115 | <H2>3. Items for migration of the user code</H2> |
---|
116 | |
---|
117 | Listed here is some relevant information on developments included in this |
---|
118 | release, some of which may require migrations (mainly for advanced uses of |
---|
119 | features in Geant4) in order to upgrade from release 8.3 to release 9.0. |
---|
120 | Note that a full re-installation of libraries (or a full recompilation) and |
---|
121 | a recompilation of user applications is anyhow required. |
---|

123 | <P> </P> |

125 | <P> </P> |
---|
126 | The static constants for the geometrical tolerance <TT>kCarTolerance</TT>, |
---|
127 | <TT>kRadTolerance</TT> and <TT>kAngTolerance</TT> which used to be defined |
---|
128 | at global scope, have been now removed.<BR> |
---|
129 | Advanced applications making use of such constants in the code are required |
---|
130 | to retrieve the values for Cartesian, Angular and Radial tolerances through |
---|
131 | the class <TT>G4GeometryTolerance</TT>, a new class providing the methods, |
---|
132 | respectively: <TT>GetSurfaceTolerance()</TT>, <TT>GetRadialTolerance()</TT> |
---|
133 | and <TT>GetAngularTolerance()</TT>. Applications with setups of unusual |
---|
134 | dimensions (e.g. smaller than <TT>1 mm</TT> or larger than <TT>1 km</TT>) |
---|
135 | can now adjust these values, and must do so before creating any part of |
---|
136 | the geometry description. Please see the User's Guide for Application |
---|
137 | Developers for the details. |

140 | <B>Biasing & Scoring</B> |
---|
141 | <P> </P> |
---|
142 | <UL> |
---|
143 | <LI>When defining a parallel geometry for importance biasing, the parallel |
---|
144 | geometry now must inherit from <TT>G4VUserParallelWorld</TT>. This |
---|
145 | has a <TT>GetWorld()</TT> method which creates a (named) copy of the mass |
---|
146 | geometry world volume and later retrieves it.</LI> |
---|
147 | <LI>The different parallel and mass sampler classes have been combined into |
---|
148 | one <TT>G4GeometrySampler</TT> class which requires the following |
---|
149 | instantiation, e.g.: |
---|
150 | <TT>mgs(detector->GetWorldVolume(),"neutron");</TT><BR> |
---|
151 | An additional set method defines whether or not the sampler is in a |
---|
152 | parallel geometry: <TT>mgs.SetParallel(false);</TT> </LI> |
---|
153 | <LI>When a parallel world is created, then parallel navigation must be activated. An application with physics list that uses the <TT>AddTransportation</TT> method will automatically use |
---|
154 | <TT>G4CoupledTransportation</TT> which is picked up by the creation of |
---|
155 | the parallel world copy.</LI> |
---|
156 | <LI>All scoring can be implemented only through the Primitive Scorer |
---|
157 | classes. Users utilising the older scoring classes will need to migrate to using Primitive Scorers. The same functionality is provided apart from G4ScoreTable, but scorers are now attached to logical volumes (in place of geometry cells).. This requires |
---|
158 | explicit copy numbers to be utilised for the same logical volume and the |
---|
159 | <TT>GeometryCell</TT> methods should be accessed through the physical |
---|
160 | volume <B>and</B> replica number method.</LI> |
---|
161 | <LI>A demonstration of the new biasing and scoring is available in |
---|
162 | <TT>examples/extended/biasing/B01</TT> and <TT>B02</TT>.</LI> |

169 | A few methods of the interface classes <TT>G4VEmModel</TT>, |
---|
170 | <TT>G4VEnergyLossProcess</TT>, <TT>G4VEmProcess</TT>, |
---|
171 | <TT>G4VMultipleScattering</TT> were revised, in order to reduce memory |
---|
172 | allocations. All classes inheriting these interfaces were modified accordingly |
---|
173 | (see detailed list of changes). Advanced users with derived classes must make |
---|
174 | similar changes. |

176 | <P> |
---|
177 | Old implementations of physics processes, of configurations frozen in release |

178 | 5.2, have been removed (see below detailed list of changes). |
---|
179 | </P> |
---|
180 | An enumerator of step limitation algorithms of the multiple-scattering process |
---|
181 | has been introduced. It replaces a boolean value . The step limitation types |
---|
182 | are: |
---|
183 | <UL> |
---|
184 | <LI><TT>Minimal</TT> - equivalent to the original algorithm, as implemented in Geant4 7.1 and earlier releases.</LI> |
---|
185 | <LI><TT>UseSafety</TT> - the current default, which makes use of the geometrical safety</LI> |
---|
186 | <LI><TT>UseDistanceToBoundary</TT> - the most advanced, recommended for accuracy in the |
---|
187 | cases where no magnetic field is set.</LI> |
---|
188 | </UL> |
---|
189 | As in releases 8.0 to 8.2, the minimal option (which used to be called |
---|
190 | 'no step limitation') results in fewer steps, and typically provides less |
---|
191 | stability than the other options. |

