| | How it works in 2 examples: |
| | - ''macro/fwall/fair/create_fwallgeo_testModules.C'' -> meant only for visual inspection of the definition of individual modules!! Each module size is defined with its dimensions plus the needed definition of dimensions for the channel for WLS fibre (curvature at corners, distance from the edge, width and depth). The macro reads the material properties from ''media.geo'' file and constructs geoVolumes for each size of the module, e.g. ''TGeoVolume* smallModule = ConstructSmallModule( "smallModule", smallCellSize, wallThickness, &infoFile)''. Then these virtual volumes are placed into the mother volume with a specific module index (this is important as each volume has to have unique name!!) and the position of the centre, using: ''fwall->AddNode(smallModule, iModule, new TGeoTranslation(xCurrentModuleCentre,yCurrentModuleCentre,0))''. The modules are placed one next to each other. After that the constructed fwall is positioned into the cave: ''top->AddNode(fwall, 0, fwallTrans)''. The modules are built via common function ''ConstructGeneralModule(many parameters)'' in which the modules are constructed with basic geometrical volumes and transformations. |
| | - ''macro/fwall/fair/create_fwallgeo_firstShot.C'' -> the only difference is in the positioning of modules into ''TGeoVolume fwall''. Done in a way that there are 4 inner modules missing (beam) and then going outwards small modules in array 6x4, medium modules 3 in x direction and 2 in y, large modules 2 in both x and y directions. If one want to change the layout then change the variables: ''nSmallCells_X, nSmallCells_Y, nMediumCells_X, nMediumCells_Y, nLargeCells_X, nLargeCells_Y''. To change the dimensions of modules: ''wallThickness, small/medium/largeCellSize''. |

| | Running simulation with a defined setup (consisting the FWALL) |
| | |
| | If you have developed new FWALL geometry |
| | - within X2Go: |
| | - make sure you will have OpenGL library (''export LIBGL_ALWAYS_INDIRECT=1'') |
| | - load proper version of CBM-ROOT (''source /u/USERNAME/fwall/cbmroot/build_LINUXVERSION/consig.sh --prepend'') |
| | - go to the macro which will create the geometry and run the macro ('' root -l 'create_fwallgeo_firstShot.C("v22a")' '') |
| | - move created files into the intended directory (''mv fwall_v22a.* /u/USERNAME/fwall/cbmroot_geometry/fwall/'') |
| | - define new or modify CBM setup to include your new geometry (e.g. within ''setup/setup_sis100_hadron_fwall.C'' the correct tag must be specified ''TString fwallGeoTag = "v22a"'') |
| | - these changes should be propagated into GitLab (git add, git commit, git push) |
| | - finally the ''/u/USERNAME/fwall/cbmroot/external/InstallGeometry.cmake'' must be updated to the proper commit hash with these changes |
| | - re-install the CBM-ROOT |
| | |
| | Make use of the geometry within |
| | - logged-in to virgo-debian10.hpc.gsi.de |
| | - using the ''cbmroot/macro/run/run_tra_file.C'' with **setup_sis100_hadron_fwall** in the default parameter |
| | - execute either manually ''root -l -b -q run_tra_file.C'' or with sendJobArrayScript.sh as described in repository XXXX |
