    Hi,

    You will need to provide more details about the error message.  Is there an error number?  When does the error occur?

     

    Send text output from Radioss solver so we can see where it is happening.

    Thanks,

    Andy

     1.0e-8g is really, really small and likely what is causing issues though. Realistically, a particle of dust weight about 7.5e-7 g, so whatever your SPH particle is, it is a tenth of the mass of a dust particle. Consider whether you need this dense of an SPH mesh.
