Question #683336 on Yade changed: https://answers.launchpad.net/yade/+question/683336
Status: Open => Answered Deepak proposed the following answer: Hi, I need to have a look at the case, boundary conditions and things to identify why this happens (my best bet is bad physics/numerical settings), paraFoam can be used to view parallel cases, did you have a look into the openfoam documentation/coupling documentation? The methods to post process parallel cases are there .. https://cfd.direct/openfoam/user-guide/v6-paraview/ https://yade-dem.org/doc/FoamCoupling.html#post-processing On Fri, Sep 13, 2019 at 11:09 AM Anqi H < question683...@answers.launchpad.net> wrote: > Question #683336 on Yade changed: > https://answers.launchpad.net/yade/+question/683336 > > Status: Answered => Open > > Anqi H is still having a problem: > Hi Deepak, > > I'm running the same simulation with icoFoam for 0.05s, the particles > are defined in fluidCouplingIDList and dynamic is disabled.
