159 | <H2>6. Items for migration of the user code</H2> |
---|
160 | |
---|
161 | Some migrations may be necessary for advanced uses of features in Geant4 |
---|
162 | in order to upgrade from release 7.1 to release 8.0. Note that a full reinstallation |
---|
163 | of libraries (or a full recompilation) and a recompilation of user applications |
---|
164 | is required. |
---|
165 | |
---|
166 | <P> </P> |
---|
167 | <B>Creating and instantiating physics lists : impact of the revised, "non-static", particle |
---|
168 | definitions</B> |
---|
169 | <P> </P> |
---|
170 | In this release, all particle-definition objects are instantiated dynamically |
---|
171 | when the method <TT>ConstructParticle()</TT> of the user's <TT>G4VUserPhysicsList</TT> is |
---|
172 | called. |
---|
173 | This method is invoked when the user's physics list is assigned to the |
---|
174 | <TT>G4RunManager</TT> (whereas previously it was called at the |
---|
175 | time of |
---|
176 | <TT>G4RunManager::Initialize()</TT>). The new scheme allows the |
---|
177 | user to set a number physics quantities to alternative values (e.g. masses of |
---|
178 | elementary particles) before particles are instantiated with the values provided by Geant4. |
---|
179 | This new scheme creates some restrictions which can |
---|
180 | affect on the existing users's codes, in particular when user-defined |
---|
181 | physics lists are used: |
---|
182 | <OL> |
---|
183 | <LI>Physics processes and models must be instantiated in the |
---|
184 | <TT>ConstructProcess()</TT> method of the user's physics list.<BR> |
---|
185 | In particular physics processes or models <em>must not</em> be data members of a physics |
---|
186 | list. The reason is that some existing physics processes and models require |
---|
187 | that particles have been instantiated already. If a process is a data member |
---|
188 | of the physics list, it is instantiated when the physics list's constructor |
---|
189 | is called, and thus before the invocation of <TT>ConstructParticle()</TT>.<BR> |
---|
190 | The "educated-guess" physics lists distributed with previous Geant4 releases |
---|
191 | are affected by this change. The revised physics lists, which are distributed |
---|
192 | with this release, should be used in their place. |
---|
193 | A user adopting his/her own physics list, will need to perform a similar |
---|
194 | revision in case a <TT>G4Exception</tt> with the following message occurs |
---|
195 | when the physics list is instantiated:<BR> |
---|
196 | <em>Error message</em>: |
---|
197 | <PRE> |
---|
198 | Access to G4ParticleTable for finding a particle or equivalent operation |
---|
199 | occurs before G4VUserPhysicsList is instantiated and assigned to |
---|
200 | G4RunManager. Such access is prohibited by Geant4 version 8.0. |
---|
201 | To fix this problem, please make sure that your main() instantiates |
---|
202 | G4VUserPhysicsList and set it to G4RunManager before instantiating |
---|
203 | other user classes such as G4VUserPrimaryParticleGeneratorAction. |
---|
204 | </PRE> |
---|
205 | <em>Fix:</em> |
---|
206 | All physics processes and models defined as data members of the physics |
---|
207 | list must be moved to the <TT>ConstructProcess()</TT> method, and must be |
---|
208 | explicitly instantiated by <TT>new</TT> operator. The revised physics lists |
---|
209 | provide a reference for this revision.</LI> |
---|
210 | <LI>User action classes (derived from <TT>G4VUserPrimaryGeneratorAction, |
---|
211 | G4UserRunAction, G4UserEventAction, G4UserStackingAction, |
---|
212 | G4UserTrackingAction</TT> and <TT>G4UserSteppingAction</TT>) must be |
---|
213 | instantiated after the physics list is instantiated and after it is set to |
---|
214 | <TT>G4RunManager</TT>. Please note that the user's detector construction |
---|
215 | class is a user initialization class and thus is not affected by this |
---|
216 | restriction.<BR> |
---|
217 | The user should revise the <TT>main()</TT> function if the following |
---|
218 | <TT>G4Exception</TT> occurs:<BR> |

219 | <em>Error message</em> (for <TT>G4VUserPrimaryGeneratorAction</TT>): |
---|
220 | <PRE> |
---|
221 | You are instantiating G4VUserPrimaryGeneratorAction BEFORE your |
---|
222 | G4VUserPhysicsList is instantiated and assigned to G4RunManager. |
---|
223 | Such an instantiation is prohibited by Geant4 version 8.0. To fix this |
---|
224 | problem, please make sure that your main() instantiates G4VUserPhysicsList |
---|
225 | AND set it to G4RunManager before instantiating other user action classes |
---|
226 | such as G4VUserPrimaryParticleGeneratorAction. |
---|
227 | </PRE> |
---|
228 | <em>Fix:</em> |
---|
229 | Edit <TT>main()</TT> to make sure all user action classes are |

