Hallo everybody,

using particle studies a lot I randomly encounter the effect that Flow Sim stops the calculation of the particle trajectories issuing the error message "can not create starting points".

The main file is an assembly with a number of configurations. Having picked one these configurations to set up the first simulation all other simulations are simply clones of this first one using different configurations. That means that all simulations should be very much the same regards boundary conditions, mesh, simulation settings, cut plots and especially particle studies. The only difference between the configurations are a few smaller solid bodies that are actived in some configurations and deactivated in others.

A couple of particle studies are defined with different particle characteristics and different starting points. For all particle studies I would chose a surface and give the number of injection points. What is strange is that in some configurations the particle studies work perfectly while with others Flow Sim stops the particle study issuing the error message "starting points were not created. Failed to complete". I have no idea why this happens because to me there is no difference between the original simulation and its clone regarding the particle study setup.

Has somebody encountered a similar problem? If yes how did you solve this problem?

My setup: SOLIDWORKS 2016 x64 SP 5.0 and Flow Simulation 2016 SP 5.0 Build 3591 on a Windows 7 computer.

Thanks in advance,

Thomas
