      Speed up gap crossing check in OPAL-CYCL with trivial changes: · bd41d12d
      Matthias Toggweiler authored
          - Inlined ParallelCyclotronTracker::checkGapCross into ::push
          - Convert perpendistance from mm to m, do calculations in m
          - Only compute distOld when necessary, stop if is already clear that
            no cross occurs
          - Integration timer for firstTurn.in example is more than 15 % smaller
            (LF and MTS profit from that, not yet RK4 because RK4 uses old function)

      In OPAL several different TRACK's can performed within one simulation (does not hold for OPAL-cycl yet) this together with 
      the restart capabilities calls for a delicate logic.
      Different tracks, looks like: 
      TRACK, LINE= Injector, BEAM=beam1, MAXSTEPS=100, DT=1.0e-12, ZSTOP=0.14;  
      TRACK,LINE= Injector, BEAM=beam1, MAXSTEPS=50, DT=1.0e-11, ZSTOP=0.20;
      A run with the arguments -restart -1 will continue a track from the last dump in the h5 file. Other the from the last track will
      at the moment certainly fail in the general case. 
      - The h5 attribute TrackStep is not longer available anymore. Two new attributes: LocalTrackStep and GlobalTrackStep are introduced instead.
      - LocalTrackStep refers to the track step in a track command (0 ... 99 and 0... 49 in teh above example), where the GlobalTrackStep is the 
      accumulated number of steps i.e. 0 ... 149, shown in OPAL's screen output. Both local and global track steps are also written into the h5 file 
      in order to properly restart the simulation.
      - The PartBunch object has get/set and increment functions:
          inline void setGlobalTrackStep(long long n) {globalTrackStep_m = n;}
          inline long long getGlobalTrackStep() const {return globalTrackStep_m;}
          inline void setLocalTrackStep(long long n) {localTrackStep_m = n;}
          inline long long getLocalTrackStep() const {return localTrackStep_m;}
          inline void incLocalTrackStep() {localTrackStep_m++; globalTrackStep_m++;)
      - In OPAL-cyc getTrackStep is replace by getLocalTrackStep assuming we only have one TRACK in the simulation.
      - In the ParallelTTracker at the end of the main loop (in execute()) obsolet code is removed (cleanup monitors etc.)
      For details see the diff :-)
      Still some work todo: 
      a) Need to remove: setLastStep in ParallelTTracker.cpp and in general
          getInstance()->getRestartStep() maybe not!
      b) The get/set and increment functions could very well be in an other class!
      c) ParallelPlate tests are broken but maybe also because of other changes need to fix this 
         together with Chuang and Achim
      d) Make sure the restart works in OPAL-cycl we do not have yet a regression test for that.

      Cleanup for CYCL · 7af55a0b
      Matthias Toggweiler authored
          - simplify checkNumPart
          - clean up function initDistInGlobalFrame
                - correct indentation
                - move AUTO mode stuff down where meanR is calculated already
          - referenceR is not used in Tracker_MTS body, so remove it

      Changed MTS variant for OPAL-CYCL · 7f504ec2
      Matthias Toggweiler authored
          - Different splitting allows any positive integer for MTSSUBSTEPS option
          - Requires still one space charge solve per step, but one additional
            solve before main loop. Therefore, extract code to function
          - TODO: correct location of bunch injection code?

      Multiple time stepping (MTS) integrator for CYCLOTRON-T · 6f40a6de
      Matthias Toggweiler authored
          - Additional method ParallelCyclotronTracker::Tracker_MTS
          - If successfully tested, it should replace Tracker_LF
          - Detailed description and sample input file will follow
          - Brief usage guide:
              - Use 'TIMEINTEGRATOR="MTS"' instead of 'TIMEINTEGRATOR="LF-2"'
              - The outer, large step is for integration of space charge, the substeps
                for everything else.
              - Define number of substeps per step with 'Option, MTSSUBSTEPS=10;'.
                This must be an even number >= 2.
              - The input file has to be rewritten in units of the large step, so
                divide STEPSPERTURN, PSDUMPFREQ (and others) by MTSSUBSTEPS to
                maintain similar behaviour.
              - MTSSUBSTEPS and SCSOLVEFREQ both describe the frequency of space
                charge solves compared to the basic step. However, MTSSUBSTEPS
                can be chosen larger while maintaining accuracy. Try it :-)
