FVM airbags the values are extrapolated only to nodes of external and internal airbag surfaces.
