The user should also input the phase-space?

This removes the restriction that charged particle steps must stop at all voxel boundaries and, thus, speeds dosxuznrc the calculation considerably. This ensured that the entire phase space source was sampled evenly over all parallel jobs. If any or all of the EGSnrc input parameters is missing, then the default setting will be used.

Dummy input used to be estepe, max.

However, the user may set this to correspond to any of the media that they have de? For example, in the BEAMnrc simulation, bit 10 may be associated with a manuall applicator, so any particle in the phase space? This will open up a window which gives you the di?

For the time being, please refer to the original article on these new sources for more details: The actual internal variable name associated with each input appears in brackets.

Otherwise, a default luxury level of 1 will be used. The centre of the phase-space is 80 cm from the isocenter and the collimator angle is 90 degrees. These extensions are either no longer used or are not supported and, thus, these authors are no longer included as authors of the users manual. A graphical representation of source 9 is similar to that of source 2 shown in Figure 3.

For non-CT phantoms where one can arrange to have at least some of the voxels quite large, the savings will be correspondingly larger, especially using the dsurround option see section These inputs are described in sections 5 and 6 below.

NRC shall not be liable in any event for any damages, whether direct or indirect, special or general, consequential or incidental, arising from the use of the software. Recall that when entering the input parameter the beam code, specifying the BEAM simulation to use, you simply use BEAM accelname, omitting the lib pre?

The time required for a given calculation is strongly dependent on the value of ECUT and thus it is important to use as high a value as possible. Note that since only one bit? This is only used in conjunction with photon splitting n split, see Section 8.

The partition of the phase space source that will be used for this one of the series of parallel input files for the same total simulation is given by: If this still results in many restarts because of many particles missing the geometry or beyond beam fieldthen re-run the simulation with NRCYCL set manually to: This is only of interest in keV X-Ray simulations.

Photons whose weight has been restored to the original weight are subject to splitting again.
