Batch Mode command line descriptions of all the options

modelbuilder [-h] [-p <str>] [-li <str>] [-ro <str>] [-cm] [-rom <str>] [-noe <num>] [-bre] [-brm] [-brf] [-brc]
  -h,   --help                  # displays help on the command line parameters
  -p,   --project=<str>         # path to iROM-project file
  -li,  --loadsinput=<str>      # path to the loads (input) file
  -ro,  --resultsoutput=<str>   # path to the result (output) file
  -cm,  --compilemodel          # compile 3D model
  -rom, --rommethod=<str>       # select the rom method, value can be either "fem" or "qa"
  -noe, --eigenvalues=<num>     # number of eigenvalues
  -bre, --builromeigen          # build rom model [eigensolution]
  -brm, --builrommech           # build rom model [addtional mechanics]
  -brf, --builromfluid          # build rom model [fluidmechanics]
  -brc, --builromcomb           # build rom model [capacitances/ pcaps/ damping combcells]

Full Example:⚓︎

C:\Users\USERNAME\AppData\Roaming\i-ROM\modelbuilder.exe -p D:\Simulation\MYPROJECTPATH\PROJECTNAME.iromproj -li Load_example.irommod -ro Result_Example.txt -cm -rom FEM -noe 10 -bre -brm -brf -brc

This example first triggers "Build Solids", then "Build ROM" and finally executes a simulation.

Build Solids and Build ROM Only (Prepare Model)⚓︎

C:\Users\USERNAME\AppData\Roaming\i-ROM\modelbuilder.exe -p D:\Simulation\MYPROJECTPATH\PROJECTNAME.iromproj -cm -rom FEM -noe 10 -bre -brm -brc
  • It is the recommended workflow to "Build Solids" and "Build ROM" first, then in a second step trigger a simulation based on a prebuild model.

Run Simulation Using Prebuilt Model⚓︎

C:\Users\USERNAME\AppData\Roaming\i-ROM\modelbuilder.exe -p D:\Simulation\MYPROJECTPATH\PROJECTNAME.iromproj -li Load_example.irommod
  • This step is recommended when a valid ROM build already exists.
  • It’s typically used for iterating through different load cases (e.g. varying a voltage).
  • An optimal workflow is to run one simulation, evaluate the result, save it and then define a new parameter set.

Additional Batch Mode Specific Commands⚓︎

These Commands are only valid within the load case script and are i-ROM specific commands to extract rom or simulation results. Examples can be found in the following explorer folder "%appdata%\i-ROM\ProjectFiles\BatchMode"

Export ROM Model Data Values⚓︎

Export all ROM processor data

RDAT;

Export ROM processor nodal results

RNOD,nodeType,nodeNumber,direction;
  • param1: node type [rb, mn]
  • param2: node number [int]
  • param3: result type [fx, fy, fz- force], [mx, my, mz - moment], [ux, uy, uz - displacement], [rx, ry, rz - rotation]

Export ROM Frequencies

RFRQ,startInded,endIndex,indexStep;

Example:´

RFRQ;
RFRQ,all;
RFRQ,index;
RFRQ,startInded,endIndex,indexStep;

Export rom damping matrix 

RDMA;

Example:

RDMA;
RDMA,mat;
RDMA,prop;

Export Solution Values⚓︎

Export all solver/solution data

SDAT;

Export solver/solution operation point.

SOPP,rb,bodyNumber,direction,flag;

(Similar to the SCON and SNOD command.)

Export solver modal amplitude (q-Values)

SMAQ,mode_nr,flag;

Example:

SMAQ,mode_number;
SMAQ,mode_number,compl;
SMAQ,mode_number,ampl;
SMAQ,mode_number,phase;

Export Solver Frequencies (simulation type harm)

SFRQ,startInded,endIndex,indexStep;

Example:

SFRQ;
SFRQ,all;
SFRQ,index;
SFRQ,startInded,endIndex,indexStep;

Export solver derivative of q with respect to time (dq/dt) (simulation type harm)

SQDT;

Export command solver time (simulation type trans)

STIM,startInded,endIndex,indexStep;

Example:

STIM;
STIM,all;
STIM,index;
STIM,startInded,endIndex,indexStep;

Export solver omega (simulation type moda)

SOMG;

Export solver scale (simulation type moda)

SCAL;

Export solver sweep label (simulation type stat)

SWPL;

Export solver sweep value (simulation type stat)

SWPV;

Interface Export Commands⚓︎

For the interface export commands, the subsequent FileName parameter is optional. Additional settings can be configured in the i-ROM project file (*.iromproj) or the i-ROM model file (*.irommod, *.iromsket).

First, execute “Build Solids” and “Build ROM”. Then, the interface export commands can be added to the load case file (loads_*.irommod).
