Parameter definition

VariableDescription
units Unit system
options:
SI $\rightarrow$ [m, kg, s]
MMTONS $\rightarrow$ [mm, ton, s]
CMGUS $\rightarrow$ [cm, g, $\mu$s]
IPS $\rightarrow$ [in, slinch, s]
MMKGMS $\rightarrow$ [mm, kg, ms]
CMGS $\rightarrow$ [cm, g, s]
MMGMS $\rightarrow$ [mm, g, ms]

Description

Command to inform the solver of used unit system. A unit system must be specified if the PARTICLE_DOMAIN command is used. Specifying a unit system also facilitates the scanning for suspected errors in the input deck. Possible errors or mistakes are reported in the ASCII file "impetus.attention".

Example

Unit system conversion

Conversion of material parameters from MMTONS to SI units:

*UNIT_SYSTEM
SI
~convert_from_MMTONS
*MAT_METAL
1, 2.7e-9, 70.0e3, 0.3
1
*CURVE
1, 0, 0, strain, stress
0.0, 200.0
1.0, 280.0
~end_convert

The input above is equivalent to:

*UNIT_SYSTEM
SI
*MAT_METAL
1, 2700.0, 70.0e9, 0.3
1
*CURVE
1
0.0, 200.0e6
1.0, 280.0e6
