Hi there,<br><br>I am trying to simulate data using the following command;<br><br>datasynth -walkers 100000 -tmax 1000 -voxels 1 -p 0.0 -schemefile 17x17x17new.scheme -initial uniform -substrate cylinder -packing hex -cylinderrad 1E-6 -cylindersep 2.1E-6 > regcylinderfornewscheme.bfloat<br><br><br>The simulation works fine if I do it for 10000 walkers but reading the literature it is better to do such a simulation with 100000 walkers however, I get the following error on my PC when I attempt this;<br><br>Exception in thread "main" java.lang.OutOfMemoryError: Java heap space<br> at simulation.dynamics.Walker.<init>(Walker.java:98)<br> at simulation.dynamics.WalkerFactory.getWalker(WalkerFactory.java:51)<br> at simulation.DiffusionSimulation.initialiseWalkers(DiffusionSimulation.java:298)<br> at
simulation.DiffusionSimulation.nextVoxel(DiffusionSimulation.java:578)<br> at apps.SyntheticData.execute(SyntheticData.java:74)<br> at apps.EntryPoint.main(EntryPoint.java:266)<br>I understand you may not be able to help me but I do not know much about java and was wondering if you could shed some light on my problem<br><br>Many thanks in advance <br>Claire<br> </div></div>