---|
198 | If desired, user code must switch it on using the method |
---|
199 | <TT>G4HadronicProcess::EnableIsotopeCounting()</TT>. |
---|
200 | Isotope production models allow users to specify their own |
---|
201 | isotope production mechanism and data set, or use G4NDL to get |
---|
202 | the production cross sections. If no model is specified, |
---|
203 | the largest final state nuclear fragment becomes the produced |
---|
204 | isotope. If enabled, isotope production will occur for any |
---|
205 | hadronic model. Only users who have specifically assigned an |
---|
206 | isotope production model in their physics lists will be affected |
---|
207 | by tghe above change.</LI> |
---|
208 | <LI>The old variable <TT>NeutronHPCrossSections</TT> defining the path where |
---|
209 | to load the G4NDL data set has been renamed to <TT>G4NEUTRONHPDATA</TT>, |
---|
210 | so that this variable shares the G4 prefix used for other environment |

218 | |

219 | Removed physics lists <TT>LHEP_HP, QGSP_HP, LHEP_BIC, LHEP_BIC_HP</TT> |
---|
220 | and <TT>LHEP_PRECO</TT>, which were marked obsolete in release 8.2. |
---|
221 | Users are encouraged to evaluate <TT>QGSP_BIC</TT> as a replacement of |
---|
222 | <TT>LHEP_PRECO</TT> and <TT>LHEP_BIC</TT>. The list <TT>LHEP_BIC_HP</TT> |
---|
223 | is replaced by <TT>QGSP_BIC_HP</TT>. In place of the remaining lists |
---|
224 | (<TT>LHEP_HP, QGSP_HP</TT>) we suggest to evaluate <TT>QGSP_BERT_HP</TT> |
---|
225 | and <TT>QGSP_BIC_HP</TT>.<BR> |
---|
226 | Also removed physics lists using the <TT>Mars13</TT> leading particle classes, |

227 | i.e. lists with a name containing <TT>_LEAD_</TT>. |

288 | <LI>When using the high precision neutron module, a user may now choose to |

289 | force the use of the Photon Evaporation model, instead of the neutron |
---|
290 | capture final state data. The environment variable |
---|
291 | <TT>G4NEUTRONHP_USE_ONLY_PHOTONEVAPORATION</TT> must be |
---|
292 | set to do this. For cases in which the final state data does not exist |

293 | in the G4NDL data library, this model was already used and thus there is |
---|
294 | no change. </LI> |
---|
295 | <LI>A user can force high precison neutron code to use only exact isotope |
---|
296 | data files, instead of allowing nearby isotope files to be used. In this |
---|
297 | case if the exact file is not available, the cross section will be set to |

298 | zero and a warning message will be printed. To enable this, set the |
---|
299 | environment variable <TT>G4NEUTRONHP_SKIP_MISSING_ISOTOPES</TT>.</LI> |
---|
300 | <LI>A user can switch off the Doppler broadening due to the thermal motion of |
---|
301 | the target nucleus. The broadening is used to correct the G4NDL data, |
---|
302 | which are at zero temperature. This must be done only for appropriate |
---|
303 | applications. To switch it broadening off, the environment variable |
---|
304 | <TT>G4NEUTRONHP_NEGLECT_DOPPLER</TT> must be set. Then the Doppler |
---|
305 | broadening in the cross section calculation is neglected. However, the |
---|
306 | thermal motion of the nucleus is still taken into account in the Final |
---|
307 | State Generator. This option provides a significant CPU performance |
---|
308 | advantage. It is not suitable, though, for simulation in which low energy (thermal) |
---|
309 | neutrons are important, as related observables are affected.</LI> |

363 | <H2>7. Compilation Warnings</H2> |

364 | |
---|
365 | There are compilation warnings on some tested platforms. We do not believe |
---|
366 | that any of these lead to incorrect run-time behaviour. |

376 | The following message can be written to standard output at the end of a program: |

377 | <PRE> |
---|
378 | G4Transportation: Statistics for looping particles |
---|
379 | Sum of energy of loopers killed: |
---|
380 | Max energy of loopers killed: |
---|
381 | </PRE> |
---|
382 | It provides the total energy (in <TT>MeV</TT>) of tracks killed due to |
---|
383 | excessive number of steps ('looping') during the simulation, and the maximum |
---|
384 | energy of such a track. Such behaviour can be due to looping in magnetic fields |
---|
385 | or encountering problems at geometrical boundaries. |
---|
386 | <P></P> |
---|
387 | In case either of these reported energy is significant, we recommend to |
---|
388 | increase the verbosity of <TT>G4Transportation</TT> to obtain information for |
---|
389 | each track killed. A user can change the threshold energy above which particles |
---|
390 | are not killed using the method <TT>SetThresholdImportantEnergy</TT> of |
---|
391 | <TT>G4Transportation</TT>. The default value is <TT>250 MeV</TT>. |
