Control how many threads are used for the computation. Parallelization is possible if your license and hardware allow it.

The Parallelization Options dialog opens when clicking the Edit button and you can choose between Sequential, Parallel (Shared Memory), or Automatic Maximum of Threads.

Selecting Sequential will not apply parallelization and only one thread is used for the computation.

When Parallel (Shared Memory) is selected, the Number of Threads can be entered. Below, the Number of CPU Cores that the current machine has, the maximum number of Licensed Threads and the number of those licensed threads that are available (Available Threads) are shown in the dialog. Of course, the maximal number of parallel processes you can use, is the smallest of those three numbers.

If Automatic Maximum of Threads is selected, the number of parallel processes is automatically selected for optimal speed, based on the CPU cores and licensed parallel processes.

The Automatic Local Maximum of processes is automatically selected, which is the minimum of Number of CPU Cores, Licensed Threads, and Available Threads.

Select the Material ID for which the lineal path length distribution is calculated.

To determine the probability distribution of lineal path lengths, the algorithm generates a number of samples for each length. The Number of Samples specifies how many samples are generated per length. The Random Seed controls the random number generator. A different random seed results in the selection of a different set of random points. Increasing the number of samples increases the accuracy of the resulting distribution.

Choose how the maximal lineal path length is determined.

In the Automatic mode, the Maximal Lineal Length is set to the length of the smallest domain side.

In Manual mode, you can enter any value for Maximal Lineal Length in voxel.

If Periodicity is checked, the structure is treated as periodic in the selected directions. Thus, point samples can also be connected across domain boundaries.

If no Periodicity is selected in a direction, the structure is treated as encased. Thus, samples of lines where one point lies outside of domain are rejected.
