Introduction
The Modif file allows the following options to be added during a run:
| • | Groups, lines or surfaces |
| • | TH output (except Subsets and Parts) |
| • | Restart SPMD simulation with different number of processors |
Modif files have the name: Runname_run#.rad
where, run# is the RADIOSS run number four digits from 0000 to 9999 and run# is the name of the last Restart file + 1.
For example, to run a Modif file after the first run, restart file Runname_0001_cpu.rst
where, cpu # is the number of processors (four digits), and cpu # = 0000 = SMP RADIOSS version.
The run number for the Modif file must be Runname_0002.rad.
The figure below illustrates the use of a Modif file: Name of the input file and the name of the program to be used.
Modif files use the same input format as RADIOSS V10 Block input format; with the exception of a limited choice of options are available.
Except for the header formats, blocks may be input in any order.
The Modif files option is not compatible if using Madymo-RADIOSS Coupling.
Run Description Header Format
This line must be the first in RADIOSS deck.
#RADIOSS Starter
The following keywords are available.
All types of elements or node groups:
All options: To find the exact format, refer to the relevant section of this manual.
| Note: | Use Istf=0 in INTER/TYPE7 and TYPE11. Istf=2, 3, 4, and 5 are not available in these two interfaces. |

Limitation of MODIF files
The following RADIOSS options are not available for the use of MODIF files:
| • | Failure model (/FAIL/TAB1) |
| • | Failure model (/FAIL/CONNECT) |
| • | Madymo (/MADYMO/EXFEM and /MADYMO/LINK) |
| • | All Lagrange multipliers (example: /GJOINT is not available) |
| • | /IMPDISP, /IMPVEL, /IMPACC |
| • | Interface type 2 with “Spotflag=25” (/INTER/TYPE2) |
| • | Interface type 7 and ISTF > 1 (/INTER/TYPE7) |
| • | Interface type 11 and ISTF > 1 (/INTER/TYPE11) |
| • | Interface type 14 (/INTER/TYPE14) |
| • | Interface type 16 (/INTER/TYPE16) |
| • | Interface type 17 (/INTER/TYPE17) |
| • | Interface type 20 (/INTER/TYPE20) |
| • | Interface type 21 (/INTER/TYPE21) |
| • | Interface type 23 (/INTER/TYPE23) |
| • | Interface type 24 (/INTER/TYPE24) |
| • | Solid property type 29 or 30 or 31 (/PROP/TYPE29, /PROP/TYPE30 or /PROP/TYPE31) |
| • | Material law 59 (/MAT/LAW59) |
| • | Material law 77 (/MAT/LAW77) |
Comments
| 2. | After the header format, you may insert comment lines. These lines must begin with $ or #. |
| 3. | If you need to have a Runname (run identification name), this input is introduced by the keyword /BEGIN. |
