I am using the Eulerian multiphase model to simulate an air pressure wave that hits a cloud of particles. The geometry consist of a duct with a pressure outlet box in the end. The pressure wave starts in the beginning of the duct and the particles are located about in the middle of it. I have used field functions to define the volume fraction of the particles so that they form a half sphere along the bottom of the duct.
Field functionsqrt(pow($$Position[0]-2,2)+pow($$Position[1]+0,2)+pow($$Position[2]+0.25,2))<0.25)?0.02:0 What I want to happend in the simulation is that the pressure wave lifts the particles. My problem is that I always get the error: A floating point exception has occurred: floating point exception [Invalid operation]. The specific cause cannot be identified. Please refer to the troubleshooting section of the User's Guide. Command: RunSimulation CompletedCommand: RunSimulation In: [] error: Server Error I also canīt get any coupling between the particles and the pressure wave; the particles donīt move when the pressure wave hits them. The pressure wave on the other hand is affected by the particles i.e. swirls are formed. I am very grateful for any help I can get, really need it! |