230 | instantiated after the physics list is set to <TT>G4RunManager</TT>.</LI> |

236 | A signature change is implemented in the <TT>G4VProcess</TT> base class.<BR> |
---|
237 | The virtual method <TT>StartTracking()</TT> defined in <TT>G4VProcess</TT> |
---|
238 | now takes <TT>const G4Track*</TT> as argument in its signature. Users |
---|
239 | implementing their own physics process and making use of this virtual |
---|
240 | method, will have to modify the signature accordingly. |
---|
241 | |
---|
242 | <P> </P> |
---|
243 | <B>Multiple Scattering electromagnetic process</B> |
---|
244 | <P> </P> |
---|
245 | In the electromagnetic standard package major changes have been introduced |
---|
246 | concerning the Multiple Scattering process. To improve the behaviour of low |
---|
247 | energy particles (electrons in particular, but affecting also hadrons), |
---|
248 | the Multiple Scattering now limits the step size for the particles. This |
---|
249 | restriction is undertaken using several criteria, and is applied systematically, |
---|
250 | in all volumes and materials. In addition a model of the correlation between |
---|
251 | lateral displacement and final direction has been implemented (see the |
---|
252 | Physics Reference Manual for further information).<BR> |
---|
253 | As a result, most physical observables become more stable when varying |
---|
254 | production cuts (i.e. less "cut dependent"). There is a corresponding |
---|
255 | cost, a CPU-time penalty, when utilising the same value of the production |
---|
256 | thresholds. This penalty can be significant, depending on the user's setup and |
---|
257 | the cut values. For many use cases the increased stability will allow the choice |
---|
258 | of higher production thresholds, recovering computing performance while |
---|
259 | maintaining physics performance.<BR> |
---|
260 | To enable the user to investigate its benefits, a mechanism is provided to |
---|
261 | deactivate this step limitation. The new method <TT>MscStepLimitation(bool)</TT> |
---|
262 | of <tt>G4MultipleScattering</tt> disables these new step limitations. |
---|
263 | In addition, in order to help the transition, the old version is available for |
---|
264 | this release 'frozen' in the class <TT>G4MultipleScattering71</TT>. |
---|
265 | Several examples (in extended/electromagnetic) provide sample physics lists |
---|
266 | which use this older version. |

269 | <B>Geometry modeler</B> |
---|
270 | <P> </P> |
---|
271 | For setups including parameterised geometries by material, an interface |
---|
272 | extension is introduced in <TT>G4VPVParameterisation</TT> base class for the |
---|
273 | <TT>ComputeMaterial()</TT> method. An optional argument has been added, that |
---|
274 | provides a constant pointer to the touchable of the parent of the current |
---|
275 | volume, enabling access to its copy number and other properties, and those of |
---|
276 | all its ancestor volumes. |
---|
277 | User code making use of this feature will have to be updated accordingly. |
---|
278 | A compilation warning should flag to take into account this interface change. |
---|
279 | <P></P> |
---|
280 | Internal classes implementing the framework for twisted solids have been |
---|
281 | renamed. User code depending on this framework will have to be modified |

282 | accordingly. |

285 | <B>Fast parameterisation</B> |
---|
286 | <P> </P> |
---|
287 | The concept of "envelope" and "ghost-volume" for fast-parameterisation has |
---|
288 | been merged with the <TT>G4Region</TT> in this release. Therefore, a |
---|
289 | logical-volume no longer acts directly as an "envelope", since this attribute |
---|
290 | now assigned to <TT>G4Region</TT>. Please refer to the User Guide for |
---|
291 | Application Developers for the detailed information. The relevant modules have |
---|
292 | migrated accordingly. See <TT>exampleN05</TT> which has been revised to |
---|
293 | demonstrate this new mechanism. |
---|
294 | <P></P> |
---|
295 | A design iteration has taken place for the GFlash fast shower parameterisation |
---|
296 | model and some classes were renamed to follow the new implementation and |
---|
297 | design for envelopes. User code making use of the GFlash tool should migrate |
---|
298 | accordingly. |
---|
299 | <P></P> |
---|
300 | TRD models for cluster parameterisation have been retired. The functionality |
---|
301 | is now provided directly as physics processes and included in the |

302 | <TT>electromagnetic</TT> packages. |

309 | this release. Also any protection from compilation warnings by the compiler |

310 | for deprecation of such header are no longer implicitely included. User code |
