Rather than each job running a? When n split is used with a phase space or BEAMnrc simulation source, then contaminant electrons may compromise dose statistics because they are fewer and will have a higher weight than the split photons which contribute most of the dose.

However, if the dose in the monitor chamber dosxyzznrc an important part of the calculation, lower values of ECUT may be required. If a particle originated in any one of these regions, then it is NOT used in the simulation. Input parameters for a phase-space source are: The code includes a restart facility and can be run on parallel computing platforms.

A graphical user interface for calculation of 3D dose distribution using Monte Carlo simulations

Default optimization is level 3 -O3. During a parallel run, output of. MS is to be used when Multiple Source models are to be used read the? A good rule of thumb for the setting of n split is: Spin effects spin effects.


Thus, if a phase space? There are two possible settings of Boundary crossing algorithm: Simulation through moving MLC with multiple variable settings 57 4.

For the reasons discussed in section 8. The position of the beam collimator is then de? This ensured that the entire phase space source was sampled evenly over all parallel jobs. Make sure to turn on for low energy applications, not necessary above, say, 1 MeV. Note that input is checked against min. If these charged particles undergo radiative events bremsstrahlung, annihilation, annihilation at restRussian roulette is played on the resultant photons with a survival 1 probability of n split.

Note that the number of histories to run and the total CPU time allowed for the simulation do not include the histories and CPU time from the previous run. All charged 1 particles survive with weight equal to n split times the original weight. If the source has only been restarted once and only a small fraction of it has been covered on the second pass, this is not likely to have a signi?



Thus, in order to get accurate uncertainty estimates, restarting the phase space? For the other mahual, the theory associated with the name given is used. When using this phase manuaal The positive sense of rotation is counterclockwise as one sights down the beam direction. To do so, put e. In the particular example shown in this? These other inputs are described in sections 5 and 6 below. There are three possible settings of this input: Dummy input used to be max.

A graphical representation of ddosxyznrc 9 is similar to that of source 2 shown in Figure 3. The positive sense of rotation is counterclockwise as one sights down from the origin in the phase space plane.

The incident angles theta and phi are de?

Russian roulette is played on all scattered photons with a survival probability 1 of n split. Voxel dimensions are completely variable in all three directions.
