floating point error in multiphase model -- CFD Online Discussion Forums

Sebastian Guest Posts: n/a	Hi, I tried to simulate an Eulerian Granular Multiphase model (gas-solids fluidized bed reactor) with more than 1 solid phase (2 or 3 solid phases with different mean diameters). I cannot start the calculation due to this error message right after pushing the iterate button: 'floating point error: invalid number Error Object: ()'. When I reduce the amount of solid phases to one, it works without any problems. I use Fluent 6.1.22 in the 2ddp mode and I modify the Syamlal-O'Brien drag law with a compiled UDF. Any help would be great, Sebastian.
